hey i have this small exhaust leak. can sometimes they leak or something, like a bolt backed off or something.

I hope the gasket didnt blow out, its a gasket from a federal mogul rebuild kit.
i have been running the new headers for about a week. ( not new, used but new to me.)

i dont have time to look today, i got prom later and cant get dirty

Yeah,it`s always worth retightning header bolts after running it.More like mandatory,just like the lower intake.

That's what I've always been told. Didn't know that about the lower intake though thanks for sharring that.

ensure all header bolts are tightened to 13-16 ft lbs if leak still exists and you know its coming from the header to block gasket replace it with a good quality gasket....

Click to expand...

It`s true,I had to retorque my lower intake 3 times before it stopped seeping coolant at the front headports.Each time you put the torque wrench on the bolts tighten down a little more...to where you tightened them down the last time.
Guess the gasket compresses.

That TMoss intake porting guy can verify this also.
