So. I decided today was the day to R&R my trunkside head and manifold, as well as my Y-pipe (Just delivered..)
Well before the post came, the sensor on the trunkside head (Near the tach filter. that goes into the head) The leads and connector were burnt and crumbled.

The Y-pipe that was supposedly good has a corroded O2 sensor in there, and the bottom flange has the captive nut ripped right out.
What now? I'm here in my driveway, motor torn down. Any change I can [i]try[i] to make this all work? Or should I just do what I can for today?

The good side.

Looks like you need a new one, or a person very good at welding. WHere the nut is missing it looks like rust has corroded long enough to make the metal too thin and weak. Not to mention evidence of the person who removed it hacking into the flange to cut the nut off.

I'd take it to a trusted exhaust shop and have them hack that off and weld on a new flange.

*edit, actually it probably would have been plenty strong enough, and could use a new nut, if the edge wasnt hacked off. That bent down lip that is missing used to give it strength.

Argh. Looks like my old Y-pipe is staying for now then, Y-pipe and manifold turned into Head, head gasket, dizzy O-ring, Manifold, ect.

Exhaust work is the worst for that! Especially if theres rust! Good luck.
You might get a 2nd opinion too in a bit, someone might chime in.

Trunkside manifold bolts are seized. I undertook this last time with the rear head.
My experience?

Prep a new head and manifold, just swap it out and junk the remains. So you're not down for more than a day or two because of flanges broken, bolts broken, ect.
