Just went outside and ran the car at idle until it warmed up and started smoking. Took some vise grips and closed off the oil supply line to that turbo. Within 5-10 seconds the smoke drastically reduced, and in about 30 seconds or so it was gone. So I am definitely leaning towards the turbo oil being the cause, now I need to determine why.
The drain line is #10, and identical to the other side. It has a mandrel bent 90 degree fitting off the turbo and a 45 into the front of the oil pan, just under the rail. I have more 45's but there isn't clearance for that off the turbo I don't believe. Since the turbo was re-worked I don't think the issue is there.
Interesting deal, when I took the vise grips off, it takes 2-3 minutes or more for it to start smoking again. Seems like it takes that long to back up in the drain line all the way to the turbo, and then it's forced past the seal. Crimp it again, smoke stops and again another 3 minutes or so without smoke.
I've already checked the line for kinks and removed the fitting from the ATS pan, seems clear , nothing in the way of drainage. The crank turns clockwise so I'd think if that was the issue then the passenger side would be the one with a problem, if the oil off the crank was being shoved back up the drain line.
No final answer yet, but progress. Progress is good.
