Timing Cover Gasket Leak

timing cover gasketTiming cover gasket leaks can be one of the most elusive leaks your vehicle can get.  Many leaks leave obvious indications in certain places that make it quick to tell what the problem is.  For example, if you’ve got an oil pan gasket leak, it’s obvious because you won’t find any oil above the oil pan gasket, meaning your entire engine will be clean except for the oil pan.  On the other hand, a timing cover gasket leak can spread oil over most of your engine, leave drips in odd places, leak sometimes, but not others, and be generally elusive.

To start to determine if you’ve got a timing cover gasket leak, you’ve got to figure out if that is even possible on the motor in your car.  There are two main ways an engine keeps the timing consistent between the crankshaft and the camshafts.  It’s important to keep the timing between the crankshaft and camshaft consistent because the cam drives the valve train and it’s important to keep the valves opening and closing in proper relation to the piston’s movement to maintain the maximum engine efficiency.  To keep these things in sync, some engines use a belt that runs from the crankshaft and drives the camshaft to keep things in time, while other types of engines use a chain.  Belts are quiet and efficient but require regular replacement to keep them in good condition since they are not lubricated.  On the other hand, timing chains take a little more energy to run but they are extremely robust since they are lubricated by your engine oil and rarely if ever, need to be replaced.

If your vehicle is equipped with a timing belt, then it will be mounted external to the engine’s lubrication system so your engine won’t have a timing cover gasket to leak.  If your vehicle has a timing chain, there will be a cover over the chain and drive gears to contain the engine oil so it is very possible that is where your leak is coming from.  To tell which type of engine you have in your car, check your vehicle’s owner’s manual.  If the list of required maintenance items includes replacing a timing belt between 50,000 and 100,000 miles, then you have a timing belt and won’t have a timing cover gasket leak.  If you having a timing belt and notice an oil leak coming from the front of your engine, try reading our article about camshaft seal replacements to see if that is where your leak is.

Since the timing cover must surround the entire timing chain, which runs from the engine crank up to the camshafts, it’s a large cover with a large gasket.  Also, as you drive, the timing chain whips oil from down on the crank all the way up to the top of your engine so a leak could appear anywhere from the bottom to the top of your engine making them difficult to diagnose.

The timing cover gasket can be expensive to replace due to its location and the accessories surrounding it.  Often, things like the alternator, power steering pump, and air conditioning compressor must be moved or removed to change the timing cover gasket.  All these things make replacing the gasket a relatively expensive maintenance item.

If you think you may having a timing cover gasket leak, but don’t want to pay the high price to replace the gasket, there is an alternative!  BlueDevil Oil Stop Leak is an oil additive you can simply add to your engine oil that can restore your timing cover gasket to its original shape and size sealing the leak and keeping your car running safely without a trip to the mechanic!

      Based on your description, we recommend using the BlueDevil Oil Stop Leak (http://store.gobdp.com/oil-stop-leak-49499/). The Oil Stop Leak is a universal application and would treat oil pan gaskets, valve cover seals, rear main seals, etc., where as the Rear Main Sealer is specifically formulated for the rear main seal. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!

          There is not a specific rpm that the vehicle needs to reach during idle to achieve results. Feel free to contact our technical support line at 888-863-0426 with any other questions.

          Thank you!

  1. 2005 Pontiac Aztek have front timing cover leak. What is the recommended product? Had a trip to mechanic and he says to replace it will take $1000++.

  2. 1997 Taurus leaking coolant I believe. Thought it was water pump but mechanic said probably Timing Cover Gasket. I am not spending the money to fix it, old car just need few more months of it. Which product is best? I don’t think its oil.

    1. Justin-

      Thank you for asking about your Ford Taurus. Based on your description, we recommend using the BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/) for your leaking timing chain gasket. As long as the vehicle will maintain idle for a full 50 minutes, and you are not losing more than about a quart of water/coolant in that time span, you would be a great candidate for the product.

      Thank you!

  3. I have a 2001 Ford F-750, with a Caterpillar 3620 engine. My mechanic told me it has a “gear cover gasket leak.” It is sometimes sporadic, and frustrating. Don’t really want to spend nearly 3K to replace the gasket (mostly in labor charges).

    Is there a product that will help cure this issue?

    1. Don-

      Thank you for asking about your Ford F-750. To confirm, are you losing oil or water/coolant? 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!

  4. I have a 2008 ford fusion with 95,000 miles and I just found out the engine has a timing cover and oil pan gasket leaks. The cost to repair is $2,800 but not sure it’s worth the cost.

    1. Ed-

      Thank you for asking about your Ford Fusion. Based on your description, we recommend using the BlueDevil Oil Stop Leak (http://store.gobdp.com/oil-stop-leak-49499/) for your timing cover and oil pan gasket leak leaks. As long as you are not losing oil too quickly, you would be a great candidate for the product. You should expect to see results after about 100-200 miles of driving.

      Thank you!

    2. That oil pan gasket ain’t nothing to change, it’s the cost of gasket and my time. Timing cover is something more involved, much more in most cases.

  5. I just had my 2003 Chevrolet Malibu into the mechanic and they say the timing cover gasket needs to be replaced. They say the car is leaking both oil & coolant. They could tell me how much, but that it’s more oil than coolant. To repair will be $700+ and then I found this website when I was trying to learn about my cars problem. I did monitor the car and over the period of 11 hours I had 7-8 quarter sized drops. Is my car a good candidate for your product?

    1. Aimee-

      Thank you for asking about your Chevrolet Malibu. To confirm, the timing cover gasket is leaking both oil and coolant? How quickly are you losing coolant? With use of the BlueDevil Oil Stop Leak, you would be driving the vehicle, typically between 100-200 miles before seeing results. As long as the vehicle isn’t overheating and you can top the system off with coolant as needed, you may still be able to use the product. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!

  7. I have a 2011 Toyota Prius. I’m told that the sealant on the Timing Chain Cover is leaking oil. Would your product work for my situation?

    1. William-

        Yes, BlueDevil Oil Stop Leak is safe and compatible to use in your Toyota Prius.  We recommend adding 1 bottle of BlueDevil Oil Stop Leak to stop your timing chain cover leak.  Expect to start seeing results after approximately 100-200 miles of driving.

      Thank you!

      1. Thank you! I have to use full synthetic oil in my car – this should work with that, right? Also, I assume that I don’t have to drive 100-200 in one setting after applying. Is that correct?

        1. William-

          Absolutely, the BlueDevil Oil Stop Leak is compatible with synthetic oil. The 100-200 mile drive time does not have to be a continuous drive. You are fine to drive the vehicle like you normally would, it would just be around 100 miles before you would start to notice some kind of improvement. Feel free to contact our technical support line at 888-863-0426 with any other questions.

          Thank you!

  8. I have been losing coolant (issue ongoing for almost a year), but was initially thought to be due to cracked faulty cap that it was evaporating/being lost. Filled it up during the year, but forgot to check it last couple mths. Last week, heater stopped working in car, and fan started to kick in on short journeys, as if car was overheating, then oil light (red) came on, so had it checked by garage. They confirmed timing chain cover gasket is required – along with possible oil change due to coolant leaking in there.. assuming in this case given the overheating and critical oil light showing that its too late for this product and best to go changing gasket cover? Thanks
    And car type: 2007 Opel Astra (petrol)

  9. Hi. My Aztek just have a coolant leak after the engine shut off. Possibly water pump but do you have any recommended product for this leak? Thanks.

    1. Han-

      Thank you for asking about your Pontiac Aztek. Unfortunately, we do not manufacture a product intended to seal leaking water pumps. A hard part repair may be your best option.

      Thank you!
