Im currently decatted and had a leak on the oil turbo feed which made the car smoke theough the muffler. Just got that fixed and its now smoking even worse!

I just had the engine rebuilt due to a piston goving up on life.

Any oil leaks that could cause this? Turbo loads just fine and car gives me 0 codes

 

Are you sure it's not residual from the previous leak?

 

If you're lucky, the smoke will be from residual oil in the exhaust system --- from the blown "oil turbo feed". It takes a few miles to burn out previously leaked oil.

If you're not lucky, your re-builder screwed up, and you have a new problem. Compression or leak-down test? Break-in oil was synthetic and didn't allow a good ring seal? Is smoke from oil or coolant --- blue or white? Plugged turbo oil return line? My turbo recently gave up and pumped oil everywhere --- intake and exhaust. Check your turbo air compression chamber by removing the air inlet hose --- should be dry, no puddles. I'm having a PCV issue that causes oil based smoke, probably caused by mods --- severity is subjective.

Lotsa possibilities. For useful help, provide us with all kinds of significant info --- model year, mileage, mods, major repair history?

 

I had this happen after replacing my turbo oil line, it continued smoking for a week or so then stopped.

 

All the guys at the local mini scene agree that its oil seeping through a bad seal inside the turbo :(

got an extra turbine while mine gets fixed. Anyone here that has a stock turbine and has bore it to a bigger diameter?

 

Bore it out for a larger compressor no, but you can buy one with a larger turbo. JMTC has turbochargers that are 7mm larger and can come ported.
