Guys,



When I put my 312 together I used a neoprene rear main seal. The engine leaked from the beginning.



It only leaks until the engine gets one quart low on oil. ????? With 4 qts in the pan it doesn't leak at all. What gives.... Could this be a pan gasket and not a rear main leak?



Also when it has 5 qts in the pan she leaks from the draft tube. I have another dip stick and it also reads full with 5 qts in the motor.



No I'm not smoking any rope seal.



Got any ideas?



Jim
