Oil leaks can be difficult to track down the exact location of the leak. They also can vary widely in repair costs from less than $100 to over $1000. Also if you aren’t seeing drips on the ground do you really need to fix it?
We’re going to talk about a timing cover oil leak, it’s potential fixes, and how to decide if it’s worth spending the money on in your vehicle to help you live a leak free life!
Timing cover oil leak repairs tend to be some of the most expensive oil leak repairs that you can have done on your vehicle. To understand why it’s important to understand what your timing cover is. The timing cover on your motor is at the front and is a large cover that goes over your camshaft timing components, most usually a timing chain. If your vehicle has a timing belt there isn’t a need for a timing cover on your motor as the timing components aren’t lubricated with engine oil.
The timing cover is a notorious leak location on many vehicles due to the timing cover’s large size, awkward shape, and multiple joints that need to be sealed. On top of that, your timing cover will also have an oil seal where your harmonic balancer is attached to the front of your crankshaft. Before you pull your timing cover off make sure your oil leak isn’t actually coming from this seal! The harmonic balancer seal is much easier to change than the timing cover gasket so if you can prove that seal is your leak location, you can save lots of time and money!
If you do end up having a timing cover oil leak, the good news is it’s probably not that severe. Since the timing cover is just a cover, there isn’t any pressurized oil behind it so leaks are often relatively slow meaning if you absolutely need to, you can keep driving with this leak as long as you keep an eye on your oil level. The real danger of driving with a timing cover oil leak, besides a low oil level, is getting engine oil on your engine belt. The oil will degrade your engine belt quickly and can allow it to slip on the pulleys it drives which causes a new set of problems and can leave you stranded and damage your engine. If you’ve got an oily engine belt, fix your timing cover oil leak ASAP!
Timing Cover Oil Leak Fixes
The only two options for fixing a timing cover oil leak is to restore the gasket or replace the gasket. BlueDevil Oil Stop Leak can restore your timing cover gasket or front crank seal stopping your oil leak if repacing the gasket doesn’t make sense if your vehicle.
Replacing the timing cover gasket often requires removing the valve cover gaskets and oil pan gaskets so it’s a great time to replace them as well! Doing this job generally will leave your engine completely leak free and looking like new!

Hi
I have a 2001 Mitsubishi Montero Sport, it has been blowing a lot of white fine smoke. I felt it was a head gasket leak and went ahead and purchased the Radiator and block sealer, I went through the process as described on the container and it did not help. my next step was to purchase the large Head Gasket sealer, I have used approximately 3/4 of the container and there is still a considerable smoke emission.
My question is should I put another bottle through, run the engine more (I have not been on the road much because of the smoke)
I would appreciate any suggestions. Thank You. Wally Eagle
Walter-
Thank you for asking about your Mitsubishi Montero Sport. When did you use the product? According to the capacity table, you should have been using a little less than half of the 32 oz. bottle for your 10.6 quart capacity cooling system. Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

Hi my TJuana Timmons I have a 2007 Mazda cx-7 and I have a oil leak from the timing cover and the rear main seal,, what can I do to fix it
Tjuana-
Thank you for asking about your Mazda CX-7. Based on your description, we recommend using the BlueDevil Oil Stop Leak. BlueDevil Oil Stop Leak is more concentrated and is the universal application that will work for various leaks such as oil pan leaks, rear main leaks, valve cover gasket leaks, etc. Whereas the Rear Main Sealer is less concentrated and is formulated exclusively for leaking rear main seals. If you are not 100% sure where the vehicle is leaking or there seem to be multiple leaks then we recommend using BlueDevil Oil Stop Leak. It is not necessary to add both products simultaneously.
Thank you!

I have a 2011 Range Rover Sport took it dealership they said there is a small leakat the timing cover . How much BlueDevil Pro on this vehicle? It’s a 5.0 not a supercharger
John-
Thank you for asking about your Range Rover Sport. To begin, you would use about 1/2 of the bottle (6 oz.) of the BlueDevil Pro for your timing cover gasket leak. You should expect results after about 100 miles of driving. If the leak persits, you would use the second 1/2 of the bottle after your next scheduled oil change.
Thank you!

Thank you. I forgot to add that two different dealerships’ repair cost were quoted as just under $4000 for one dealership, and the other dealership’s quote was nearly $7000 3 months later. However, I still so no signs of an oil leak; no smoke or low oil volume.
Thanks again.

I just brought my Toy Corolla 2010 (eng 1.8 liter) to the dealer and they recommended to replace timing cover/gaskets. Estimate: $1984.00.
I don’t see any oil leaks. At least I can’t see what they see. My car runs very smoothly and the also recommended shocks/struts and boots.
I most definitely need a second opinion or third if possible.
Gil-
Thank you for asking about your Toyota Corolla. It’s possible the dealership is making these recommendations based on mileage and the manufacturer’s maintenance/service schedule for that mileage. It may not be necessary to get a second or third opinion if this is the case, as there may not be an immediate cause to have the timing cover gasket replaced.
Thank you!

