I'm scratching my head on this one. I have a bad leak which has me putting around a quart of oil every 2 weeks in my 92 100 (w/ 164k) I just recently purchased. I complete washed down both underneath and top of engine and notice the leak is coming from the intake/cyl heads area; I've looked in-between intake and head and there is a pool. :huh: Are these 2.8L prone to oil leaks? Is there a crankcase 'flame trap' vent filter that needs replacement?? Or could it possible be a gasket?? I'm considering having the heads rebuilt with new uppper gaskets but if there is an alternative which one would know, I'd appriciate some advice on this one. Many thanks.
