About 48,000 miles on the truck when last Tuesday I was pulling around 10,000lbs. I was coming up a hill when all of the sudden the truck started bucking and shaking in a back and forth motion. The truck dropped a gear and the motor smoothed out, but you could still tell there was no power and the engine still had a miss in it. The truck then decided to shift back into the higher gear and the same wild bucking started to happen, it was sloshing water out of my cup. I used manual mode to get the load to the jobsite, then loaded up my truck on the trailer I was pulling and got another 6.7 to tow me to the shop. They found out the #5 injector had crapped out and also some DEF temp sensor was bad.
Was there any damage done to the cylinder by me still driving with a dropped injector? The dealer says no, but I want to double check.
Usually no. Only had one bosch injector ever cause engine damage in the form of a bent rod. That was on a 2011 sprinter van with very simular injectors.
That's a pisser... I suspect it's hard to tell when a injector goes out on these trucks because of the DPF collects all the black soot you would otherwise see on a non-DPF truck.
Good to see a post from you lexus, although with a truck down.
Waiting to hear the outcome on this injector issue.
Attempting not to derail but I guess the front corner is fixed up?
