I am pleased to join your forum, but disappointed that the demise of my beloved '82 240 has driven me here.

I lent the car to a cute girl. (chide me for that after your expert advice). She did not check or add oil as promised and after 3 weeks she called to tell me that the car was on fire. With instruction she extinguished the fire. It was towed home and when I returned to TN I found that there had been no real fire only smoke, but I am now holding a piston and rod that go in the engine in my hand.


Rebuild is not an option.

Two known options follow (I welcome your input or enlightenment on options I can not see):

1. Replace the '82 240 D engine (226,000) with a '79 300 D engine (153,800) that I own.

[I am not sure if the engines can be interchanged but could not pass up the deal. The body is rusted through in places and transmission slips but he car starts easily and sounds great.]

2. Replace the '82 240 D engine with a '82 240 D engine (160,000) whole car minus transmission available for $700.

I am handy, can follow instructions, and my dad has an engine lift, but I have found a local shop that will pull 2 engines and replace one for 960.00. At present that is my plan.

If you swap in the larger engine, you will also need new front springs, and perhaps the radiator if it is larger.

Assuming your 240D has an automatic transmission, you'll need to check for compatibility of the transmission and differential. If you are converting from manual to auto, do some research. There are many things to consider, but it is do-able. Biggest issue is the flywheel - it is balanced to the crankshaft. If you need to move a flywheel from old to new engine, it will need to be re-balanced to the new engine and installed in the correct orientation.

It is a great idea to have the donor and recipient side-by-each when you do the swap.

Which ever engine you decide to use, eliminate all oil leaks and other short falls before you loan the car out again...

I see no problem with using either engine (616 or 617). Of course the 616 would be a direct replacement, but the 617 would go in just as easy if you had the entire donor car for the parts needed. As suggested above, you need to keep the flywheel with the engine if both cars are automatic, or get the flywheel match balanced for the engine you will use. All automatic flywheels have (or SHOULD have) a mark in the center hole that aligns with a mark on the crankshaft. Match balancing is only needed if the donor engine had a manual, and your recipient is an automatic (or vice-versa).

You are definitely able to swap your 240D engine for a 300D engine; I'm doing it right now lol. We are in a similar situation as I also just have a 300D engine but no swap car to go with it, unless you actually have the swap car.

If you had the complete 300D to use, that would be great. You'd need to use pretty much all of the parts under the car if you are going to use the 617 if you also wanted to use the 617 (300D) transmission. If you just have the motor, you can make it work I am sure.

If your 300D has automatic climate control and your 240D has manual control; you'd have to convert it. Apparently it is not that hard. I'd also recommend using the differential from the 300D if you have the whole car available to you; you'd have lower cruising speeds and might have better gas mileage. You'd also have to use the speedometer. Its not that hard to remove and hook up; to remove the gauge cluster just remove the bottom panel on the drivers side and push it from behind, it should come right out.

Seeing as you lent your 240D to a cute girl, I'd guess your 240D is an automatic.

EDIT: Since you have the engine, I would recommend heading over to the junkyard and getting a driveshaft off of a 300D. You can also get a diff if you want, but the one you have would do if you dont feel like removing it (its a PITA). Make sure the driveshaft will match up with the transmission you want to use in terms of length. This wouldnt really apply if you have the swap car at your disposal. Removing the motor is not that hard; if you have any questions I'd be glad to help you out, I removed mine about a month ago.

EDIT2: You're also going to want the transmission mount off of a 300D, but the 240D one might work, I am unsure. I'd do it just to be safe. The engine itself is somewhat simple to remove and assumedly simple to install; the hardest part is the flywheel issue etc. Just have the old one matched to the one on your new motor.

EDIT3: I wouldnt spend more on a 240D swap car if you already have a 300D engine. Its pretty much enough of a direct swap anyway and not worth spending the extra money if you already have a new motor.

EDIT4: You're also going to need a bigger radiator and oil cooler, these wont be that hard to find.

