Yes, there are additives specifically designed to help seal leaks in gaskets, including timing cover gaskets. These products usually contain sealant compounds that can expand and fill small gaps or cracks. However, while they may provide a temporary fix, it is generally advisable to replace the gasket for a permanent solution to prevent further leaks and potential engine damage. Always consult your vehicle's manual or a professional mechanic for the best course of action.
No
Replace The Timing Cover Gasket
Yes, if there is internal leak.
Might I suggest that either the leak was/is not at the timing cover gasket, or maybe something went wrong on the gasket install?
Mine is in the timing chain cover gasket. You can find your leak by pressure testing your coolant system.
Common leak points are oil pressure sensor, oil pan, and timing cover gasket.
I wouldn't recommend it. Replace the gasket.
You probably need to drop the oil pan down, remove the front cover and replace the cover gasket and main seal.
Maybe oil passage leak by gasket in timing cover
No, there is a gasket.
Water pump, radiator, thermostat gasket, timing cover gasket, and freeze plugs are the most common.
It is mounted to the timing cover, and any gasket can start leaking for any reason, including just plain old age. Gaskets are not infallible, they will leak from time to time.
