I did my intake gaskets this weekend and I made some major discoveries...
I bought Rock brand gaskets and they were some reinforced rubbery material between thin sheets of metal. looking at them I couldn't imagine how they could blow out, but I thought it would be revealed when I tore the engine apart.
Lo and behold when I got to the original gaskets there were rigid garbage plastic between metal. The thing had completely broken into pieces. I was shocked to think someone thought injection molded plastic would make a good gasket.
I was extra shocked to know I was quoted almost 1000 dollars to have them replaced knowing they would have put in those same crappy gaskets again. So the new gaskets seem VERY nice in comparison. So I recommend Rock gaskets and I'll post if I ever have any problems with the new set.
The other surprise is that there are only two bolts per side holding them in place. Over about a 16 inch span that seems very iffy. I would have guess at least four per side. Anyway, I thought someone with the erratic idle would benefit from this experience. I will post some pics and detail the fix in another post.
Peace,
gumby
