I see where the PCV house comes out of the front valve cover, goes to the throttle body, and then a few inches later is burnt. I've tried poking around and can't find anywhere for it to plug into. I think I see a trip to u pull it in my near future. Attached below is the EVAP component. Purge valve, I guess. Maybe. The other end (had a hose going somewhere, but it was crispy too. I plugged it with a door hinge pin and duct tape, because duct tape fixes everything.
A month later the car runs great. Better than ever, honestly. Turns out that aftermarket crap was causing the random backfiring and stalling that I was chasing for a while, which I think was what melted the inside of my cat. Gutted the cat, got a junkyard ignition control module and coils on it, and now she flies. Except with some MAP/MAF and IAT codes.
Funny thing is there's one exhaust leak remaining. Created by a big backfire popping one of the welded joints. Now people tell m1e it's the best sounding Buick Century ever. I've had people ask me what kind of exhaust I'm running. They're dismayed when I tell them gutted cat and leak two inches before the cat.
