DieselAddict,

Read the thread you referred me to and although I've heard of Redline I don't know where to buy it. Any ideas? My mechanic suggested that I use Pro-Gard by Chevron with Techron and said it would clean my injectors. But I think using these additives might be a mute point since I used them on my old injectors to no effect and I just had new injectors installed last week and the problem didn't go away.

Several people to include Jim Smith have suggested that my prechambers could be clogged with soot. I received another email today suggesting the same problem. He wrote:

"If you are not consuming engine oil - then you are not burning engine
oil! When a diesel starts cold - there will be a blue/white smoke
whenever the prechambers are NOT hot enough. If you allow the plugs to
glow for an additional 15-20 seconds AFTER the dash light extinguishes
and THEN start the engine and the smoke is reduced - THEN YOU HAVE JUST
SHOWN THAT WHEN THE PRECHAMBER IS A LITTLE HOTTER - THE SMOKE IS REDUCED
OR ELIMINATED! The glow plugs reach maximum temperature (about 1080 deg
C) after a total of about 30 seconds of glowing!"

I did exactly what he suggested and the engine started so quickly, that it startled me. Don't recall it ever starting that fast except when I first bought it. Additionally, there was absolutely no smoke, gray, white, or blue; again, the first time in two years the exhaust has been colorless, and although the engine was missing, it wasn't nearly as bad as it has been.

So, it appears he and Jim hit the bulls-eye on this problem. Now my question is that since high speed road trips haven't removed which is likely accumulated carbon/soot in the prechambers, would you suggest that I have the mechanic inspect the prechambers and if they're clogged, to them cleaned or is replacement the normal procedure?

Thanks,

Skip
