To your deal. Lube between the bolt head and washer so the bolt can rotate so not to bind and twist the rubber.
My problem on mostly same subject.
1993 Eldorado 4.6 Northstar.
My Rubbers are worn out. Where can i get replacements? Anyone have part numbers?
"There is a service kit that includes all the bolts, washers and grommets as the kit was a retrofit kit for the early 93 Allante intake manifolds".
Also while pulling the injectors one of the metal clips that holds the wireing to injector just flew away
I was working with it and it just disappeared.
So i need one or two of those also.
