My wife's 93 J30 has an exhuast leak coming from the driver's side manifold. I just bought a new manifold, gasket to go on head, and gasket to go to rear exhuast pipe.

My question is, is there any tips or hints from anyone that has done this before on this motor? I have been soaking the nuts in PB Plaster for several weeks now and I know that parts like that come apart better when they are still hot. Besides that what should I be looking for?

TIA,
