871 Diesel Detroit 317hp

Hello,

I am considering looking at an RV in person (a 1964 MCIa5). It has a diesel Detroit engine. Does anyone here know anything I should ask or be concerned about with this type of engine?

In the ad they say:

"Runs and drives like a top! In frame rebuilt 871 Diesel Detroit 317hp, Tie Rods, Clutch, Compressor air conditioner."

Is this the kind of engine that needs to be rebuilt often? Would I just be better off replacing it with a new engine?

I am thinking of test driving it to be looked at by a service station but I'm not even sure who where to bring it- does a regular car shop work on these?

Thanks in advance

If it's been rebuilt properly that engine will last another 500K+ before needing anything, even if you treat it like crap.

Find a heavy-truck mechanic in the area. Call to make sure they're able to inspect it —*and be prepared to pay quite a lot for the inspection.

Ask what kind of mileage it gets. I would guess 4 mpg.

C'mon. I've seen 8v92's that get 5mpg w/automatics. Surely this thing get's 6? ;)

It will be a 8v71 and it actually producing 317hp would mean it's turboed along with supercharged. It's a two cycle engine so it requires the supercharger. It's getting harder and harder to find mechanics that know how to work on these. They can be a high maintenance engine. You should be mechanically inclined to own one. The will run forever if taken care of.

If you still proceed then ask who did the rebuild? How long ago was the rack run? What oil is being used in it? If they don't know they should be using a straight non detergent 40w oil then turn around and walk away!
Learn a lot about these engines on the internet. Bus monkey and bus conversion magazine are some great boards for buses with these engines.

Thanks for the info. This sounds like too much hassle to worry about having it serviced and the poor mileage. We are looking for something more reliable I think.

That sounds nice if you can afford the fuel to travel in it. I don't understand why you think this would be unreliable. It's had an in frame rebuild and the front end worked on.
That is kind of old though if you're looking for reliability. Things just go wrong with older rigs so you'd better be able to tinker.

Don't be afraid of a two stroke Detroit. Just educate yourself on their proper care and feeding.

I wish I could find a girlfriend like that.
