I just replaced the heads on my 92 Chevy C1500 4.3 and in the process of reassembly, I found a gap between the intake manifold and the block. The gap is about the thickness of a nickel. Can I use “the right stuff” to plug the gap or is there something else I should do?
The heads bolted on with no problem and so did the intake manifold so I assume they are seated evenly. The replacement heads are from a salvage yard and had pressed in studs instead of screwed in studs, they also came with longer push rods but I kept the original shorter ones because I am assuming it was for a different cam or something. but otherwise they looked identical.
I noticed the gap after putting on new intake manifold gaskets and RTV… If I unbolt the intake manifold can I still use the same gaskets or do I have to buy a new pair?
Any thoughts appreciated. Thanks!
Thank you! That is a relief to hear. Wish I had known before I torqued everything down, my felpro set didn’t include a gasket piece for it.
As far as reusing the intake gaskets, should i scrape the rtv off both sides and reapply it?
Yes scrape the old rtv off as much as you can
Thanks!
