My bet is the turbo or its associated parts like the drain line has a hole. I wouldn't run anything in the diesel or the oil until you do a leak down and compression tests to see if it is the rings/valves.
I'd pull the elbow between the turbo and intake to check for leaking turbo seals, plus do the compression/leakdown tests.

Unless you get really lucky and find a bad turbo seal you will need to pull the head, jerk the pan, and change the rings. It should only take you about 8 hours.

Bad turbo seals can blow a bit of oil... I'm putting 1qt/350mi into one of my Jettas.

Yup. it only smokes blue on an engine with a throttle plate or restricted intake tract.

Before i replaced the turbo [may 2012] it would lay a big blue cloud on full throttle.

I, admittedly foolishly, swapped a really high mile TD to synthetic years ago and it would most assuredly smoke blue at idle and under hard acceleration. Wasn't there the week before on dino and was gone a week after back on dino. It was wore the heck out. :-)

who did the turbo? I stated earlier that I thought it could be somewhere in the turbo parts.

Turbo was a re-con done by a UK company,no play in the shaft and no oil in the compressor,so you dont think the worn rings are the cause of the very low compression?

Possible, but I had one that had 240 -260 in the holes and it didn't use oil it just started hard.

Thanks,well it starts instantly [like a direct injection engine] just runs a little rough if i dont have the cold start pulled out.
I plan on replacing the crank oil seal [flywheel end].
Thanks for all the advice.
