KKK K24 From MErcedes DOES fit D24T

[Slobodan]

I have checked glow plugs about 2 months ago, and all were working perfectly. they are only 2 years old. Bosch.
Its getting plenty of fuel. Even the ether couldn't get it going. Compression is just not there. Doesn't have enough compression to get ether to light it off.
Its ok. I am not heart broken. I do think I will be installing this OM616 I acquired. I'll probably do some cool compound turbo setup with it.

WOW, that is really low compression! How was the engine running, when it was running? What kind of air cleaner were you using? What kind of motor oil?

I bought one D24T car that immediately needed engine replacement. We figured it was because the previous owner lived at the bottom of a long steep hill. Evidently she would boot it going up that hill every morning, engine cold. Prematurely wore out the engine, compression primarily, probably not good for the turbo either.

What trans are you going to use behind the OM616?

Oil: Delvac 1300 15W40
How it ran the day before: It seem to run okay. Not 100% smooth like a nice D24T but with a little wobble to engine. still seemed to hit on all six. I am using a K&N cone filter.


On the OM616: I am going to be using the 3spd auto. Its what I got at the moment. IF I find a 5spd or figure out a Laycock OD unit for it.

The 616 seems like it may be a downgrade from the D24T in terms of power. Old tech and two fewer cylinders. The D24 platform is cutting edge design compared to the 616, it can trace a line back to the 1930s! Heavy motor for the power it makes, too. I respect them for their toughness but hard to see having much fun with it.

Won't try to talk you out of it but seems like fixing or replacing the D24T might give better results? There's always the attraction of trying something new though I suppose.

I was thinking of ways to explain your possible loss of compression. My question about the oil was because lifespan of these engines is remarkably better with full synthetic oil. I think there was a VW directive at one point to run synthetic.

The air filter question was because running a substandard filter would let more dirt into the engine, excessively wearing away the rings and cylinder walls.

Of course, we would expect these items to negatively affect the compression over time (thousands of miles), not one day to the next.

To be fair, I grabbed this engine out of the junkyard with unknown amount of miles on it. Looked clean, no leaks, Also the block was painted black, somebody was in there at some point. The car it came from looked like it was sitting for a decade. When I put the engine in to the car, I did have a hard time getting it going. but once I messed with fuel settings and putting manual glow plugs and new glow plugs in. then I had it running. .. .. pooorly. horrible miss that I dealt with for 4 years until this summer when I tried my hydrolock method to unstick some piston rings. I did manage to get the compression up on the two lowest reading cylinders, engine then ran smoothly.


I haven't done anything yet. been cold and snowy and I don't want to until I get the OM616 put back together and running.

Its still got life!!!!!
I replaced the starter, and battery, then used two sets of jumper cables.
Took a ton of cranking, and stuff, but it finally cracked off.And its colder tonight than it was last Wednesday.
