SO yeah.

After going through tons of headaches and countless skinned knuckles and fingers I finally finished the swap!

Here's some highlights of the events:

Pulled VC to paint and clean up. Next day (not done yet) was forced to push car back outside and let sit till we could work on it again. Covered the head in multiple rags and towels (not my call/wasnt my decision i would have used plastic and tape.)

It the snowed later that night. Couldnt move the car around for a few days so it sat for around about 4 days. When i went back to put the VC on i noticed light surface rust on the rear lobes of the cams. Cleaned it off nicely with a scotch green and some PB blaster.....put the VC back on and didnt think much more about it.

Fast forward 2 months (dealing with bullshit and finding a good place i could work on it) i finally finshed the swap. Went to put oil in the car and figured "ya know what, im going to take out the drain plug and see if anything is in there. (already assumed that the mech who first inspected the motor did so and checked inside)

OUT POURS FUCKING 3.5 QTS OF FUCKING WATER. YES.....WATER.....and then around a quart of this disgusting oily sludge gray shit and the weeeee bit of clean oil i poured ontop of the cams.

LUCKILY the water only sat in the pan and was not touching the crank or bearings (pulled the lower pan off and inspected it...was cleanish) and sat pretty much submerged in the oily sludge crap protecting it from rusting over. The cyl walls were clean and i could still see the crosshatching.

******Main reason for posting/Video Below******
I finally started it last night and it instantly (after priming) fired right up!! No hiccups, no hesitation, no long cranking...it just instantly right up!!

Heres my few issues now:

1. Car idles at like 9.8 to 10.3 afr at all times and at 2k rpm. I havent revved it up because of the noise im hearing near the CAS (we'll get to in a sec) It can run for like 45 seconds pretty good, and then starts fouling the plugs/ blowing smoke. I cant tell what colour that smoke it since it's 23 degree's here and it looks really white..in the vid its fine, but about 5 seconds after i stopped recording it starting blowing smoke so i shut it down.

2. I discovered the car has aftermarket mystery cams installed (i figured it would anyway seeing as it has 550's, the turbo kit, and z32 maf) so could they cause the idle to be this lumpy?? Maybe its misfiring? Bad coilpack? Maybe its fouling the plugs because of a stuck injector?

3. Car holds -14 vac which seems pretty good? Maybe its a vac leak somewhere??

4.That GOD AWFUL slapping noise i hear coming from the upper VC/front cover/CAS area. It sorta sounds like the chain slapping against something intermittently. Its most definitely NOT the VTC noise so often heard. I spent like 2 hours watching youtube vids before posting here so maybe y'all can recognize it? Maybe its a bad bearing or some damage caused by the water?? All i know is its really loud.

I would love to keep the motor running and check things over more but after about 45 seconds-minute it fouls the plugs and blows smoke. at first its perfectly fine...just rich as you can see. I figured that even at 10 afr it wouldnt foul the plugs so fast.

Thanks y'all! Whomever gives me a working solution will get paypal money! I just want this to be driveable enough to make it too the tuner/dyno, otherwise im going to have to send out my ecu to enthalpy or something. thanks.
