As thread title suggests.
Took car to mechanic, got it back with entire PCV vavle and S shaped hose attached to it missing. Mechanic says "we broke that sorry, just stuff a rag in the hole to stop the smoke"
I did that and drove around like that for a few days. Turbo slowly "died" after a day or two blowing smoke, no boost and farty whirry sound.
I thought It was a water line they didn't fit while flushing engine block etc that blew turbo but it seems it may have been the PCV?
No i did not take it back to them to demand I fix it. I haven't spoken to them for months. It did not even get a receipt since i have been using them for many years. I did not want to bother at the time but Only now i realized shit could that have been the reason the turbo blew?
I glued it back together and it doesnt smoke anymore but I dont trust it better get a new one? It may block oil draining out of turbo due to excessive pressure in crank, correct?
