antiextreme Posted May 19, 2016 Report Share Posted May 19, 2016 I've removed the old rear main out of my L18 and inserted the new one. I did what I could by hand and then worked it with a block of wood and a hammer. I was able to get it to a point where it doesn't feel like it wants to go any further but it is not sitting totally flush with the block. I mean it is microscopically sticking out, maybe a millimeter. I'm afraid of damaging the seal if I try to hammer on it any more but I'm not positive that it has gone in all the way. I don't imagine it has bottomed out. Could that be possible? Any advice? 2 Quote Link to comment

Draker Posted May 20, 2016 Report Share Posted May 20, 2016 It's probably fine. Use the old seal, place over new seal. Tap on it.. and see if it seats better. 1 Quote Link to comment

MikeRL411 Posted May 20, 2016 Report Share Posted May 20, 2016 "Old world info" don't put the rear seal flush with the block and pan! Leave a slight offset, use Permatex on the mating surfaces and bolt up. The offset prevents bypass leakage due to the interupting flanges of the rear main seal. 1 Quote Link to comment
