Mercedes OM642 3.0L TurboDiesel V6 Teardown. This is Exactly How NOT To Treat Your Car!

If this is the first teardown you are finding, there are over 20 others I've done! Lots of LS's, A viper engine, rx8 rotary, and a couple SRT8 Hemi's to name a few. Check them out here • Blown Up Engine Tear D...
My name is Eric and I own and run a full service auto salvage business called Importapart located in the Saint Louis MO area. Part of our model is dismantling and selling parts from rare and niche market engines. If you're interested in buying parts from other engines I've torn down, email us at Importapartsales@gmail.com.
In this video, I tear down a Mercedes OM642 3.0L DOHC Turbodiesel V6. This engine comes in a ton of Mercedes models starting in the mid 2000's and even Sprinter vans, Jeep Grand Cherokee, and the Chrysler 300 in different parts of the world. This was the very first OM642 I've torn down and let me tell you, this engine tested my patience. Between not being able to use air and the condition of this particular engine, I didn't have as much fun as I normally do. I'll remember this teardown for ever. Now I just need to figure out how to clean all of this up.
As always, I appreciate all the comments, suggestions and event criticism on my videos. Thanks for watching and I'll catch you on the next one!

@Scott Duffy That is a bullshit argument. Since when are you forced to go to a dealer for an oil change? Places like Jiffy Lube have the proper filters and oil to do simple services like oil changes on most brands sold in this country. I am a retired Euro- junk tech and can't tell how many times I heard shit like "I am too busy, or my car can go "X" miles on an oil service" or my favorite , " My Grandfather never changed his oil and his car lasted bullshit number of miles" Stupidity must be bliss now and that is why we have so many happy dumb asses around. OK with me I made a shitload of money off these clowns.

i have this same engine on my 2014 ML350 with 100K with zero issues. Love the torque and smoothness. The best car engine I have ever experienced. I change oil every 5K and use engine flush on every oil change. Every 25K miles I use two or three cheap engine oil changes to stop the oil change color (to black) as soon as you pore it in. Expensive Liqui Moly low ash oil is an absolute must for these engines. Every 50K miles - change fuel filter, engine air filer, PVC valve, few critical O rings and you are golden. Clearly this engine is not for 15K oil change type of folks. If you love to take care of your car, this engine will last forever. 500K in Sprinters is very common.

Hey I just did all the filters (L&R engine air, cabin air, fuel, oil), turbo inlet gasket, and a deep clean of the engine bay. I didn't do the PCV. I used Mobil 1 ESP since it meets 229.52 and might do another change after 5k (I think the interval was 7.5k or 10k previously) to get everything cleaned up in there.

The flaps on the intake runners are similar to a variable length intake manifold design. By opening and closing the flaps, they adjust the swirl going into the intake ports, one position is better for high power, one is better for low end torque. It can also be used to control the pathway/flow for EGR depending on the engine.

@t-yoonit 2 жыл бұрын

The swirl motors are very common for failing on these as well. At least in. The WK Jeep variant, the CCV system separator inevitably becomes ineffective allowing raw oil into the intake tube at the turbo where it leaks into the turbo valley and soaks the swirl motor causing it's eventual failure.

@em4703 Жыл бұрын

@@t-yoonit Change the orange seal on the turbo yearly, that's the secret from my experience. Also, change the PCV valve and it's camshaft connector seal every 40-50k km and the issue with the flaps getting stuck is eliminated. No oil in the intake = less sticky stuff for the EGR soot to cling onto (and also less oil dripping on the flaps motor).

The flaps induce turbulent flow. Since diesels use direct injection, the air needs to be turbulent so it "spins" inside the cylinder as it compresses. This is supposed to promote fuel mixing for a cleaner burn. That's also the point of the cups in the pistons.

The #3 main spun ever so lightly, but the engine was as seized as the one you were messing with. Matter-of-fact, the part number on the bearing was still very much legible. Of all the engines we've rebuilt, this one is the first one we had to take a torch, hammer and chisel to get the bearing off the crank to have it ground. Rumor has it that the #3 main spinning and seizing is quite common, according to the shop that align-honed the block.

But even when I was rebuilding the motor it wasn’t this sludgey it was really clean and the rod bearing were all mint same with the cam bearings. It just shows if you take care of a Mercedes diesel they are really good motors. Hoping to get the head back soon and get the motor back in.

Thanks for the video. You did a great job of not stopping and completing the teardown. I have a MB with this engine so it was very interesting to watch. I am thinking the owner was using a stop oil leak additive for a long time and not changing the oil. The main area of leaking I think is the oil filter housing o rings getting brittle and hard causing a bad oil leak which will destroy the accessory drive belt in a short time. I agree that the emission control on this diesel engine causes a lot of problems. There are so many problem areas with this engine just to keep it from throwing out black smoke. You are right also in that most of these parts are not cheap. I can't wait to get rid of this car but I have so much money invested it's hard to give it away. I would bet this engine was one of the hardest you have done because of the oil sludge. Thank you again.

The benz diesels all had this issue, especially the heavier duty MLs. I was SO CLOSE to buying one with a bad engine until I talked to a rebuilder. He clued me in to the fact that these motors are designed to run so hot (note the oil pan diaper) that they cook the oil. They had something like 11 oil spec changes in the first few years of operation (while most motors were still in warranty). The turbo and the design just cook the light ends out of the oil leaving that thick black sludge behind. I'm willing to bet serious money that this motor had pretty regular oil changes (probably at a dealer). This type of failure was seen in vehicles as early as 80k miles.

@@hybridorbital85 thing is they don't run that hot, they have 76°C thermostat and EGR cooled combustion for NOx suppression. More likely culprit would be extending already insane 20k miles long life oil change intervals, commercial vehicle owners are known for this because they want to save money and minimise downtime or using cheaper underspec oil.

Right after I bought it, I gave it a new oil change both for the engine and transmission and all the filters. It runs great and I hope it will last another 300 k km :-) .

As a mercedes mechanic i can say that the OM 642 is pretty indestructible when good maintained. Actually any mercedes engines are good besides the Renault ones and the OM 656 Straight six and OM 654 straigt four engines. Edit while watching: Do not lay down those diesel injectors. They Absolutely MUST be stored in a standing position. If not it will be pretty impossible to bleed the air out. If you plan to reuse them.

@Mike Studmuffin if they used the correct oil -- this engine shown clearly used regular motor oil or diesel oil and not correct the euro spec low ash (only a few companies supply the correct oil in N america and some dealers get it wrong also and all oil change places ive seen) (the merc specs changed depending on year also) .. in the sprinter the engine is detuned to 180hp apx, if its pre DEF that is even better maintenance wise as the DEF system is very costly to repair. We have 4 sprinters with the 3.0l turbo diesel like this one. All 4x4 models. Th engine is good for 300-500k miles easily usually and often more but depends on maintenance.

Nice work, I enjoy your tear down videos and your well informed commentary. I have come to the conclusion that modern engines start as a good idea, but then, because of emission regulations and trying to squeeze out every last bit of power, the good idea turns to crap and they become over complicated, unreliable and basically unserviceable piles of crap. The would end up costing more to repair than to replace or scrap, which is sort of anti-environmentally friendly.
