At start up and sometimes in gear at idle, it's pronounced enough now that I can see the color. Somewhere beetween gray and white. I read once what colors were what, but I can't remember. Anyone know?

sounds like an injector. have someone check your balance rates to be sure.

That's what I figured, thanks! So this is 50,000 miles on this set.

Seeing that you are not talking agout orig. injectors have you chked to make sure you are not using coolant. How long has this been going on?

Smoking for about 3 months. Seems to be getting worse. I don't seem to be losing any coolant.
