One more exhaust manifold question
So thought it was the manifold gasket but no...should have just replaced the manifold anyways but too late now. Plus I'm now a pro at taking it all apart. Does the manifold tend to fail at the cylinder back by the firewall often? That is where I see exhaust coming from especially when i lay on the gas. Most of the posts tend to say it cracks where the 2 pipes collect by the exhaust pipe, but I also see a lot of manifolds with the flex pipes on the 1st and last cylinders. Just want to check so I don't do triple work.

Yes some of the manifolds are notorious for cracking at the collector.. You should find a hair line crack or bigger around that area.. Its in the exact place you describe. next to the firewall
If you want run some seafoam through ur system and see where the smoke comes out from..

I did again last night to make sure that's where it was still leaking from. All I can see is a big puff of exhaust from around that area when I hit the gas. Intakes are clean now since I already pulled them off, so I cleaned the ***** out of them, so not much smoke coming out with the seafoam. But good to know I guess that it is common. looks like its where the flange or whatever it's called is welded to the pipe, the piece that is against the head.

Made by Dorman I guess, has the flex pipes. Circled where it looks like the leak is at. hopefully you can see the pic.
