blown header gaskets...

[eriemoto.]

is it possible that a bad motor mount, or broken downpipe bracket (holds dp to the block), can cause the gasket between the header primaries and the downpipe to keep blowing out?

do you have that

It possibly can, But the main problem is that the gaskets are cheap.

What I always used was the ultra copper RTV its like 8 bucks a tube and it works great. I normally just remove the old gaskets on the header and then put a generous amount between the 2 flanges and let it dry. Works great.

I don't see why the Header gasket would fail even if the DP isn't connected to the block. I mean its held in place w/ 9 bolts, so that should be more than enough to keep it sealed. In addition to the DP being connected to the Cat conv.

not talking about the header to block gasket, it's the header to downpipe gasket (3-bolt, triangular flange gasket).

do you have that

i'm missing the bracket, and replacing the mount soon. just want to know if i really need the bracket. i dont want to install the gasket, just to have it blow again because of the bracket missing

oh I thought you were talking about the head gasket, the one that bolts to the head w/ 9 bolts. Um.....I doubt that gasket would go bad, maybe it's not tightened down all the way?

i hope it's not warped, but we'll find out soon enough when i get the new gasket in.

the gaskets that i had on before worked fine for about a week, then they blew out again. going by that, i can assume it shouldn't be warped
