All,
I've been tracking down a coolant leak on my '82 4.2L CJ-8 for the past few months and have finally found it (after replacing every other component first, of course): one of the studs used for aligning the manifolds fell out. There's a fine mist of coolant that's coming out of the hole where the stud normally is, at least until the engine gets hot - usage is about a quart every 3000 miles. I can't find anything about removing or replacing this stud in the factory service manual, although I admit I haven't looked thoroughly. How is it "installed"? Is this something that's pressed in? Will I have to take the head off to fix this? If so, maybe it's to upgrade to the 4.0 head; the Mopar fuel injection kit's already on there.
Thanks, Michael
