Well I broke it so woopty doo.

Start 1: ran it for only 10 seconds or so, open headers. Just wanted to see where I was before putting on the full exhaust. All seemed fine.

Start 2, we got the exhaust on. I can now tell that its running very choppy. There is smoke coming out the tailpipe and mid pipe - header connection. Need to tighten. The headers are also smoking, understandable, burning off oil from hands and probably small exhaust leak. After a while the idle seems to smooth out (but it is not smooth, just less choppy) and it made an intermittent squealing noise that was not the belt. It didn't come from the belts and it simply just wasn't belt noise I don't think. It was a fade in/fade out squeal. Came from under the valve cover. It happened about 3 times and I gave the car is slight rev to 1500 Rpms and I got the squeal again. The sound passed on its own and only lasted for like 4 secs. Then I decided to flip the lights so I can see and the car shuts down for like .7 secs and jumps back to life. There is also a weird smell inside the car coming from the AC vents, its all the smoke getting inside.

Start 3, the squealing noise hasn't come back, however the idle is rougher than it was, the car is a little warmer nw and the noises from inside the valve cover are more prominent. From rubbing noises, to clicking and ticking noises, to what I could almost describe as rubbing two high friction surfaces against each other. It was a steady sound that came and went. Then I sat in the car for probably 20 seconds and it started to sound like s truck and shake so I shut it off and went home.

I don't know anything about this stuff. I cannot diagnose any issues. I don't have time to go read tonight. I am completely lost and exhausted, getting to this point has been a total pain in the ass and rewarding in no way whatsoever. And I probably just fucked up the whole thing.
