Coronado glider, 12.7 or 6nz?

6nz without a doubt, my truck with this motor has 7 years STRONG with NO OVERHAUL.

I just did the rods & mains 2 months ago just to be safe, Detroit motors could'nt even come close to these motors.

 

Cat are more expensive to repair because it's a better quality motor and last much longer than others, so you actually get your money worth along with better performance.

 

Lol Cat's quality isn't what it used to be.

 

Then how do you get 7 years without any overhauls??

 

By looking after your equipment.

 

Then i ended up purchasing a cheap freightliner truck from the auction/Cat C-15 . Driver took it OTR for 17 months and still running strong with absolutely no engine work. My other trucks with Detroit's 60 serious is a whole different story and i don't mean in a positive way either. I have 3 trucks with cat's right now and 2 trucks with Detroit's 60 and another truck with a N14 redtop. And i tell anyone out of these 3 motors, Detroit is 3rd place for me. But hey different strokes for different folk's.

 

Dude i have 6 trucks and brought and sold many others and I'm all about taking care of all of my equipment. That's how i lasted so many years doing this, Cat is a better quality motor period. Sorry i don't intend to hurt your feelings or others that's Detroit lovers, but best maintenance care on Detroit still will not change that quality.

 

True enough. My family has owned a dozen or so trucks through out the years. The Series 60 was the least problematic. Aside from needing a jake solenoid every 12-18 months it was a solid performer. The C15 seemed like it needed a turbo every 18-24 months and it snapped a few rocker arms over its life. ISX, well that should require no further explaination lol.

 

I've spent a few years turning wrenches at a Cat dealership. I'm not convinced they are a superior brand. They are just like everything else these days IMO. Maybe back when the 3406B was king I'd sing a different tune.
