I retract my former statement. White smoke means one of two things; 1) is coolant in the combustion chamber, this usually means the head gaskets are torn, but could mean a cracked head. Neither of these is common. 2) is air in the fuel system. Since air compresses and diesel doesnt when it enters the combustion chamber there is WAY more air then fuel, this creates a 'hot burn' situation. Check the fuel filter housing for leaks, then check all the fuel lines.

definitly not a headgasket problem.. the coolant hasent even dropped or bubbled over.. could be air in the fuel system.. didnt think about that but its running rich so i dont think it would be that..

Why do you say its running rich?

if you walk into the smoke it smells like raw diesel really bad..

Rich burning would be black smoke. White is incomplete combustion, that makes me think even more that its air in the lines.

how woul i troublshoot that.. fuel pressure tester, leak down test. etc... the test i would do to a gas motor?

You can test the fuel pressure between the lift pump and the injection pump, but the pressure between the IP and the injectors would be very high and dangerous to test. After checking for fuel system leaks, check that the lift pump is working. If thats fine then your pickup tube inside the tank is the next most likely cause.

will water i the tank or anythig like that cause it to smoke? perhaps some bad diesel if thats possible. the crap that is in it is from deleware and its only 1/8th of a tank.. god only knows how long its been sitting..

water will make white smoke. Id fill it up and see if it makes any difference.

Water will make white smoke, but it would have to be A LOT of water, and your truck has a water seperator in the fuel filter, and when that fills up with water, the SES or WIF light will come on.

Wait? you only have 1/8 of a tank and it is smoking? Fill the truck up. If the problem goes away then the pickup tube has a hole in it, and thats how air is going into the system.

we shall see.. if i get done work at a decent time today ill fill it up and see what happens..

So.......

i worked till 7 pm every day this week and i just woke up today.. im gonna see whats going on with it today then let you know.. i got a diesel freind coming over to look at it tomorrow reguardless..

Any news?

not really its sitting at my shop.. i been messin with the jimmy so i havent got back around to it yet..

Alright, well keep us updated.

Where you at 007Jimmy ??? I read this whole darn thread and now its been over 10days and you still haven't had time to fill up the tank??? And report back??? I am not buying that bullshit !!! I'd expect this from a Newbie but not a Mod. Sorry for the butt chewin, but its true.

it's joe, it'll take him a while lol
