I READ THE TOPICS AND COULD'NT FIND ANY HELP ON THIS. I PURCHASED A J30 INFINITI AND THERE WAS GAS DUMPING INTO THE OIL. I TOOK IT TO AN AUTO SHOP AND THEY REPLACED ALL 6 FUEL INJECTORS,REPLACED THE FUEL PUMP AND CHANGED THE OIL. I DROVE IT HOME AND IT WAS SMOKING LIKE CRAZY LOTS AND LOTS OF WHITE SMOKE COMING OUT OF THE TAILPIPE AND IT DID NOT STOP. WOULD IT BE ALOT OF BUILDUP OF GAS AND OIL IN THE EXAUST? ANY INFO YOU COULD GIVE ME ON THE FIRST THING TO CHECK PLEASE LET ME KNOW THANKS

So am I correct in assuming that the vehicle didn't smoke like that before the injectors where replaced? Residual oil or gas in the exhaust does not sound like the issue here. White or bluish smoke would be oil consumption. However, a blown head gasket or coolant in the combustion chamber will cause white smoke or actually steam and the exhaust will have a sweet smell to it. How well does the vehicle run? Is it rough at idle, cruising, or under a load. Are you getting crappy gas mileage? Are you loosing oil or coolant? With the vehicle cold, check the oil and coolant and top off as necessary, then go on a road test. Maybe the smoke will clear up or maybe you'll notice what fluids are evacuating the car. Too much gas from bad injectors will wash the rings down and cause oil consumption, poor compression, and gas in the oil. Gas in the oil will thin out the viscosity making it easier to seep past washed down rings and, worse yet, could wipe out crank bearings. Make sure the shop did actually change the oil. Good luck
