Hello everyone. I’d like to share a problem my Supra is having in hopes that one of you could help steer me in the right direction. Every now and then on a semi aggressive down shift a white smoke cloud comes out of my exhaust. It smells like oil. Note I am catless. Car runs fine idles fine everything fine except when my car turns into a vape mod. There is visible oil on the hot part of the turbo near the bottom. Also note I do not see smoke coming from my engine bay. My warranty ends in 1 month. If this is a simple seal fix I’ll do it myself as I really don’t feel like spending a weekend making my car stock. Attached are photos. Thank you all for reading this and helping!

Also note the oil level isn’t going down. The coolant level also isn’t going down.

guess
If you're 100% sure it's the seals in the turbo that are leaking I'd swap whatever you have modded back to stock and just go in for warranty repair asap and take a gamble to see if they will cover it. If they deny it, I have a stock turbo sitting around here 3K miles I can sell it to you if you're interested. Turbo swaps are very easy to do.

I spent sometime yesterday making the car stock again and now the cloud of white smoke is gone. I think it’s gone because the oem downpipe is back in. I can still smell it but can’t see it. All this does is make my life harder trying to make Toyota replace stuff. Here are photos of the front and back of the turbo. It looks fine and here is a video of the smoke while it was catless.
