Hey Guys, good question !!-what can we do about the lower intake gaskets
As I've stated before, mine were totally wasted
I'm including this link to show you a picture I took. (the picture is very large, so you'll have to scroll around to see it all.) Click this link to view detailed image:
I have a couple of questions for you: (-all thoughts and opinions welcomed)
1. What the heck are those notches for in the coolant ports ?? The new blue gasket is from the set I got from the GM dealer, saying that they "improved design."
If you scroll clear over to the right, you'll notice that those dumb notched areas are where the worst failure was on my 1999. (had never been apart, as far as I could tell) Now I may be missing something obvious here, but please "give me a clue !!"
2. Why are the raised silicone beads smaller on the Fel-Pro set? (the red ones on the left) AND notice that the Fel-Pro gaskets certainly do not have those notches. Hmmmmm
, I wonder why that is ? (-at least I think that the general rule is that red silicone is for higher temperatures than blue,,)
I remember someone saying they felt that the Fel-Pro gaskets were even worse than the GM'*. Heck, I don't know. I did use the Fel-Pro'*, but now I wonder if I should have used the GM'*. I just was totally bothered by those dumb notches. And for what it is worth, I have used Fel-Pro sets on most all of the small block Chevy'* I have built, and have been TOTALLY impressed with them. (-what is even more interesting, think of the thousands and thousands of small block chevys running around out there with aftermarket aluminum intake manifolds on iron heads and blocks, being abused daily, and never failing,,,,)
Oh yes, just for fun, scroll the picture clear up to the top right, and see the one coolant port that was totally plugged with nasty "Death-Cool" crap. Granted, it was the one which is blocked off by the manifold, but the "death-cool" corrosion was at least one inch deep into the cylinder head too. It took a lot of screwdriver and shop vac time to get that crap out.
GEEEEEEZZZZZ GM, What have you done to your faithful followers
