Really need some insight here.
Had an issue where on deceleration, I would get heavy blowby, thick white smoke that would linger behind me and come out the exhaust. This was after a pull and hard acceleration. This would eat up my oil level and cause issues, had a lot of this in the summer time, I just didint think anything of it and just kept topping off the oil as a typical teenager would (lol). Fast forward a bit, I had it happen again, but this time it ended up blowing the turbo. Shop stated it was due to extremely low oil levels. Quick $2,600 right there, lesson learned. Drove pretty mildly after it was replaced, some fun here and there as its winter time in michigan, made sure I check oil weekly and topped up as needed. 2 weeks goes by and the exact same thing happens, I accelerate from a stop sign pretty fast as another car was pulling up at the same time as me, and as I put on the breaks a ton of smoke came out, and loss power, car wouldnt turn on etc. Shop stated it was a blown turbo again, and was either low oil, too much boost pressure or faulty turbo.
I don't know what the issue is, If its PCV valve, ive done some reading and it seems like maybe this is the issue? Im not really sure where to go from here. not sure if it matters but i have the o2 sensor in the engine bay unplugged as EQT forum and many places recommended to do so if tuned so you dont run rich with having an aftermarket downpipe.
If I missed anything please let me know, and ask it below so I can answer, just want to know what my next step is.
