Re: c 12 cat reliabilty and longevity
I have one truck with a C12, a 1998 Pete 378 13 spd transmission. Seems to be a good engine. No problems with the motor, some with the Pete truck itself (wiring issues). It doesn't burn any oil, and its been quite a while since a rebuild. The Jakes are the best I have seen in a Cat motor. I think it is rated at 431 hp, however its not the same as my 425hp 3406 in my Kenworth. It won't lug up hills like the 3406 will. I pull a Merritt hopper trailer tandem axle with it mostly. The biggest trailer I would go with that truck is a tridem axle, I would not hook a Super B behind it, it wouldn't hold 100 km/h on the highway loaded.
