Rear main seal leak and need advice

[Gunner1]

Guide studs installed

You can see how far off both style retainers can bee with the seals at the 9 and 3

I have had perfect luck installing the seals at the 12 and 6 - Zero drips on my Stroker motor , and two other 440 s that I replaced the rear main seal recently

This motor was line honed using a 440 Source Stroker Kit and Billet Steel Main Caps

Line Honeing or line boring both can move the crank centerline up in the block. Depending on how much material was removed our of the block. If the operator removed only .005 from the bearing saddles then the RMS is now .005 out of line. Usually I always tried to remove as little as possible just for that reason.
