lots of smoke on boost.. help please, i have no ideas anymore

[blcknspo0ln]

I'll give you the facts:

6 bolt 8.3:1 ross / eagle rods / 1g head / MLS - 900 miles
PTE BB5031 turbo : 6,000 miles
660cc denso injectors
150 compression as of last night

DSMLink tune -
global : -33% and 195 deadtime
airflow - 50 mhz slider up 7%
(last i checked LTFT/STFT were +- 3% from zero)

boost 17 psi

I checked the intercooler pipe after the turbo and it's bone DRY, so I don't think it's the turbo. It also has no abnormal shaft play.

The smoking started happening right after I installed a greddy catch can. The way I routed it was valve cover - catch can - nipple on intake pipe. I also at the time reattached my PCV to a vacuum source on my manifold. BEFORE the installation that day, I was running a breather filter on the breather side and I capped off my PCV (Don't ask me why, I didn't know better; but the damn car ran fine..)

The car slightly smokes a blueish/white smoke (Lead to believe it's synthetic oil burning) at idle and increases like crazy on boost.

Since then, I have replaced the pcv, rechecked the lines on the breather side, and checked all settings on dsmlink. I'm running out of ideas! Anyone?

Was the head rebuilt or just resurfaced? -Maybe really bad valve stem seals?
Is there anything accumulating in the catch can?
Any coolant mixing with the oil? Maybe check the torque of your headstuds?
What AFR? Boost leak or unmetered air?

I would also pull your plugs to look for oil deposits and check your exhaust manifold for oil in the runners. Does it smoke all the time at idle or just a for a few minutes when you start the car?

If it happened after the catch can install it must be pcv related.
Or maybe your turbo is going bad.
