Turbo drain line flowing freely? Probably so given that both sides appear clean. You may not be able to 100% tell whether the turbo seal is gone without pulling the housings.
Any play in the wheel?

I'll tell you that a few months back, mine was doing the EXACT same thing as yours - blue smoke at idle; looked like some whitish smoke with light revving. Had lots of in/out shaft play. The smart guys on here all told me it was the turbo. I didn't believe any of them, but still took their advice and got a "new" stock turbo from bison. Even when I removed the turbo, I STILL didn't believe the turbo was bad; there was no coking on the exhaust side. I FINALLY believed them when I put the new turbo on and "poof" - NO SMOKE!!
same thing happened to me and I put a new turbo on and no more smoke
 
Your probably burning oil in the exhaust, and its comming from no seals on the exhaust guides. THATS WHY YOUR PLUGS LOOK NORMAL. Buick DID NOT use seals on the exhaust valve guides. Remove the heads, have the guides machined for seals,have NEW exhaust valves installed WITHOUT the step in the stem. Your oil burning will end.:D
 
Am I going blind, [totally possible!], or are plugs #1 and 6 long reach plugs, and the other 4 are short??o_O
If so, WTF are you doing??
Look at the lower portion of those 2 plugs.. The threads are black...[Like they've been sticking into the combustion chamber.] They also look to be totally different tip projections.

Oh ya. Buy a camera. If you are going to mess w/ these cars, U R going to need 1!;)
Also, looks like those 2 plugs have been in the engine for a considerably longer time than the other 4...

Good eye, I looked at those pics a couple of times and completely missed that.

I'll be damned! I examined those plugs for awhile today CL and never caught that! I did notice the difference in coloration but not the length. Will be corrected tomorrow!

The forest for the trees thing ?

Damn Chuck !!! I did not even see that ...great eye for detail !!

I have only had 3 beers so its not the alcohol...LOL

After the compression test results is it safe to say its either the turbo or the valve seals? What would be the next logical step as far as diagnostics?

The advice that was given earlier to put in new plugs (the correct plugs), let it run for a while and read the new plugs gets my vote. A compression test will not rule out a oil ring problem. This would be far fetched but the expander could be overlapped.
 
run the engine without the air going thru the turbo.

pull the up pipe off the throttle body, unplug the MAF, start it up and let it run.

I suggest pulling the doghouse (elbow between intake and tb) and making sure its not saturated with oil. Really sounds like it could be pulling oil through the pcv line. I've seen that quite a few times and causes very similar issues
 
just capping off the PCV line would eliminate the PCV as the source of the oil.

Personally, I'm betting on intake valve seals.

Ok Gents, Here is where I'm at with this. The heads are coming off and are going to be machined to except exhaust seals and no, I'm not shooting in the dark or randomly replacing things. I have checked the turbo up and down EVERY pipe, hose, inlet, outlet, doghouse, etc. is bone dry with NO traces of oil. My diagnostics of this issue is complete and its time to start getting in to it. Thanks for all you guys insight and help. I will report back with my findings. One way or the other this smoking is going to stop. Thanks again!
 
would've been interesting to see if it smoked without the turbo. I would expect that would've eliminated a number of things.

Hoping after head work and seals it does not smoke, would hate for that to have been a waste of time. Although in the end likely not a bad thing either way.

take a close look at the intake seals when you are in there.

Bob
 
Do not use the stock exhaust valves with the step in the stem. You will need smooth stem replacement exhaust valves if the guides are cut for seals or the new seals will get torn up. Oil going down the exhaust valve guides will make it smoke bad at idle and then the smoke will clear up at higher RPM, and the plugs will stay fairly clean. Hope that's your problem.
 
This is what I was leading to with my initial question about the heads

I went they the same nonsense awhile ago, it was the seals

ive seen smoke out of tailpipe from a leaking valve cover that seeped into the exhaust manifold (#6)
