Things I Learned [Vacuum Lines, Wires & Timing] - W140 OM603.97x "Rod Bender" Engine Swap 

glad it helped. the w124 are much more straight forward to work on IMO. best of luck

Glad it helped!

Magyar last name? Egan!

cheers! good luck

Great idea, car is in hibernation for the winter. Furthermore the exhaust is an aftermarket and I am not a fan of the noise it makes, currently looking for a resonator or an OEM exhaust

As far as I know, the W140 does also use vacuum for the transmission. There is a little green nipple that goes to the transmission, along with adjuster knobs for the "force" of each shift. This can be found under the shifter boot in the center console

Glad it was helpful!

Wish I could, the W140 does not have the typical 'flying saucer' vacuum line distributor as other Mercs from this era, could you please specify the model you are working on?

meaning the bolts at the front? yes. they are the ones that hold you IP pump in place

Not familiar with the OM606, it's a little newer model, but I can tell you that if you can find a OM603.960 it's a bulletproof engine known around the world to run for 1 million Km's. They still use them as taxis in the Middle East and Eastern Europe!

Im a year late to your comment but I have the same car. Fuel leakage sounds like the copper crush washers in the injection manifold. And your car not shutting off is vacuum, I had the same issue and I had just knocked off a small little vacuum fitting, it took me 4 hours to find but if you shut off the car and listen you can maybe hear a hissing noise.

Nooo, luckily this engine never made it to that stage, but the oil burning, noise and lack of compression were clearly pointing to the fact that these cylinders were over bored. Originally the car was sold as a 3.0L with 3.0L pistons, but the block was from the '87 model, being 3.5L.

Sorry, the other way around 3.5 > 3.0

Hey Dustin, car is in hibernation at the moment. Send me a private message and we can chat about it.

@@bencesmercedesgarage7479 not exactly sure how to private message through youtube!

No, I mean't the gauge wasn't reading properly until I switched the wires

Hello, I have not forgotten. Tomorrow I will get under the hood and take a look for you :) Bear with me for one more day.

140 500 06 55 is the shroud

Bence's Mercedes Garage thanks

Bence's Mercedes Garage I order in Mercedes dealer and is not the one . Don’t know can you check the numbers. Thanks

Luis Vazquez I wish i could send you the picture. But this is the same number from my fan shroud cover. Which model car do you have? If you have the W124, it is likely smaller than the one for the W140.

Perhaps its a starter....check the serpentine belt, hopefully that's the easiest fix. If you hit the starter with a wrench does it turnover? One last thing that I could think of would be air in your diesel system somewhere.

Bence's Mercedes Garage I haven’t actually hit it with a hammer yet because it tries to spin but is really labored like not even a quarter of a crank turn. I was thinking about pulling my injectors and hoping coolant doesn’t come out. I’m gonna swap a 17 head on and put a 606 head gasket. I just hope it’s not a hydro locked cylinder

​@@nicjohn6375 I would recommend first, Checking if you have good pressure coming from you Injection Pump. You can do this by individually unscrewing the lines coming from the IP pump to each injector [14mm wrench], you should see a pretty violent spray when turning over. Start at the furthest cylinder from the IP pump (#6) and work your way back. This will rule out the air in the system as well and effectively bleed your system. If you had a blown cylinder head gasket you would know if you were burning coolant, trust me. I've had one before. White smoke and smell. If your engine isn't even turning over...I would probably assume the starter as well. I don't know what this has to do with your new battery...Is it a OEM Mercedes Battery? Our other W210 (2.5L Diesel OM605) occasionally suffers from no turn over, specially in very high and low temperatures we've noticed. Likely the starter, but hitting seems to do the trick for the time being.

Bence's Mercedes Garage I’ll try tapping on the starter cuz I’m running a 220GPH lift pump and a smaller back up so 2 lift pumps 1/2” line to the IP w/35psi of FP. but it’s the first fire after 3 years and started right up ran pretty good then developed a knock stalled then when you try to fire it again it just won’t even make a full revolution. I don’t think air in the line would do that. The 14 head also used to blow oil out of the turbo so I’m hoping it didn’t pump all the oil out and lunch the engine on me

@@nicjohn6375 Ah I see, so it's modified. What do you mean by "14 head"?
