94 suburban 350 motor. After it being rebuilt and starting it found out we have low oil pressure, very very little oil going to the heads and i think we spun a bearing i think or the pick up tube came undone cause theres a clunking sound when the motor is turned off not while running though the thing is though theres oil squrting thru the rear main and dripping thru the dust shield. The question is, is it possible that the oil pump pick up tube is off and the pressure is shooting out of the rear main or whats your thoughts. Havent pulled the pan off to investigate yet its just pissing me off <img src="/forums/images/graemlins/zombie.gif" alt="" /> I just hope the rear seal will re-seal after the probalem is fixed.
