Usually...gasket = dry, no gasket = permatex. Keep in mind if you use goop on the gaskets, you will have to scape it all off next time you tear into that piece, if you keep'er that long. I do use permatex with the oil pan gasket, only because I've heard so many horror stories of warped pans leaking, and I am not crazy about that rear bearing cap transition, with packing, that the pan gasket has to seal. I also use permatex on the axle hub gasket, not the trumpet, just the hub, Thin coating between the backing plate, gasket, & hub, AFTER you have the shims figured out.. If you get a leak there, the oil is in your brakes. I do use copper coat on the head gasket too. Guess that's my 3 exceptions to the gasket=dry rule. I tore into my gov. housing once, the prev. mechanic used LOTS of blue permatex on it. There was ozzed-out permatex in all the bolt holes, studs, thrown all over the inside the gov. housing, from the crank assembly. A perfect example of why NOT to use permatex...use that stuff sparingly if you do use it! Yup, grease does help hold gaskets in place real good too, thicker the better... George
