The Seafoam I used in my crankcase must have dislodged the sludge that was plugging a gasket. It actually runs better after using it so I don't think any damage was done.


Lifetime warranty covers leaks beyond operational seapage so I'm not too worried about leakage that comes from an aging engine.

 

I haven't seen leaks but it's also been part of a "normal" schedule for me so the gunk doesn't have long to build up. Where are you seeing the leak?

 

Not ar the oil pan gasket, but the one above it at the back.
