Dt466 life expectancy

500k is upper for these, but so is 16-17 years of service too. All you can do is run it and see.

 

What matters is how much they asking for it.

 

I just had 850 000km on mine with 22500hrs. Just heui stuff along the way

 

I'm looking at an 02 bus with a dt466e that was just rebuilt. It had 258,000 miles on it. If it is rebuilt does that restart the clock on the engine? Is it like new? I know all the other components will have aged, but what is the expected life of a rebuild?

 

I'll tell you a little story... Years ago we rebuilt a 466 for customer. He wanted a works kits installed, reman head and that's it, nothing else extra. About a week later he came back saying it had no power and he was really mad at us. Of course we looked at right away and we found the air to air hose had split open to cause no boost and therefore no power. All this guy kept saying, "This engine was just rebuilt, this engine was just rebuilt..." The air to air hose was not replaced at time of rebuild and it was fine when reassembled. He had a hard time understanding this hose was the point where the new parts ended and the old parts started and thought because he had a "rebuilt engine" that every single part under the hood was new and would never fail. So this is the big problem with "rebuilt engines". You can rebuild an engine a 1000 different ways. Some can include new turbo, new injectors, new pumps and so on. Others can only slap in new pistons and call it "rebuilt". In general, there are several seals and gaskets that never get touched during most rebuilds, such as front cover and rear structure stuff. Sensors and wiring harnesses are not touched either. Cam shafts and followers are generally not replaced. So it depends on what they replaced, and who did the work and what sort of warranty is available for that.
