Having problems with your 2001 Oldsmobile Alero ?
2001 2.4l alero. Oil leaking like crazy only under pressure. Leaking from the back of the block near oil pan. all sensors are in to my knowledge. Found a threaded hole where perhaps a plug was in at one time and fell out. got lucky engine didn't blow.
Could be rear main oil seal if it is not that oil galley plug u found
