Low Power 1986 DT466C 400k miles

Yeah I've heard these engines are bullet proof!! So in your opinion you'd say run it on the road? I'm looking at some loads 800-1200 miles one way.

 

Oh and I forgot to ask. Roughly how much would you say this rollback flatbed weighs empty? It's the one pictured in my profile pic.

 

Yeah I'll have to send one off and see what's really going on. I can't help but to feel like something is off. I can't see dropping speed so fast with all the momentum I have going and holding out wot on such small hills.

 

Maybe the algae is still working its way out or the injectors are weak are my two thoughts. I've checked the exhaust manifold temps and a few of them run at hottest 175ish. The others are 210-230

 

that's what I can't understand, this thing is turbo'd too. I don't even really hear the turbo until 2000 rpms, maybe 2100. I can hear it good and it sounds like it's working great at high rpms. I just can't get over that between the 700rpm idle to around 1700/1900 rpms there is almost no power whatsoever.

 

I have a mechanical fuel shut off, how can I tell that this is in the "full run" position under the hood?
