    does anybody have one that doesn't leak?

    I feel the cork gaskets today are just crap.. im really tempted to just seal it in place and be done..

    I don't have problems with mine leaking....make sure your oil pan gasket surface is flat and not dimpled around the bolt holes.

    Mine leaked continuously until I took the time to hammer out the bends in the pan. I had to make sure it wasn't overtightened when I put it back on to.

    I just use the aerosol form a gasket on oil pans and valve covers. I too became weary of chasing drips and tightening bolts. Relatively leak free now, for a Jeep.

    I used the 1600 series Fel Pro on my Offenhauser valve covers, after the 1400's leaked . It's kinda funny that I had to go to your Main. St. warehouse to get them. Any way, no leaks & I've used cork only , for a long time.
    Don't know for sure , but they may make the thicker gasket for your oil pan.? They are twice as thick as regular ones.

    Always make sure that both surfaces are clean & flat. Coat the pan sealing surface with High Tack. Stick on the gasket. Place it gasket side down on a flat surface bench or counter. Let it set for overnight. Next day install it snug bolts down, cross pattern style. Let it set for an hour and then TORQUE to specs. Do not over tighten.

    I'm not sure what the material is, but its dark with cork in it; not solid cork. The cork tends to compress, the take a set and starts weeping. This "other" cork-like stuff stays more compliant and seens to seal better.
    I usually glue mine onto the pan with "the right stuff" them loosely snug it to the block for the gasket goop to set overnight. For the final install, I smear some grease on the block side of the gasket and snug it on. If I know the pan isn't coming back of for a long time, it gets a light smear of the right stuff on the block side of the gasket.

    I just use whatever Fel Pro offers. I try to make sure I get flanged head bolts in the correct length wherever possible. Before installing, take a dinky little ball pen and tap pity tap tap the pan surface flat. Perhaps, if you feel artistic, you can dimple the holes toward the bolt head a bit. Be gentle and suave. Talk lovingly to the pan. It doesn't mean to leak. I use Indian Head gasket sealant from pan to gasket and gasket to block. If it's coming back off, just plan ahead on a new gasket. If it's coming back off, you will be miserable anyway, who cares about another gasket at that point? Tighten only with a nut driver, once when installing, again the next day, and again when you think of it when getting into bed in a week or two afterwards. Usually it works for me, but now and again a gremlin gets in that gasket and I get all miserable taking it down and scraping it off, wishing I had the foresight to get another gasket ahead of time.
