What's the name of the part that seals the manifold to the upper section of pipe?
Trying to order a new one, searched flange, donut, gasket, and keep getting different parts that don't look right.
I'm thinking so.. There is a connection there with something inside of it (like a gasket). The exhaust pipe is just sitting in the connection on the pass. side, so I can literally just pull it out of there. What do I have going on, you reckon?
The exhaust manifold has a flange the exhaust pipe has a flange, not sure about if it has 2 or 3 studs on the 97 truck. in between the 2 flanges is a gasket. with out seeing a pic of what you're talking about, if you can pull the exhaust pipe out of the flanges then I'd say you'll need to drop the pipe. if the bottom half of the flange is still on the manifold then you'll need to remove the flange and go get it re-welded to the exhaust pipe or just get a new pipe with flange attached. If this is not the case and you just have a gap between the 2 flanges you need to remove the nuts off the stud, (hopefully without snapping them), place a new gasket in between the flanges and re-tighten the nuts evenly around until everything is nice and tight. I know there's a torque spec but I don't have it.
The dark spot in/by the flange is the inside of the manifold
Yep...you lost the weld ...looks like it really didn't have one. Someone at the factory probably tac welded it and forgot to finish the job. So what you should do is # 1 drop the pipe and the flange to get welded. # 2 get a new exhaust pipe. # 3 what I would do...take it to a muffler shop and have them mig weld it. Probably $50 and your hands don't get dirty.
