I have not even got to drive this car yet (building a 94 that was wrecked with 10K miles) and I smelled antifreeze and the lower hose is swelled and leaking under clamp) The car does not over heat however, I don't see antifreeze leaking by the head or out the exhaust. I am thinking I should just upgrade this gasket before spring anyway. (and I can powercoat my intake and valve covers yellow!!) What is the "book labor time" to replace this gasket, and what is the chrysler p/n for the "new and improved gasket"?
