Find the biggest load you can and drive it like you stole it. Don't idle for any extended periods of time.

The first 10,000 km are critical to weather your gonna have a oil burner or a runner.
Dont baby it and avoid prolonged idling.

 

One more thing , don't change your oil early either. You can change your filter but leave the oil till your normal interval. The rings need to wear into the fresh cross hatch of those new liners. Lots of load on the engine at different rpm pushes the rings against that fresh crosshatch on cylinder walls. If you baby the engine or idle a lot eventually you glaze up those new liners and the rings never get a good seat.

This has always worked for me, on everything I've rebuilt, not just diesels but gas also.

 

Exactly, run it like you stole it. When had my 1st motor rebuilt the mechanic started it up and put it right to the floor and held it there. Still going strong today with over a million miles on it.

 

Just drive it normally, don't baby it and don't let it idle long, do regular services. Schedule an initial valve adjustment somewhere between 75-100K miles.

 

Why do you say that? I've always heard the opposite, you need to change the oil at like half interval because of the extra wear from everything breaking in

 

I've always changed the oil & filters between 1000-2000 miles of an in-frame. I haven't had a problem yet. So I too am interested in why.

 

I agree. When I bought my truck new, I ran it like I normally would, maybe a little on the hard side. Definitely didn't baby it or let it idle. I did change the oil at 5000 then again at 15000 before going to 15000 mile oil change intervals. The truck now has 375000 miles on it and uses maybe 1/4 gallon at the most between oil changes