The same situation on the same car 2010 Toyota no issue just went for a oil change they quoted 3361.00 for timing cover reseal I only have 94,000 miles on this car and do all my required maintenance they also recommended ft axle replacement 1327.00
Hello I have an 2008 lexus 350 I have my oil changed today 6/24/2020 a not on my bill indicated my timing cover is seeping the repair shop indicted they would monitor it. How serious of a problem is this if so should I have them repair it . I’m 91 years old & do not understand problems such as this. I did not know that this model of lexus had a timing belt or chain.
Ken-
Whether the leak is coming from the timing cover or timing cover gasket, the problem would be the potential of oil getting onto the belts. Oil on the belt could cause it to slip on the pulleys it drives, which causes a new set of problems and can leave you stranded and damage your engine. It would be best to have the timing cover replaced sooner, rather than later.
Thank you!

Hi
I have a 2005 Toyota Matrix. The local Toyota dealer inspected the vehicle recently and said the timing cover is leaking oil (they showed it to me). The leak isn’t too bad yet, as I have not added any oil since changing it 3 months ago and it is not leaving any drips where the car is parked. However, they said the gasket is probably failing and it will get worse over time. What do you recommend?

Hello –
You say “If your vehicle has a timing belt there isn’t a need for a timing cover on your motor”. I have a 2011 Audi A4, quattro, manual transmission, and I believe it has a timing chain instead of belt. I am bit confused about you sentence and how it relates – is there NO leak if car has timing belt then?
Nonetheless, when looking under the car, there appears to be a very small leak (about 1 pint in 4 months) coming from the top, from likely the timing cover. At first I thought the drain plug was not secured tightly so I had replaced with new. The oil pan gaskets look moist but does not seem to leak oil (Wiped clean and checked after an hour).
I wanted to know if this product can solve this small leak, and where do I pour the solution??
Thanks
Oswald-
Thank you for asking about your Audi A4 Quattro. The BlueDevil Oil Stop Leak would be able to stop a leak coming from the timing cover gasket. The product is intended to treat rubber seals/gaskets.

I appreciate your reply… Just bought one, shipped and sold by Amazon. TY
i have a 2000 plymouth neon. just over a year ago i swapped out the original engine,with very high mileage,and replaced it with a lower mileage engine. at that time we replaced the timing belt, gasket seal, and water pump. i’ve put on maybe 20 k since then. recently we replaced a bad crankshaft sensor and discovered oil leaking onto the belt. must have come through the gasket seal. the gasket seal is still relatively new and should have prevented oil leaking onto the belt. so how would blue devil help reseal and prevent oil leaking onto the belt whose gasket seal isn’t that old and should still be in fairly good condition?
John-
Thank you for asking about your Plymouth Neon. Keep in mind, age can also play a factor in the longevity of a rubber seal/gasket. Based on your description, we would recommend using the BlueDevil Oil Stop Leak. The product is intended for leaks that are seeping or lightly dripping, and would be able to seal a leaking timing cover gasket.
Thank you!

Hi I have a 2000 Toyota Tacoma 2.7L Prerunner, love the truck to death body has 263k and a rebuilt engine with only 110k on her. I noticed a small oil leak when parked on an angle on a driveway and took it into the shop had it lifted and inspected with the results of my mechanic saying that the timing chain cover had a very small leak. Mechanic quoted me 1300$ for the job but also said its not dire with the small leak. He said its safe to drive but to carry oil and check levels every couple weeks. MY father recommend this product and swears by it. What do you think? Im a broke college student trying to save my daily driver.

Is this a one time application or will I need to add it each time I change the oil? I have a 2012 Ford Escape and was advised by the mechanic at the dealership I had a timing cover leak, and that it would be over $1400.00 to fix it. I’m a senior on a fixed income and need another option. I’m hoping this product will work.
Deborah-
Once the product seals, it would be a permanent seal. You should only need to use the product once. It is not one of those things that needs to be added with every oil change. As long as you are not losing oil too quickly, you would be a good candidate for the product.

Hello, my 2006 Cadillac DTS appears to be leaking from a few areas: the timing cover seal, oil pan gasket, and maybe a valve cover gasket. I’d like to know which stop leak product you would recommend I try for reconditioning these seals? With so many leaks should I even make an attempt with a seal conditioner or would it be better to just drop the engine cradle and reseal the engine? The car is at 120,000 miles, so I’m sort of at that point where I’m wondering if it’s worth dumping more money into it.
Brian-
Thank you for asking about your Cadillac DTS. Based on your description, we recommend using the BlueDevil Oil Stop Leak. The product works by revitalizing and reconditioning rubber seals/gaskets, and would be able to seal leaks coming from the areas you’ve described.

