The truck is my friends, it is a 2001 SCLB 2wd auto 24v cummins. When truck is started it plumes white smoke for about a minute, it is rather thick too. After it is running for a bit the smoke goes away. Also when driving the truck and at wot it smokes more than I remember my stock 01 smoking. Any help is appreciated, to my I didn't see any codes when I cycled the key. Thanks in advance for the help. Oh and I am in Gilbert AZ and it is no where near cold here right now, 70's at night 104 in the day.

 

Turbo boot off, coolant in cylinder, bad vp.

Check codes, key on/off 3 times & watch odometer for info.

 

When mine blew white and grey smoke it was the injectors.

 

are you using coolant? if not could be the VP44 not getting the timing up to where it needs to be

 

^^^^thats what mine did about 10k before the vp exploded

 

mine is doing doing the same.... white smoke at idle and white/gray/black while driving.... I think I ran a bad batch of oil thru it and fouled the injectors...

 

If you aren't using coolant, I'd think smoked or stuck rings, or like noted above, a fuel issue.

Could theoretically be an injector hold down, or sticky injectors. Run some biodiesel through it, or some fuel system cleaner. If it's a sticky timing actuator, the solvent or bio may unstick it as well. If not, try cracking the injector lines one at a time while it's cold and see if the smoke goes away. If it does you have found your bad injector. If not, probably the VP.

If the rings are stuck the smoke should be bluish grey rather than white, but smoke levels shouldn't change much as it warms up. For this, do a solvent based motor flush through the oil- follow the instructions- no load on engine until fresh oil back in or you will DESTROY your bottom end bearings.

 

to clean your injectors try this...

go for short 20 mile drive and return home

drai the fuel filter husing and remove...

put in a new filter and fill thebowl as full as you cn get it with straight Power Service

start the truck and letrun for 10-15 seconds

shut down and land put a duble dose of Power Servie in the fuel tank

let truck st over night

if that doesn't clear it up you most likely need new injectors
