#FRONT TIMING COVER LEAK PROFESSIONAL#
If you suspect that your timing belt may be leaking, have the vehicle inspected by a professional technician at V&F. Products like these are only band-aid fixes– because they don’t fix the root of the problem, you will eventually have to pay for a replacement and the temporary solution can damage other parts of the engine in the meantime. But these products tend to do more harm than good. These additives can be added to your engine oil and claim to “restore” your timing cover gasket to its original shape and size sealing the leak and keeping your car running without a trip to the mechanic. If you think you may have a timing cover gasket leak, but don’t want to pay the high price to replace the gasket, it’s tempting to buy “Stop Oil Leak” fluids. All these things add a lot of labor to the process and make replacing the gasket with a relatively expensive maintenance item. Oftentimes, other parts like the alternator, power steering pump, and air conditioning compressor must be moved or removed to replace or repair the timing cover gasket. The timing cover gasket can be fairly expensive to replace due to its location and all of the parts and accessories surrounding it. This makes timing cover leaks extremely difficult to diagnose if you’re not a well-trained technician.

Others have a timing chain, which have 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. Some vehicles are equipped with a timing belt, which is mounted external to the engine’s lubrication system, so your engine won’t have a timing cover gasket to leak. Diagnosing the Problemīefore you worry about having a leak in your timing cover gasket leak, you should know that not all vehicles have timing belts. It can leak at some times and not others and leave drips in odd places, leaving you wondering what the problem is. But a timing cover gasket leak can spread oil all over your engine.

This also makes me wonder the high cost of sealing this timing chain cover during the new engine assembly by Mazda.
I believe thats why Kedis82ZE8s Mazda dealer couldnt fix the problem after 2 tries. The repair procedure is complicated and its hard for the tech not to screw it up. If you read the TSB which features very detailed explanation of why the front timing chain cover leaks, and how the Mazda dealer would fix the problem. I, for one, wouldnt want to do that just for checking these leaks, until to the time Im changing the ATF. That means you need to take the under-cover down in order to see the leaks. But if you follow that long thread Kedis82ZE8 created more than 3 years ago, you would find it takes some effort to detect these leaks from BOTTOM. Most would assume this wont happen to a fairly new engine. Click to expand.Firstly, most people including me, wont bother to look for these engine seepages or leaks. Fel-Pro calls this gasket 'year 2000 technology for a engine designed in 1955.' The one-piece design eliminates four possible leak points and makes it easier to install.
