Oh crap, I didn't use the flat part against the seal, I used the lip part. I figured it was designed like that so it wouldn't touch the rubber. Is that a problem?

I should have posted the pics up earlier.

I'm not taking pics. I looked at the old rubber, and it's thick and strong. No way I damaged it installing it the way I did.
However, the manual explicitly says in bold lettering, do Not use lubricants during installation. And That the soap and water helps the seal bond to the case. I'm afraid the only "bonding" gonna be going on under my truck is a puddle of oil bonding to the ground after it leaks out of my bellhousing. So I went to town and bought a new seal. Lessons learned...tommymonza and Rideandrepair Thank this. -

I really don’t know, but I think they leak around the crank, not the outer sleeve side. May not be a big deal. I understand it’s a big labor job, if it does though. My Detroit required a special installer with spacers, different sizes for front and rear seals. Luckily I borrowed one from a local shop. After a few told me it will leak otherwise.Detroits new style green seal/ sleeve rides on center of sleeve, sleeve sticks out, instead of being flush, like the old style orange ones.

As said before, think your doing a helluva job, going the extra effort to make sure its right.
And thanks to the guys that know and are helping!!!Last edited: Dec 8, 2020

This seal was pushed out and damaged from to much crankcase pressure.
They are not as robust as you think.Attached Files:
