replaced fuel pump @ 46000 miles and now @ 166000 miles pump is out again rear main seal leaking radiator leaking for second timel

I paid a 5,000 dollar premium for a diesel engine and the thing is constantly having problems

Diesel engines commonly run one million miles without problems but this one can barely make 100 thousand miles without a major failure.

when I bought the truck no one told me that there would be a 1600 charge to remove the cab to do any work on the engine,crazzy!!!!!!!!!!!!
