need oil pump help!
hey guys im putting my LS1 back together now and need to know if there is a gasket or something that goes on the back of the oil pump-to- block surface? nothing came off with the old pump but im just making sure. thx!
Nope. Only thing you should have to worry about is the O-ring that goes on the pickup tube to the oil pump. Make sure you get it in there just right and dont pinch it or you'll have oil pressure issues.