Looking for a paint color suggestion for my 240D with Palimono MB-Tex interior!

can we have some more pics of the destruction? thats impressive. That part needs to be hanging on the wall of shame!

did the connecting rod fly out the side of the block?

Blocks destroyed in that fashion make a heck of a coffee table, they tell a story-
my 1.6 for example-




my wife won't allow the above piece in our house for some inexplicable reason.





I say go for the bigger engine and do not let said cute girl borrow the car again. The conversion is straightforward, especially with both cars avialable

Dating cute women gets expensive I've always said, yet they are irresistible.

To the original topic and jokes aside:
Stick with what you have. 300D and 240D have differences. Keep what's under there. IMO $700.00 is expensive for a OM616. Keep looking. There's plenty of these cars in the boneyard at Pick-N-Pull. Grab a motor with low mileage from there. Lots of low mileage 240Ds get scrapped that are otherwise perfect because of light body damage. You could get a motor for $250.00.

That's my opinion about what to do.
Sometimes the junkyard is nice enough to let you hot wire the motor and see how it runs before you buy it. I wouldn't go in and just pick up a low mileage because what the ODO says. Then again, the junkyards do cut the battery terminals so it would make it more difficult. A lot though are lazy now so, it depends.

Good luck and keep us updated on your plans with this 240D.

Unfortunately none of the above posts are 100% accurate. The 240 flywheels are to my knowledge all neutrally balanced. The 300d flywheels may or may not be. If removing the fw from a 300 be sure to mark it and the crank so it can be put back in the same location. If you are wanting to use a different flywheel on a 300 the original flywheel must be checked for balance and if it is not neutrally balanced the new flywheel must be match balanced to it and installed in the same location as the original fw.

If converting a 240d to 300 power you need to also change over the diff and the driveshaft, the speedo and the radiator.

Good luck.

(I have converted two cars from 240 to 300 power.)

Yes, that's why I suggested he stick with what he has. A little cheaper and saves some time sourcing the parts. If you got a donor side by side no doubt I would do it though.

If your 240d is a manual, then the om617.912 is worth swapping in.

If your 240d is a automatic (likely since a girl was driving it) then put another om616 in it.

I think he does.

He says the engine runs great, but the tranny slips and the body is rusted, I took that to mean the 617 donor vehicle.

I figure if he has the thing in hand, then the swap is straightforward and it might as well happen

100% necessary comment?

I guess it just touches a bit close to home; all my wife (aka a cute girl) ever drove was stick shift and she is awesome at it. For that matter, if you wanted to start comparing shifter size, the Hurst in her Savoy is way bigger than yours

Just sayin', I know plenty of guys who can't drive stick either.

There is nothing in this world better than a cute girl who can double de clutch a manual, but girls who drive manual are becoming more and more scarce everyday.

The day I meet a cute redhead girl who can power shift a muscle car is the day that I go ring shopping...



Edit: And yes comment was necessary. Swapping a 617 in a auto 240D is the biggest waste of time imaginable.

Doubleedit: Your sword emoji is starting to aggravate me, if your going to attempt to start a flame war in someone else's thread, at least attempt to add some valuable information on the topic at hand first. I've been in his shoes with my first w123 (1981 240D) which I happened to swap a OM617.912 into (the engine he has access to), and then there's you just jumping in to light a fire. Grow up will you?

Gentlemen, please lets focus on helping the OP. I apologize for being perhaps a little rough in my first post. I nearly did not post because I was in a rush but did.

the 617 na conversion in a 240 is very nice to drive even with an auto because of the additional torque, but with a stick its really nice.

Thank you all for all your thoughts!

The potential replacement engine did come as an entire 300D.
The transmission is not working properly in that car.

Both cars are automatic and I have them side by side.

I now know that if I am going to replace with a 240D I should look for one much cheaper.

But I am still unsure what replacement with the 300D will require.




and yes more pictures of destruction forthcoming...
