Leaking Again

UTGT · March 2nd, 2008, 10:19 PM

Well my headers are leaking again! Right now I have Percy's seal for good gaskets. A guy at a local shop told me to go back to the stock gaskets. I remember how thin they were and don't see them fixing the problem. This will be my 4th set of gaskets.
1.copper Horrible!
2. Percy's seal for good
3.graphite gaskets out of a hot rod magazine
4.Percy's seal for good with copper spray
What do ya'll think?

I reused my old gaskets and studs and everything has been great for over a year and half now.

are you sure nothing is cross threaded and its not flush, are they good name headers?

mystang0673 · March 2nd, 2008, 10:59 PM

how you tightening the bolts down? that does matter...

mbmconstruction00 · March 2nd, 2008, 11:02 PM

warped flanges would do it also

there BBK lt's with stage 8 bolts. i tightened them from the inside working out. I checked them and there all still tight.

mystang0673 · March 2nd, 2008, 11:22 PM

where they leakin from?

mbmconstruction00 · March 2nd, 2008, 11:23 PM

its gotta be the flanges then...do u know what thickness they are?

UTGT · March 3rd, 2008, 10:54 AM

i/m sure there leakin from the flange and there pretty thick. It sounds like its only the driver side, which is the on I've had a problem with the whole time. BBK even exchanged the header for me and it still leaks.

BBK's flange is 3/8" thick.
