Oil pan gasket rant / question

The PO used a MASSIVE amount of (clear?) silicone on the oil pan gasket, it's taken me hours to clean the surface properly.

Rant over, is there some areas that I should be silicon on when I put the new gasket on? I have the one piece felpro, the surfaces are pretty good with no major dents or scratches. Any hints to put the gasket on? Should I run a really thin RTV to hold the gasket in the pan for install?

The RMS was a cakewalk compared to this silicone mess

Thanks! I'm frustrated right now, it's 30C outside and I wanna drive my jeep lol

Thought about you with the floods last week.

The site for RMS repair also details where to put the black RTV: http://www.neow.net/rms2.html

Basically, it's best to put a thin bead anywhere the oil pan curves - the front and back dips and their shoulders. It's possible the PO did that because that was the only way he could get it to seal - i.e. your oil pan is a little warped or your block hasn't got straight edges.

There is no need to use any sealant on the 1 piece felpro gasket or most gaskets for that matter. The gasket alone will seal as long as you have clean flat surfaces on both the oil pan and the block.

All I ever used was a bit of Avaition form a gasket to hold things in place for put'n the pan and stuff back on.

I believe the instructions that came with my felpro called for rtv at the rms and timing chain cover.
Its about the only thing that doesnt leak on mine.
