hey guys.

I just checked out a type s engine. Did a leakdown on it with results 20% in cyl. 1,2 and 4. Cyl 3 wax leaking 40%. Now, i would like to know if these are decent numbers, mind you, the engine is not sitting in a car and not a normal operating temperature. test was done with engine sitting on the ground. Im guessing the valve seals are fully expanded.

Also, there was an oil stain on the cardboard the engine was sitting on. Looked under the engine and saw (what i think) a chip where the tranny casing meets the block. The chip is on the tranny side and goes through the casing (oil leaking). What could have caused this?

please help out
thanks
