I called the local chevrolet dealer the other day , and ordered a few items , then joked that I couldn't believe they only lasted 350,000 mi. then there was silence. He replied "seriously"
I know someone has more than than that , lets see who.
How many miles do you have?

 

160,314 atm.

 

298 on my truck 435 on parts truck, both run, and the parts truck has never had the engine rebuilt

 

300 on my 95 and somewhere way over that on th 94 but the odometer quit working right so I really don't know.

 

I have 168000 on my 1995 6.5TD. So far just had to replace the ECM. and a few other issues but still a stron motor
