1994 stock turbo rebuild help!

Didn't see anything regarding your turbo being bad specifically - does it have excessive shaft play? Any gouges in the inside where the blade is, chunks of blade missing or dings? Your hat being off means you were building no boost, turbo could be fine

black oil with the IDI is perfectly normal. You can do a fresh oil change and dump the fresh oil and it'll probably be black
For oil filter upgrades, alot of guys use the FL-1995 oil filter - its for a power stroke but fits ours too.

Turbo as some play for sure but it does not seem to rub and it spins well, bearings feel smooth. Putting that hat on sure made a huge difference in power!! Haha I could tell it was on! The oil is milky (brand new) not sure if that means diesel or antifreeze. It leaks a lot of oil so that could mean my oil coolers bad right?

Also put a brand new stroker oil filter on.

these pigs leak oil a lot. Milky would hopefully be either head gaskets or oil cooler. Could be cavitation but hopefully not on a 94.

Oil pan could also be leaking too contributing to the mess, see if it has a cork gasket. if it does then you will have to take it off, clean it, and use only RTV no cork.

These are great engines after you work out the problems left by bad owners

It runs like a champ, started right up when no joke it was -10. I don't see oil in the radiator or bubbles coming up so I don't think its cavitation. It blows a lot of blue smoke when idles or crusing on the road, black and a lot of it if you stepped on it. So that may help you with some idea haha.

Check this out. It was a flat ground acceleration, downhill once it stopped smoking in the end. But see all that blue smoke in the middle of the video?

Video is Private, can't watch.

Blue smoke before adding the CDR back in means oil is burning if it doesn't ever go away, could be stuck rings causing it. Lots of black is over-fueling or air restriction.

I think Auto RX is the potion recommended around here for freeing up rings and cleaning up the oiling system.

Give this a read, some of its directly related some is just useful to know. Read the archives too:
