that a 240 is a good possibility. it could also be a six cyl. v ersion of same engine, or a five cyl. more likely a six three liter. i would not thnk that because the ad says four cyl that that fact is correct. also five liters seems unlikely for a four cyl. not impossible though.

They put a number of different engines in these vehicles including the 220d and 240d engines. However, the non-bus versions of this particular chassis are called 508 vans (I don't know why the numbers change for the bus version) but the 8 refers to horsepower. The 220d is a 6 and the 240d is a 7 and the 300d is a 9. But I don't think they ever put the 617 in this particular style of van. The 617 is pretty rare in any of the MB vans. Many of them had a 4 cyl direct injection diesel--is it the OM 314 or OM 352 or something like that?
By the way, there's a similar one for sale on Craigslist San Francisco at the moment.

that the 617 was built originally for the 123 body cars. and it was first offered around 1974 or 5. so unless it has been changed out i dont think it would be in this bus.

It's not the same engine from a 200/220/240D. It's WAAAYYY to big in the engine bay for that. The OM352 is a 5.6L L-6 turbo/NA, that's about as close as I can find.

As both Kerry and I said, it's most likely an OM314, which is a pretty good-sized chunk of cast iron and is found in 309s and 407s. However, the 314 is 3.7L and somewhere between 70 and 85 hp depending on the year it was manufactured.

I doubt if it's a 352 because from what I can tell in the eBay pics, the oil fill on top of the valve cover is in the wrong location to be a 352.

looks like the 314 to me. a pushrod engine because of the height of the valve cover. the front water hose passing across and the oil filler look the same as the 314 cutaway.

cool pics, guys where did you get them?
