Leak around turbo housing w/ pictures!
Anyone one know the cause of this? Car is a 1987 NA to Tii swap s4.
i hadn’t started the car in over a week, I turn it on today and find my engine bay smoking. As soon as I see the liquid around the turbo housing I turn the car off.
I’ll remove the turbo and upload pictures of what I find, but can someone enlighten me as to how this can occur.
Thank you

What did the smoke smell like? Oil burning will have a nasty acrid stink, coolant has a sort of sweet smell that isn't as obnoxious. Cant really see from your pictures, but the oil supply line that goes to the top side of the turbo may be leaking oil onto the CHRA & turbine housing - those get hot quick when the engine is running, and would explain the smoke. Another possibility is the coolant line may be leaking and smoking in the same way - take a close look at the banjo fitting on the turbo's CHRA.

Seems like I’ll need a turbo rebuild.
On another note, I had another turbo rebuilt by Gpopshop a few years back. I installed it and ran it for maybe 10mins and It started smoking. I remember when I installed the turbo, I primed it cranking the engine over a few times without the EGI fuse in order for the rebuilt turbo to build oil pressure. I contacted Gpopshop and they advised me that it the oil must have been from an oil line dripping on the housing. Not what that looks like to me.
From what I’ve researched, when the turbo is rebuilt, companies may not reinstall a pressure valve in the oil lines??? Causing too much oil pressure making it leak.
Any thoughts?? i really don’t have luck with this.

if its green, isn't it coolant? if so the leak would be from the intake/something.
that turbine housing is pretty knackered though
