'02 Powerstroke 7.3L blowing oil out of dipstick and blue exhaust smoke
Is it using oil? My suspicion is you've torn an injector o-ring. That allows oil to mix with the fuel. You say blowing oil out the dipstick? Blow by on a diesel is normal. High compression and no positive crankcase ventilation. What you don't want to see is a puffing blow by strong enough to blow the oil cap off if you lay it upside down on the filler neck. If you are pressuring the crankcase enough to blow oil out the dipstick, you must have an obstruction in the passive crankcase vent (doghouse) in the driver's side valve cover or the tubing.

I wonder if clouds ever look down on us and say, "Hey, look - that one is shaped like an idiot!"
