Subject: Leaking Header gasket
IP: Logged

Message:
Hi sorry to cross post. Posted on V6 forum, so far no response. I give this board a try. Thanks in advance.
I have the JBA headers for the 3.9 V6. The problem I am having is that the gaskets always leak. Anybody know of a better way to seal the headers. I am using the Carquest gaskets without any type of sealant. Do you know of other gaskets for the v6? What about a method to use (2) gaskets instead of one (super glue together)? Any suggestions?

Header leaks are pretty common. The first thing to look for is a warped flange. If it always leaks at the same place, that's the usual problem. To find it, you'll have to pull the header and put a straight edge across the sealing surface. A good machine shop can dress it to flat again.

It it's leaking in different places, it's a gasket problem. I like copper gaskets and Stage 8 bolts.

I'm not real familier with the 3.9, so could be blowing smoke here. But you might be able to cut down a V8 gasket to fit correctly.

I've got a 3.9 and have had JBA headers for 5 years and no leaks.
Make sure you tighten them down good on initial install. And
recheck them once a week. Sometimes they do need a second
or third tightening. Try lock washers maybe if that don't work. I
guess two gaskets might work if your headers aren't as smooth
as the head is at the mating area.

last resort try running two gaskets instead of one, they might make up the difference...
