Update...
First, I have determined that this car is very, very hard to prime...even with a mighty vac. With a mighty-vac, I am finally able to prime it, and even then, it takes a good deal of cranking. The fuel pump mystery in this car definitely is preventing the pump from being able to pull any fuel. I bought two cans of diesel purge and ran spare hoses into a different container and primed and primed with the mighty-vac. Cranked and cranked and finally it hit and idled. I didn't rev it, but there was throttle response. It has an occasional 'jerk' or bump in the idle, but never stumbles, and maintains an idle around 930. Light throttle is very smooth. Nothing coming out of the charge pipe initially. Exhaust relatively clear, but the car is pretty loud up front...like maybe a flex pipe...if there is one on a TDI. IDK yet. The car continued to idle really nicely with the recurring 'hicup' type bump here and there. The engine rocks noticeably in the engine bay each time the 'hicup' occurs. At this point, all piping was connected except for the charge pipe. After several minutes of idle, I saw one black drop of oil form on the open end of the pipe, but nothing more. After about 10 minutes of idling, with a cheap obd2 scanner temp reading of 156f, I started smelling coolant, and noticed a vapor coming out of the charge pipe. It was not oil vapor. I put white paper towel under the open end of the pipe, and as the occasional oil drop would hit the paper, there would be a wet, pinkish orange wet area around it, all the while, there was a little bit of fog coming from the charge pipe, and it smelled of coolant. No coolant on the dipstick, some fog coming from the valve cover with the 'puck' removed. Altogether the car ran for 15 minutes or so, and I finally shut it off.
So, at this point, it appears that there is 'some' oil in the charge pipe, whether it's engine blowby, or turbo seals, and there is coolant, and I think that is more concerning to me. Where does coolant in the charge pipe come from?
