Can anyone help me figure out what to do next to diagnose why my truck started blowing white smoke. I have only been able to get it to do it once the truck is up to temp and accelerating, it will start to smoke a little at idle and then leaves a pretty good cloud when I get going. Truck has about 64000 on it.
The smoke smells like exhaust, not oil or coolant. No codes, balance rates are good. I didn’t do PCV reroute but did install a catch can, it had maybe a teaspoon of oil in it. Oil is about 1/2 quart low at about 3500 miles. Coolant level is good. Truck starts, idles and runs fine and the mileage has been consistent. I switched between a sport tune and tow tune and it didn’t seem to change the amount of smoke.
You guys got any ideas I could try next?
