i just replaced my rubber oil return line with a steel braided one and the guy added oil to my car and spilled some on top of my motor and it ran down into where my plugs are and into the turbo where the inake pipe goes, now my car smokes out of my exhaust. could oil have gotten past my plugs or suck thru my turbo and made this happen, i wiped the oil off the turbo and when i drove it back hope and checked there was a little more oil in the same spot. the car did not smoke at all before.
