340 rear main seal leak/gush

Dan, I’m one of those guys who’d tell you that not all of us clock the seal offset like that.

You need to learn to fit the rear seal rather than offset it.

Think of that seal like a bearing and then tell me if you’d ever offset a main bearing like that and why you’d do it.

Well Turk, It's a seal not a bearing. I've put together 11 engines since 2009. Mine and some friends. Always used a Superfomance "pink" rear seal and always clocked them 3/8 offset.
Not one has ever leaked a drop. Way back then, Rick @ Superformance told me that's the way ya do it. So I considered his advice gospel. I was brand new to Mopar.
