Default white smoke from left side only at wot?

Well,

I had this white smoke issue before with the turbos, figured out they needed a oil feed restrictor, so i installed a 0.9mm restrictor on both sides, and that seemed to solve the problem.

Now, just a week ago, the white smoke came back, except this time it seems to come out the left tail pipe ONLY (no x or h pipe).

The first thing that came to mind was a bad piston ring seal, but did a compression test on the motor and all cylinders were fine, readings for 5 random cylinders at 115, one cylinder at 120 and one at 130.

Where and what should i look for now?

PS. I dont know how the shop did the restrictors, but im guessing they welded the individual feeds and drilled a 0.9mm hole through, but again it cured the problem until now, assuming it is indeed turbo related.

What oil do you run? I run Delvac 15-40 diesel oil. If I run a 5-30 oil, my turbo will smoke.

Are they water cooled ball bearing turbos?
Man you have had sooo many issues with this whole project. This sucks. I hope you can get it straightened out. I think it might be time for some stateside help though.

I actually lost interest in the car, its now parked at home, waiting for someone to buy it off me and continue the project.

probably a good time to stop, and no one to blame other than the people who INSTALLED everything here locally, simply put they dont know ****.

At least I learnt my lesson, the hard way and have $80K worth of mods lost, + another $82K for the price of a new C6 Z06.

im running 0w-40 synthetic, but my assumption was the opposite since I thought the thicker oil would in turn generate more oil pressure and etc...

An oil change wont hurt, I can try that out.

Before you give up and take a hit, have someone like Jim go over the car....could be an easy fix.

I know the fixes are easy, and im not just saying that to make myself feel better, im taking a small break for the time being, if I get all exited about it again I might send the car to the states right away and make Jim post up all the funny things he finds lol.

check the play in the turbos shaft when our turbos start to get loose they start to smoke.
