MBN Problems....

I am getting a inframe on a cat c 15 2001 Kw serial 6nz35729 732,065 miles. Is there a aftermarket injector option available? The head is cracked in 4 places, so I need a new head too? I want to fix my baby up nicely while I have the chance.

 

a 6nz cracked a head? i only thought the 2ws did that

 

Brian can do that in 5 minutes, i think they go by rev's per mile. 476 for 11R24.5

 

And a C16 with the pyro running at 1400*F....

 

They all (C15, C16) crack between the inlet valves, its very common, if the cracks aren't too bad you can re run the head with no problems, I have seen it done many times.
Heat does make the problem worse and happen faster, I have seen cracks wide enough to put a pen tip in.
Have also seen cracks between the valves on 5 out of 6 cylinders in a engine that was being disassembled for other reasons. It had no faults that would indicate the head might be cracked.

 

we had a 3406e in my truck , the oil cooler went sending temps to the roof , after changing it water started going in the oil and it jammed the engine when we lifted the head in was cracked in 2 cyls, we just dropped in a 6nz, never knew they cracked also

 

My 02 6NZ 550hp was a freak too.553hp # the flywheel,524 @the wheels.I wish I would have kept it

 

Not to disagree, but are you sure about those numbers? From what I have seen there is usually a 10-15% difference in the flywheel rating and # the wheel numbers. Sometimes the difference is even bigger depending on the type of tranny, rear end gears, oil in the boxes, and even type of tire.

 

Yep.Had it dyno'd in Fargo # Butler CAT.I sold the truck to a friend, if he didn't throw the dyno sheets away I can scan and post em here

 

Dam.Thats twice I've hit the wrong symbal for the at sign and didn't catch it in the preview.Must have another cup of coffee.lol
