When I bought my car I knew it had an oil leak, but I wasn't too worried about it. Well now its getting on my nerves and I want to get it fixed. I believe the leak was caused by high compression mixed with 12psi sc (the reason I think that this is the casue is because the stroker motor only has about 15,000 miles on it). If a car was to get an oil leak from this anyone know which gasket it would be?

 

Lets try this in the FI Forum, transfering.
Thanks.

 

I would guess the oil pan would go first. Then maybe valve covers. Maybe rear main seal. Who knows?

Don't you know where the leak is coming from? I had those cork gaskets on my valve covers(on my Mustang) and they loved to work loose(the bolts).

First, find the leak!

 

I am leaning towards oil pan or timing chain cover. Just had the rear main seal replaced.

 

anyone else have any thoughts?

 

When I first built up the motor I had an oil leak from the rear main and the seal for the opti spark.

I fixed the opti leak and tried to fix the rear main twice but never go the rear main fixed.

This year for the rebuild I have bought an electric vacuum system for crankcase ventalation. At 12 psi, oil leaks from crank case pressure is a real and onging concern.

 

Try some dye in your oil and use an ultraviolet light to help locate the source.

I had a nasty leak that I originally thought was the oil pan. After replacing the gasket twice to no avail, I finally decided to replace the timing chain cover gasket. Low and behold, about 2 inches up, on each side, there were obvious breaks in the gasket. It had been fine for 2 years and the leak came on literally overnight. No change in my setup, running 6 psi. Go figure.

Try the dye though, it may help you narrow down your source.

 

I used dye to track down my leaks. Timing chain and intake.
