lets talk pan gaskets and rear main seals

I've never had much problem, the usual Fel Pro or Victor gaskets. I do NOT use the end seals either in the pan or intake.

CLEAN

Get the pan rails STRAIGHT, tap out any holes that have been dimpled form overtightening.

CLEAN

I can't remember "Hi tach?" Permatex is what I use, it s the dark read "soupy" stuff, glue the gaskets to the block, assuming it's inverted on the stand. Take the time to get them well aligned, use a few bolts, etc

When they are "tacked" in place, apply the last coats to the pan and gasket, then lay a huge bead of RTV front/ rear, and set the pan in place. DO NOT overtighten. If you're a big guy, use a 1/4" drive set. Or hold your 3/8 drive up around the head, and tighten criss--cross front to rear a little at a time.

As soon as you get it "seated" take your finger or towel, and smooth the bead into the gap, take care to make sure it's completely filled

Then a final tightening if necessary, and do not fill or start for 48 hrs if you can afford it
