I'm thankful for those that help others to learn
I have a 1991 Ranger that I replaced the 3.0 engine a few years ago... I had been and continue to be plagued with an exhaust manifold leak. Previously it just ticked.. (don't think the engine came with gaskets originally in there?)... after the engine swap (kept heads and machined the base of both heads but did NOT think to machine exhaust manifold mating surface) the problem started burning through a spark plug wire (w/swapped manifolds)... sooooo, I took original manifold on the one side that specifically had the burned plug boot and had it machined.... it evened the manifold out a bit but I feared there was still a little bit of "space" on the head's side when putting a straight edge against it... Two years later the gasket has failed again... I don't see myself pulling heads to solve this issue... would double gasketing the manifold do any better or what other suggestions??? some kind of hi temp gasket sealer in addition to gasket? Engine sounds so much nicer when not ticking but I can handle that if I have to and have put a small piece of sheet metal around the plug boot to insulate it from the escaping exhaust....
Thx! Brian
