How to install a BOP Engineering One Piece rear main seal. Pontiac short block re-build, Part 5

How to install a BOP Engineering One Piece rear main seal.  Pontiac short block re-build, Part 5

Install a one piece rear main seal, for no leaks! The bearings are blue printed… Now it’s time to test fit our Crank, use plastigage to double check our oil clearance, install a one piece rear main seal from BOP Engineering, and finalize our crank installation. It doesn’t matter what engine you have, it’s the same process. If you missed it, check out the engine tear down episode… the bearings were toast! In this episode, “How to install your crank and BOP Engineering one piece rear main seal. Pontiac short block re-build, Part 5” We have to test fit our crank to make sure it doesn’t bind, check our oil clearance with plastigauge, install a @bopengineering rear main seal, and hopefully bolt it all together. Again, a big thank you to David Butler @Butler Performance for coaching me through what bearings to get, and what clearance targets to shoot for, which worked great!

Bill Thomsen says:

The hash marks on the crank for the Rear seal has to be machined off otherwise the hash mark will tear up that rear seal and will leak.

Robert Spadaro says:

Been considering this for my future Poncho build. The rope seals just aren't what they used to be when they outlawed the asbestos. Good video as always!

P.s. The small leak stopped in the distributor valley after I slathered on the RTV along the back edge of the valley pan like a madman lol. Like I said it's NOT pretty, haha. But at least it worked and I guess it was the valley pan after all. Thanks again for the help!

Terry Petty says:

S0, you torqued the main caps to 1-4 at 100 lbs, and the rear at 110 lbs, right? Did I hear you right ?

JETGuitars says:

Found this vid from one of the Facebook groups that you posted it in. Thanks for the information. You got a sub from me.

Jason Shirkey says:

Great job on the install I’m currently building one my self but at 15 I’m pretty sure I read something about you can’t run a one or two piece seal on a stock crank because of the notches on the crank for the old rope seal but I’m not sure which one you have and I’m probably wrong but looks great keep up the good work

tanner smith says:

The day is. Gonna come where I rewatch All of your videos when rebuilding my P 400 bet.

Trans Am 455 says:

Man this is an exciting build Mike. I love LS series engine builds but there nothing like that old school Pontiac n Chevy.

Chris Lincoln says:

Doing the 1 piece oil pan gasket from BOP too?

Mads Jensen says:

iam sorry to say it, but thats not how you put that seal on… chance is big thats not going to seal up.

Steve Brown says:

I use the BOP 1 pc seal as well. Works great and zero leaks on my motor so far.

mobiltans says:

greg schultz says:
