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!

  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

      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.

      Thank you!


  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.

      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!

      We recommend using the BlueDevil Oil Stop Leak for the timing chain cover gasket leak on your Volvo XC90. You should expect to start seeing results after 100-200 miles of driving.

      Thank you!
