Well.. I had the truck ready to run today and just happened to have decided to drain a little oil out of the truck to see how it was after running the motor for a bit.. to make a long story short.. milky.

So I pulled the intake and spacers, mine are aluminum incidentally.. and the epoxy that I used to bond the spacers to the intake apparently could not take the heat and the coolant.

So to my question.. are you guys just using silicone in between the spacer and the intake or what... my other idea was to make a gasket for the spacer... we have some 1/16" or 1/32" silicone at work in sheets that I could use. Just curious as to what the rest of you are using... I read the article on Tyclone and this part of it was not real clear to me.

Other than that the truck runs great, thanks to BG and Nightdiver sending me some starter programs.

TIA

I'd use some gaskets or RTV myself. Gaskets first, but if they alter the angles/spacing too much, RTV...

I was thinking making some gaskets.. a little time consuming but for one off stuff.. no big deal.

I appreciate the response... looking forward to meeting both of you guys at the nats if you are there... hope to have the truck tuned and running right by them.

Hope to at least join the 12 second club.......... ;)

Well I don't have spacers or anything the intake was welded up and new holes drilled in the heads so the intake bolts up. I used the '96 up vortec gaskets (crappy plastic ones) and drilled new holes in them since they only have four holes, buy two sets of gaskets because they break easily when the drill catches the edge of the gasket. The gaskets lined up pretty good except for the drivers front corner and passenger rear corner, so I just used some of the Gm Silicone in a caulking tube and I have 300 miles on it and its holding really good so far, good luck with your fix.
