Hi, I have a 89 Chevy C2500 w/350 engine that I replaced the head gaskets on a few weeks ago. Today I have a lot of bubbles in the anti-freeze. Crap. When I replaced the head gaskets a few weeks ago the problem was between 4 and 6 cyl. where the head gasket just let go after several years. No problem, I thought, so I replaced all the gaskets, cleaned and inspected everything while doing it. The engine has 150,000 easy, well maintained miles, never hauled anything heavy. Everything looked great inside.
I am a custom gunsmith by trade and assembled everything meticulously. The head and block seemed very flat and an indicator only showed about .001" low between the 4 and 6 cylinders, and it is not leaking there now anyway. The engine didn't leak anti-freeze before replacing the head gaskets and I only have 200 - 300 miles on it since. I do know that I got the heads on without damaging the gaskets as I was extremely careful when I did it. There was no dirt either. Now it is leaking compression into the anti-freeze and the radiator shows quite a few bubbles, more than just a tiny leak in there somewhere.
I used a gasket set from NAPA and am now wondering if these gaskets are of poorer quality than they used to be? What are the best gaskets to use these days? I don't want to have to do this again! I used the NAPA HS7733PT-15 head gasket set which I believe is a Fel-Pro set.
Have these Fel-Pro sets been okay lately? What would you use?
Thanks!
Rick
