I think I found where my oil is coming from. After watching it run while on the ramps, I noticed oil coming from a weep hole on the drivers side just below the head in the rear of the motor. It backs up to the bell housing. Is this the rear main seal going bad and can it be replaced without taking off the intermediate flange assem. after the trans. is removed? I have an 82 380 sel 126, w/ a 116. 96 motor. Thanks!! les
