Default downpipe/header

okay on thursday i was doing an oil pan gasket and new oil pan right.. and i had to drop downpipe transmission plate and subframe.. well after reassmebly everything 3.5hrs later i can hear a leak and smell it right where the downpipe meets up to the header.. is there a gasket i forgot to put don't think it has one. i know the other end that goes to the cat has a gasket.. anyways the 3 14mm bolts are freaking tight so i don't get it.. is it a big deal if its leaking a little will i run rich?

Yes, there is a gasket in the downpipe between the downpipe and manifold. It would be ideal to remove it and install a new gasket to fix it.

If it's stock...it's not a header...it's an exhaust manifold...

header/exhaust manifold same thing..


because header would have a gasket and manifold wouldn't so i'm pretty sure theres no gasket.. so my leak must be somewhere else..

your 02 sensor might get some bad readings. and everything around the leak be exposed to more heat than normal.
