ok so i had dc 421 headers and now im selling the car so i put the stock headers back on and when i start the car and let it idle for a few minutes it starts to smoke from between the headers and the block. i torqued it to like 20 pounds so what do you guys think?

tightened from the inside out?

your gasket??

Spect2K3

sounds like the gasket to me!

yeah, you need a new oem exhaust manifold gasket.

ya i know i didnt look past that i got a new manifold gasket and it still smokes

draxcaliber

how is it performing? could there be some something in the header blocking the exhaust and causing it to come out between the header and manifold?

WD-40 burning? :D No?

^^^ very well could be... how long was the stocker off? maybe it had something on it, or in it?

No matter what way you cut it it's either something burning off or the gasket isn't making a good seal. If it were something burning off then if would go away after a few minute. Just my $.02

What was the outcome?

you prolly stored it where some oil got on it depends where its leakin youd hear some sputterin if there was an exhaust leak.... id wait it out for alil see if it goes away.. if you really wanted to take it off and just spray some degreaser on it let it dry and put it on see if it smokes again..

Thats my guess. Mine did it to but i used PB blaster, which they claim NEVER evaporates, so it had to be burned off.
