i think i have an exhaust leak but cant figure out where its coming from, i hear it and feel it on the back of the block on the passengers side of the car, i thought it was the headers but they are on there nice and tight, is there anywhere else it could be coming from around that area?

i dont think its quite as far down as the collector cause i can feel it around the header area, i really hope its not a gasket

Thats got to be it. header gaskets are notorious leakers. Use manifold gaskets, or soak the header gaskets in water for a couple hours before installing, then make sure to retorque after the first few heat cycles and about every oil change.Originally posted by bonnie&clyde View PostSlow moving projects

1 in a 100 chance, but on my 89 5.0 I had, I had BBK shorties on it and I had an exhaust leak as well. I could feel it around the headers, as if it was a gasket. I replaced gaskets and it still leaked. Ended up being a small pin sized hole in the weld. I patched it with some header/high temp cement and it worked like a charm.Comment

Hmmmm interesting u say by reaching back behind the block u feel it could it be a head or intake gasket?
Take a piece of hose and stick one side to your ear and run the otherwise all over your engine you can find a leak easy that way.
If it is head gaskets replace them and get stage 8 locking header bolts.
Or just tighten them again after a few times of heating them up after installationComment
