CAT C7 Engine
I have a friend who has a distribution firm and lots of trucks. Her husband passed recently and one of the 5 tons recently has a problem with #3 cylinder with no compression. Computer shows a mechanical failure likely on the bottom end. Scored liner or broken ring/piston issues are considered. The newer DT466 ( this one is 2009) is not bullet proof like it used to be. This is the second time for this engine. Unit has 10,000 hours or 403000 miles on it. All highway and has had engine work done 186000 miles ago. This truck is meticulously maintained.

I am looking at a used Frieghtliner with a C 7 CAT engine in it however I am unfamiliar with the C7. Does anyone have any solid information on these engines? After 30 years of IHC we are going to shy away from them and have heard even Penske won't purchase anymore of them due to on going issues. How is the C7 for durability and fuel mileage?

Also curious about the Cummins engines in the 5 tons if anyone knows about them.
