Any and all suggestions welcome...
How much oil are you burning between oil changes? How do the plugs look? I'd check compression on each cylinder. If everything is good, might be the turbos. How many miles you got on her?
X2 on ^^^ ! There is an updated PCV System oil separator as per TSB. Z
How's the oil level?
13+ TSB can be found below.

120,000 miles. Oil is in the middle of the hashes on the dipstick. The CAC has 1/4" of crud. All plugs are very clean and compression is within 10% from cylinder to cylinder.
Runs like a champ.
Does anyone know the part number for the oil separator & PCV?
I would rather just replace it than put the car back to stock and bring it to the dealer.
SERVICE PROCEDURE
1. Remove the positive crankcase ventilation (PCV) Valve. Refer to Workshop Manual (WSM), Section 303-08.

a. No - this article does not apply refer to WSM, Section 303-00 for Excessive Engine Oil Consumption.
b. Yes - proceed to Step 3.

Thank you!!!
I will take the separator off to see if it is gunked up with oil.
I used a 8mm socket to remove the two bolts followed by a retaining clip in the back of oil Sep! Z

ZSHO,
Was your separator considerably oily?
Does the TSB including valve cover remedy this?

The rear valve cover and oil Separator plus PCV were replaced under warranty a couple years back as per TSB.
They found evidence of oil inside the crankcase vent oil Separator accompanied by oil around the rear valve cover gasket.
The TSB did address my concerns with the excessive oil smoking coming from the tailpipe.

This is what my oil separator looks like.
Might be time for the TSB Service.

GB do you have a wider screen shot of the area in question! Thanks. Z
I was curious if you have any updates! Z
Put on UPR catch can and changed the PCV valve / separator.
No more smoke...
I will be changing my oil this weekend and draining the catch can.
Not sure what the culprit was but the smoke is gone!
GB. Is your concern of blue smoke after WOT still resolved. I have the same problem since I went to straight pipes and after a good pull spraying the Methanol when I come to a stop I have blue smoke. Oil level never drops, spark plugs are clean. I did the TSB three years ago for the oil separator/PCV valve, and valve cover. I had a couple of JLT catch cans and installed them for now. I just went into parts and ordered a new oil separator/PCV. I think it is the PCV system that is allowing oil into the intake and when you are WOT the methanol is cleaning and washing down the oil that is in the intake. when you come to a stop it is still burning the oil that is still in the system. Just my $.02
I had one of my air filters come off the turbo inlet tube. This created less vacuum for the PCV system during boost so I had more blowby.
Unfortunately I put a catch can on at the same time so I don't know if it was one or the other.
I am sure they both helped the situation.
