* Nothing * short of replacing gaskets will do any good.
Smear anything you want on the outside, the inside leak will ruin your
engine. As for pour it in radiator sealer,
it won't congeal [ sp ? ] in the oil rich atsmosphere of the manifold
valley. Change gaskets, post back if you want helpful advice on * that *
fun job. Change oil, use an engine flush [ Gumout makes an excellent one ]
change oil again. Antifreeze forms some awful sludge that will shorten your
engine's life. Might want to consider a
better manifold to justify the labor, or stuff up the heat crossover with
aluminum foil for better highway performance. Label hoses / wires, and
photograph before dissassembly. I'd rather pay for [ one way or the
other ] an intake R + R, than an engine R + R.
