Last Friday my truck did something I have never seen her do before. After the truck had been sitting for a couple hours, I went to start it and had a good amount of white smoke billow out of the exhaust while in park. After a watching if for a day, here is how the smoke plays out:

1. Start up = White smoke
2. Idol in park = fairly clear
3. Idol in drive = occasionally random puffs of noticeable white smoke.
4. Acceleration = Mix white and black smoke
5. Revving the engine in park = Mix of smoke, almost looks brown

You can see what I have in my sig…any suggestions?

Thanks in advance for the insight.

 

Could I have an injector leaking?

 

Mine is doing the same thing But When idle it is shakes when cold ,Had it to the dealer, they say nothing wrong ! If computer says it good ,Then they can not fix it . I Have about 14k on her ! Already Lost # 4 Piston And a Head ! This Is My 5th Dodge Cummins And I Hate to say my Last !

Regards,
T-B

 

Wow... What caused the #4 piston to fail?

 

pull off your intake tube and see if your turbo shaft has any movement in and out a little up and down is ok but in and out mings a worn out bearing and the white smoke could be oil from that bearing.
