Timing Cover Oil Leak Fix

oily engine, timing cover oil leakOil 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!

  1. 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

      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.

      Thank you!

  2. hey, I have a 2003 lincoln navigator I just bought i was wondering if there’s anything I can do to seal a crack in the timing chain cover. not the gasket. Just to be able to drive it about 15 miles to my mechanics business

    1. Kevin-

      Thank you for asking about your Lincoln Navigator. Unfortunately, we do not manufacture a product for the type of leak you’ve described. Our Oil Stop Leak would only have an affect on rubber seals/gaskets. A hard part repair may be your best option.

      Thank you!

      Thank you for asking about your Toyota Yaris. Based on your description, we recommend using the BlueDevil Oil Stop Leak. As long as the leak isn’t more than seeping or lightly dripping, you would be a good candidate for the product. You should expect to start seeing results after 100-200 miles of driving.

  3. 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.

    1. 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!

  4. 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?

  7. 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

    1. 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. It would not have any affect on any other type of material. You would add the product the same place you add your engine oil. You should expect to start seeing results after 100-200 miles of driving.

  8. 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?

    1. 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!

      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 specifically 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!

  9. 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.

  10. 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.

    1. 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. As long as you are not losing oil too quickly, you would be a good candidate for the product.

      Thank you!
