My chevrolet 6.0 gassers just keep on tickin. General maintanance thats it. I havent even had a tranny rebuilt in one of them in 300,000 miles logged between them.
I have a 97 powerstroke diesel with 138K miles on it and that hunk of garbage plays ring around the rosie with all the mechanics around here. It keeps them all fed. someone said it above, they circled the problem.... I know there not all this way, but I wont own another one I can tell ya that.
