Q: Seal leaking

asked by on

The rear main oil seal is leaking.

A rear main seal leaking on this engine is very common. The transmission must be removed to change it. I have seen this also occur from a failing PCV valve. It is it not functioning too much crankcase pressure can build up and force oil from the rear main seal. I would typically check this first and then fix the rear main seal if not progress is made. If you need to have this checked, consider YourMechanic, as a certified mechanic can come to your home or office to locate and repair the leak.
