Oct 26, 2014 · A buddy of mine has an '04 Freightliner M2 with a CAT C7. Approx 350k miles. He was finished for the day and was cruising home unloaded when poof, it's blowing light colored smoke and it's down on power and misfiring. He limped it back home. We started dicking around with injectors. Replaced injector on #6 cyl.

Jul 31, 2012 · The C-7 in particular the early models, I think from 2002-2004 had alot of Huei pump issues which led to injector, head & turbo failures. CAT is n ot known for honoring warrenties on the c-7. Granted I have heard more horror stories than positive ones. It always seems that way. CAT made alot of these engines.

Apr 6, 2008 · The Cat C7 is the newest version of the 3126. Not exactly sure of the year it changed, but believe it was 2004. 210 HP was all I ever ran in my 26000 GVW 24 foot Sterling. It gave me 11 miles to the gallon and did me a good job. You can look back at previous posts on the 3126. There has been several of them.

Nov 7, 2013 · You may not be reaching a needed operating temp to make the Cat sing on tune. That being said, the only time I had excessive white smoke was right before the HUEI pump failed, but it was a steady smoke bomb for about 30 miles and eventually quit two miles from the Cat dealer I was headed to.

A chemistry test will also help the test strips tell you if you need SCA. You can pick up test strips at a Detroit Allison dealership for arround ten bucks for a dozen Im sure you can get them at a Cat dealership.
