I have a 95 ctd with #5 plate hx40 and
4" exhaust with single stack. The problem I am having is in the mornings the truck starts and if i let it warm up it will miss and white smoke in for a bit. Then i was driving it the other day and going doun the road bout 60 then let off the pedal a bit to almost a coast but not quite, it white smokes a good bit. But if I let off the pedal all the way it stops or if I give it more pedal it stops. The truck also white smokes if i have it in neutral and raise the rpms up fast to bout 21-2500 it black smokes for a split second then white again and it sounds like its missing. Whats the problem causer? Fuel lines, timing, what the heck is it? Fuel pressure is always good.
Thanks Tim:CRY:

I'd agree sounds like either air in the lines or timing. I personally would check timing first, its more expensive but you can verify it quickly as appossed to chasing an air leak for a long time. You could even bump the timing a little

You might be able to pressurize the system with 10psi of shop air to the filler neck and check for leaks with bubbles

yea mine seemed to stop smoking pretty much for good when i bumped the timing up. but it seems like air in the lines too
