White smoke at idle. What could it be?

[Blacksdieselhp]

I finally got my truck to run like I want. After installing the tst/ez stack and the SP66, I was very disappointed. Then went in a set of 100hp DDP injectors. Helped a little. So I made myself plug to go into the relief valve on my lathe and man this thing runs now. I'm finally happy with it, for now anyway. But I have been noticing white smoke at idle. It don't do it all the time. I first noticed it at the gas station when I went in to pay. Then last night I noticed it again. Not sure if it done it before i capped the valve or after. Any ideas?

What does it smell like? If it smells like a sulfur smell its probably Coolant. Or it could smell like burning oil and in that case you're burning oil. Those are the only two things that I can think of that would cause white smoke. Black or dark smoke is just unburned fuel (hydrocarbons). This is typical when chipping a truck because alot of chips increase fuel pressure or duration increasing fuel delivery and causing incomplete burn. Make sure its white smoke and not black smoke.

A haze of white smoke is common with heavily fueled trucks. I see you have big injectors so that's probably the cause of it. I doubt you have anything to worry about.

Yea, it smokes kinda like an old 12 valve with the timing advanced on it. its not oil or coolant. Just wandering if plugging that valve might have caused the computer to change the timing.
