Moroso Deep Sump…Oops

[ntsqd]

Some will argue that a gasket should seal by itself. I don't disagree, but that assumes ideal install conditions. Doing the pan while in the vehicle is not what I'd call "ideal conditions." I'd be tempted by either Hylomar or Right Stuff, at least in the corners where the gasket transitions from flat to arched.

I put right stuff on those areas on the engine side so I find it strange that it’s leaking. It’s a complicated gasket with those billet ends on the pan and I’m guess it moved a little and isn’t in the grooves in those ends perfectly.

Yeah, I totally feel the same but it isn’t a brand new engine from the factory.

I forgot how much of a pia this upgraded rear main seal is to do. It has a metal ring on the engine facing edge for positive stop and support which make it such a pain to get into place. But it’s done. Redid the pan gasket and will be shocked if it leaks this time but with my luck, who knows.

Also, if I were to rewind and do this again, based on how this pan went on…I would torque it, then loosen, slightly separate, and torque all over again. That way I’d know the pan and gasket were in place, and pressed properly to the block before I’m ready to finalize.
