RE: Water Leak at Exhaust Manifold stud

[Rich Kinsley <rlkinsley@xxxxxxxxx>]

I have a poly instead of a wedge but I'm sure the problem exists in all 
of these. There is a lot of heat and I think it dries out the sealer. I 
did use the high temp good stuff too. I had the rear 'bolt' (in my case) 
spring a leak shortly after break in. Then after some racing a few years 
later the right front bolt starting spitting AF. I could just barely see 
the steam but heard it sizzle when it hit the headers. There's no way 
I'd remove those headers unless it was absolutely necessary. Just ask 
Paul Lenneman :-) So what I did was drain down the coolant and remove 
the bolt. clean it up and reseal it. I got pretty aggressive with the 
rear one because it happened again so on that one I gave it a dose of 
the black aviation sealer. That may bite me when I do have to remove it 
but for now it doesn't leak.
