Re: 7.3 white smoke

Okay thanks for the imput guys..Symptons: Runs fine, doesent sound any different and no loss in power. Under hard accell it blows white mixed with black and when its in neutral if i rev it a puff of white comes out with some black. Fuel bowl was clean and so was the filter. I did notice this was only on the higher tuner setting..When i was on stock setting since it doesent blow any black smoke, doesent blow any white either

Re: 7.3 white smoke

with the truck running, at full operating temperature...

unscrew the oil fill cap from the passenger side valve cover...if it has a steady haze (oily mist) then you're in not bad shape...

however...if there is a puff, puff, puff. (as if there is moderate pressure behind it)...then I'm afraid that you've probably lost a cylinder (rings, cylinder walls or cracked piston)...

any oil consumption (or "making" oil?)

when compression is gone in a cylinder...the fuel that the injector is injecting into that cylinder can increase the oil level in the crankcase.

take care~
