Do a Google search...there was a member on here who did this swap with success. He started selling the adapter plates. I'd give you the name of the site but I forgot it...if o come across it ill post it up. Actually YouTube "Wrangler om617" should bring up a few videos...the website is in one of them (believe its a brown wrangler w/ Mercedes emblem on the grill)
Perhaps you should check out what repacement parts cost for those engines before you swap. I put a couple hundred k miles on two different cars with those and both got mid 30's for mileage-not bad for full sized cars. After you get by the turbo lag, there is plenty of torque-but next to nothing before spooled up.
Down side: they generally do not go any farther than modern injected gas engines before needing a rebuild and you can build a really wild completely aftermarket Chevy small block for about 1/2 of what a rebuild costs on a 617. I still have one of those Benz's (82 300CD), along with a 83 380SL and both are going away ASAP-parts are just too ridiculous, even if you do all the work.
Never a gasser only diesel. A gassser engine can't use cooking oil, used motor oil, used tranny fluid, ect as fuel. Only a diesel can. I would have to disagree about the miles before a rebuild. I have seen 4 OM617's with 500,000+ miles without a rebuild. The worlds record for a street driven vehicle has a OM617 in it and has almost 2 million miles and counting without a rebuild. I don't know of any gassers doing anything like that.
I haven't priced a lot of parts for my OM617 yet just common wear items like water pump, timing components, injectors, glow plugs, ect and were very cheap. A water pump was only like $36.
My buddy has a 300d, and it runs like a top. It needs new tires though, so it's back at his home, 300 miles from school. He is driving a Honda instead, and it just doesn't have the character and quality like the Benz!
I'd agree, the om617 is akin to the jeep 4.0. Most just need minor maintenance.
Hi guys, im getting everything together to pull off this swap. Found a low miles 82' 300TD that has little blow by and no leaks of anykind. YJ's 4.2L is getting tired, and it has a AX15. Seems like a pair of motor mounts and a bell housing adapter, fuel line swap, and some other trivial block grinding, oil pan hacking will be needed. All in all I was a fan of a 4BT, until I realized I could pull this swap without a stack popping out of my hood; and a more importantly, pull it off for the price i had set aside for a 4BT, while keeping my stock drivetrain. I think the 617 is a wonderful alternative to the 4BT, if sub par performance is acceptable to you, assuming you can get a donor car for next to nothing. I hope to be ordering a bell housing adapter from Koch Enterprises (who has already been incredibly helpful and informative over the phone about what to look for when buying a 300D) along with motor mounts within the week. If anybody has tips suggestions or what-not let me know! Ive been reading JEEPFourm.com for some time now, but only today became a member. Lots of great info here, and everyone seems friendly and very helpful to each other. First thing on my list though is to upgrade from the free membership ASAP, im realizing all too quick 200x200 pixels isnt gonna cut it.
