One piece rear main seal
I was just wondering if anyone had tried or had success with the one piece rear main seal sold by Fast Fish. It’s a circular seal, which you cut through on one side & then work it around crankshaft

Never used one, but in my opinion that seems a ridiculous amount of money for only 1/2 solving a problem..

I’m not disagreeing with you on the price, just wondered if anyone had tried & what sort of result’s

Re: One piece rear main seal
The best solution is the One piece O rings they have on frauds and Chubbies - or even the conversions - but I have never seen the equivalent for a Mopar, and probably never will due to the size of Crankshaft flange.
It does seem to be a bit of a lottery with the 2 piece seals.
Where would you position the "Split"? On the Block area or on the retainer - as I have seen oil leak from both areas....

Re: One piece rear main seal
i have one from BOP engineering that i intend to try on my motor, just can't face pulling it all to bits again
what diameter is a big block seal surface. can't get that website to work from my work laptop
this sounds better than shortening a pontiac one which was my original plan, and with the inherent risk of puckering as i make a 3 inch seal 2.5 inch
its an experiment that has not happend yet
https://www.bopengineering.com/A_Pontia ... ls_1.shtml
pesterd this fella for years to do a run in 2.5 inch but he won't
pesterd mopar suppliers to have a look at the BOP site and get some made no luck
the split usually goes to the top
obviously same risk of a leak if the seal housing is wonky. but less risk of a problem at the split, blob of sealer or glue at both ends and it get clamped togther in the block by the application of the cap, success dicated by how sharp your razor is and how well you make the cut

Re: One piece rear main seal
often thought that if the cut lines on a rubber seal were biased in a direction oposite that of rotation we'd be in a better place... but... maybe too much thinking
