It was definitely the wastegate. It is back to pulling nice and hard. And spooling way faster.
Pulled the turbo/manifold. No oil that we can see. Ports look clean too. Will take some pictures.
Next will be the intake manifold, and look down the plug holes. And if no oil then I have no idea, and will keep driving it.
Maybe check the exhaust too.

Intake manifold is off. It has a **** ton of carbon build up because I didn't clean it before install. But no smoking gun.
Some oil on all the port walls. But the valves appear to be clean. I swabbed them all with a qtip and nothing.
Using the boroscope there might be a wet spot on cylinder 4 but it's really hard to tell with such a shitty camera. I'll attach a picture anyways.
So I shut the car off while it was smoking, and can't find oil anywhere except the port walls, intake manifold, and maybe on piston 4.
This sucks.
In good news. Albert made me a baller new injector harness.

Broke my exhaust clamp downpipe brace. We'll see if the replacement lasts any longer.
Hacked together my leakdown tester to use on the bottom port of my wastegate. This is a fresh new bushing.

Interested to see how it deteriorates.
