I don't understand your point. Please elaborate.


You start putting sillycone on the rear main seal and you have already lost the battle. Never, EVER use that stuff on a rear main seal.

The very first consideration BEFORE a rear main seal goes in is dimensions of the seal groove, it must be on size and Round.

Secondly the rear seal retainer should be aligned with the groove in the block and a reference mark scribed on the pan rail surface for assembly. Alignment of the two seal halves is critical.

3rd, check the crank for dimension and surface finish. Knurling on some of the aftermarket cranks is way to aggressive from what I have seen. Never had an issue with a stock crank, knurled or not.

The point is, do your due diligence BEFORE slapping a seal in and slathering it with sillycone.

I posted a link for a seal that I have intimate knowledge on for nearly 30 years. If it leaks.... it won't be the seal.