Hi I’ve got a 2010 Aston Martin V8 Vantage with a small timing cover leak, I’m worried about putting your product in the engine to stop the leak.
1/ It’s a dry sump system does this have any bearing on how it works ?
2/ does the product effect the way the oil lubricates the engine ?
3/ is there any gum or residue which could effect any engine parts
4/ The car has the oil changed annually do you need to add the product again to the engine oil again to keep the leak at bay.
Thanks in advance
Chris-
Thank you for asking about your Aston Martin. The BlueDevil Oil Stop Leak is 100% safe to use. The product does not harden or thicken in anyway, so it would not clog flow or restrict ports. It does not “gum up” what so ever. Also, the product does not affect the viscosity of the oil. Once the product seals, it would be a permanent seal. It is not the kind of thing you would have to add with every oil change.
Thank you!

I have a 2002 Chevy S10 4.3 l that we have replaced the timing cover twice and it’s still leaks What seems to be the problem can you please give suggestion
Steven,
Thanks for your question about your 2002 Chevy S10. Usually, if timing covers continue to leak it’s either because something is warped or the wrong sealant was used. After years of heat cycling, the timing cover can get warped or the alignment of the oil pan can change on the engine block, or sometimes even the engine block can get warped. This would make it difficult to get a good seal on the timing cover. If your timing cover uses a paper or rubber gasket this can be especially true. We recommend using an oil resistant RTV like Permatex Black Maximum Oil Resistance RTV. Ensure to use enough to seal but not so much that it will squish into your engine or oil pan. It is also important to let it dry for 24 hours before using your truck again.
Thanks again for your question!

Hello, I have a 93 dodge dynasty with a 3.0 engine 6 cylinder car that has been leaking oil from under the passenger side of my car and put about 2-3 quarts of oil in it every couple of days. I have been told many different reasons as to what the problem is so im confused. I was told it was the timing cover gasket and it would be over $1000 to fix then I was told it was the valve cover gasket seal? So I just replaced the seal. Blue devil stop leak has bn highly recommended so I just purchased one and going to use it tomorrow. Do you think I’m at least headed in the right direction??please reply back saying that this looks promising. Thank you

Thank you for asking about your Ford Escape. Unless you are due for an oil change within the next 300 miles, you would be fine to add the BlueDevil Oil Stop Leak to your existing oil. If you do plan on changing the oil, it is not necessary to add less oil than usually would. The 8 oz. of product wouldn’t really be enough to move the level.

I recently had my valve cover gasket replaced and then was told that my timing casing was leaking oil on my 2016 Mazda 6. Could they be related issues and the second shop saw the oil from the first issue? I’m having trouble qualifying a $600 repair.
Adrian-
Thank you for asking about your Mazda 6. It would be difficult to say whether the original leak was repaired when the valve cover gasket was replaced or if the timing cover was the culprit for the leak the whole time. It is never a bad idea to get a second opinion in a situation like this. It is possible to have multiple leaks at the same time, so it is also possible both components were leaking originally and only the valve cover gasket was replaced, leaving you with the leaking timing cover gasket.
Hope this helps!

There does appear to be some oil in those areas but my car does not have any noticeable leaks on the ground. I’d like to try Blue Devil, but I’m not sure whether I should use the Oil Stop Leak product or the Rear Main Sealer. Or perhaps I need to use both?
John-
Thank you for asking about your Honda Accord. The BlueDevil Oil Stop Leak is more concentrated and is the universal application that will work for various leaks such as oil pan leaks, rear main leaks, valve cover gasket leaks, etc. Whereas the Rear Main Sealer is less concentrated and is formulated exclusively for leaking rear main seals. If you are not 100% sure where the vehicle is leaking or there seem to be multiple leaks then we recommend using BlueDevil Oil Stop Leak. It is not necessary to add both products simultaneously.
Thank you!

I have a oil leak from the timing chain cover of my 2011 Ford Escape V6 engine. What product can I use to stop the leak? Does your addditive have any negative affect on the oil or other parts of the engine?
Dan-
The best product to use for the timing chain cover gasket leak on your Ford Escape is the BlueDevil Oil Stop Leak. The product does not harden or thicken in anyway, so it would not cause any adverse effects. Expect to start seeing improvement after 100-200 miles of driving.

Hi BDP, I have a 2009 Audi a4 quattro, 3,2. with about 111K on the clock. I thought I had a leak in the power steering due to low fluid in the reserve according to the wife, so we brought it into the shop. The shop reports the upper and lower timing cover gaskets are leaking. They report it will be 22 hours in shop labor
($$$$$) due to the difficulty in repair. The same shop changed the valve cover gaskets less than 3K ago as they indicated THAT was the location of the oil leaks were located. Any thoughts on this unusual, recommended repair? Love the car and having trouble keeping the return on investment (ROI) in mind.
We will be using the Bluedevil Pro Steering fluid sealer having just read about it on this cool web page. TIA
Jerseybob-
Thank you for asking about your Audi. To confirm, the shop didn’t diagnose an issue with the power steering? Did you ever notice oil leaking to the ground? It wouldn’t be uncommon for the timing cover gaskets to wear down over time and develop a leak, however, unless both timing cover gaskets are leaking, it wouldn’t be necessary to replace both. Based on your description, we’d recommend bringing the vehicle to a different shop and get a second opinion. The second shop could confirm what the first shop quoted or give you completely different recommendations.
Hope this helps!

Thanks for your website gave me a idea I will be trying BlueDevil in 2009 ram 2500 which has a oil leak in front of the motor a diesel 7.3 cumming.
I have a 2006 Toyota Avalon and it has a timing cap leak. Would this be recommended to use on my vehicle?

At only 60k my timing cover gasket is leaking. It’s huge job to replace it. Should I replace the timing chain just because I’m in there?
William-
It is typically recommended to replace the timing chain at 100,000 mile intervals. You do not necessarily need to replace the timing chain when replacing the timing chain cover gasket, however, it wouldn’t be a bad idea.
Thank you!

My 2013 f150 3.5l ecoboost has a timing cover gasket leak. It isnt so bad it spots the ground but can smell burnt oil. Will BlueDevil Stop leak hurt my engine in any way whatsoever?
Gary-
No, the BlueDevil Oil Stop Leak would not harm the engine whatsoever. It does not harden or thicken in anyway, so it would not clog flow or restrict ports.
Thank you!

Hi , I have a 2006 Lexus ES350 with 140000 miles. Recently I found the oil leak in the floor of Garage around 5~10 drops overnight. After confirming by my technician, he said this is high possibility from the upper timing cover. For Lexus ES350, to repair it oculd cost $3000 and need to tear down all engine set. My question is if I use Bluedevil oil stop leak, can reduece the leak or repair it? Thanks.
Kevin
Kevin-
Thank you for asking about your Lexus ES 350. Yes, the BlueDevil Oil Stop Leak would be able to seal the timing cover gasket leak you’ve described. You should expect to start seeing results after 100-200 miles of driving.

I have a timing chain as opposed to a timing belt. If oil leaks onto the chain is that a big problem? Or is that only a problem for belts.
Zach-
Oil leaking is a problem in general. Overall, timing chains tend to last longer than timing belts, as belts dry out and crack over time.
Thank you!

Hi. The Toyota dealer has identified a fluid leak in the engine of my 2011 Prius. They say they need to reseal the timing cover. Cost $3,811.40. Can you let me know whether this sounds reasonable, (it does not sound reasonable to me), and what my options are to deal with this problem?
Thank you! EB
Edward-
That cost does seem a bit high. Typically, replacing the timing cover wouldn’t cost more than around $1,500. You may want to shop around and get second opinion.
Thank you!

Would a Blue Devil product, like “stop oil leak” or something more specific for timing belt cover reseals, work to help this issue without spending the 2,300 the dealership I bought my Yaris from wants to charge me to fix it. Ironically, they also want to buy it for trade-in from me for 2,200.
Caroline-
Yes, the BlueDevil Oil Stop Leak would treat a leaking timing belt cover gasket leak. As long as you aren’t losing oil too quickly, you would be a good candidate for the product. You should expect to start seeing results after 100-200 miles of driving.

I have a 2017 infiniti q50 sport 3.0t and was told I have a leak from my timing chain cover. Which blue devil product will fix this leak? I assume it is a small leak as oil level was not low. Thanks
Michael-

Where exactly do you pour the BlueDevil Oil Stop for the QX 60 2018. The dealer is recommending resealing the timing cover and head gasket even though we don’t see any leak?

I have a 2012 Ford Flex with the 3.5l engine. Is BlueDevil Oil Stop Leak ok to use on the timing cover plate?
Jay-
Thank you for asking about your Ford Flex. The BlueDevil Oil Stop Leak is specifically intended to treat rubber seals/gaskets, so it would work for a timing cover gasket leak. Unforntately, the product wouldn’t have any effect on metal or any other type of material.
Thank you!

My 2016 Lexus RX350 F Sport is leaking at the timing cover. My understanding is that this is a common problem for this model. Leak is very light. Do you have a product that would address this? Alternative is to pay upward of $5k to drop the engine. One more question if I might. Assuming you have a product that works on my vehicle, how often would I add it? Every oil change? Thanks for your help!!
