I have been using Felpro one piece pan gaskets due to easy in chassis installation and have always had a leak/seap from the front lip seal.I use the thick front seal type gasket and have an aftermarket cast timing cover.Is there a better sealing gasket available fron anybody?I have tried stock pans,Milodon,Canton and now Kevco pans over the years and always the came issue.I have tried dry install,with silicone and withGM silicone for intake end seals.Any suggestions or opinions on how to solve this??I do this for a living and the only one I have had this much trouble with is my own:mad:

i've fitted one piece rubber pan gaskets in the car a few times,
all i've ever done is thoroughly clean the block and pan with brake cleaner,
only sealant i use is a small dab of black RTV in the 2 front and rear corners,
gaskets i use are the regular victor reinz (spelling?)

I use the 1 piece blue fel pro and have used it on several other builds. I always use gray silicone and have never had a leak from the gasket. I have reused these gaskets several times. I have never had any luck out of the cheaper rubber gaskets. I use just a light coat on the pan rails and use a heavier coat on the ends mainly in the corners. I have used them on stock, Moroso and Hamburger's oil pans.

I use the Felpro 2 piece and black silicone, but I've heard the gray silicone is even better. I use Permatex high-tac or contact cement to adhere the side rail gaskets to the block then install the rubber end seals in the block and then run a bead of Permatex ultra black or gray sealant around the entire gasket surface and attach the pan. Remember to pull down evenly as you go. IMO, it's important to use Permatex or contact cement on the block to keep the gasket from squishing out when tightening down.

I am getting ready to change mine. I have a hamburger pan and I bought a milidon 1 piece gasket yesterday. I hope it doesn't leak!
