while doing my engine swap i had a few of what could have been cracks in the exhaust manifold welded. now that the engine is done and running good it sounds like a leak in the exhaust manifold. when i took the manifold off and unbolted it to the exhaust down pipe i didnt notice if there was a gasket of some sorts that maybe i didnt reinstall.

so is there a gasket or something where the manifold bolts to the exhaust pipe that im missing and is now leaking?

alright well i saw in the back of quadratrac there is a gasket. but when i look at az or adavanced online i cant find one.
so new question where do i get one of these not buying it online?

I got mine at autozone. they had one on the shelf.

They may not list them online, call or stop by and ask. Napa would have it as well.

Right on! Thanks guys. Hopefully this solves my problem which I think it will.
