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.

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.

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.

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.

I really like your ads over most of the ones on YT. Keep up the shameless plugs, interesting to see what you have in stock!

You have a wonderfully positive attitude in the face of the disappointments you find in these engines.

this was a really fun one to watch with all the super torqued stuff and the sludge. Great vid Eric! I also just noticed your brooks, I think we wear the same shoes!

Great tear down video! Nothing on a diesel "just comes off". 16:25

When this engine is cared for it purrs like a kitten, barely sips fuel, and has loads of torque. Intake side and dpf do need cleaning every now and then, but it’s worth it. Love these.

Great video and very informative for those of us driving a vehicle with this Mercedes OM642 3.0L DOHC Turbodiesel V6.

That is quite a teardown! My neighbor has a Mercedes, it looks like an older car and with a gasoline engine. Your teardowns give me the impression that the Mercedes engines are truly special.

Dang, I’m getting my oil changed early first thing Monday. Yikes. Love these tear down videos. Cheers ✌️🍺

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.

love these videos. Very informative. Very simple. Just the way it should be. would love to see you tear down a 6.6 duramax!

Really interesting teardown. Very impressive how much chocolate fudge an OM642 can hold. As someone who's sliced fingers and hands on head gaskets, I feel your pain

These companies that think their engines can run for 10's of thousands of miles between oil changes are crazy!! Change your oil my friends, It's cheap insurance.

Foe every action there is an equal and opposite reaction. In this case, the engine has likely run for 200,000+ miles without an oil change, with most internal parts not badly worn. That is proof that you CAN run long intervals between oil changes. However, I do not advocate that as a modus operandi, but there's also no need to panic and change oil every 5000. There are plenty of oil studies done which prove replenishing 1/3 of your oil periodically will keep the oil in spec.

@@einfelder8262 1st of all to "replenish" 1/3rd you'd have to drain out 1/3rd, unless the car burns a LOT of oil, 2nd is yea, the additive package would get a boost but your not removing any crap suspended in the oil or what settles to the pan bottom, we have no idea if this engine went 200,000 with the same oil but in any event the crank was shot as was every bearing in the thing, severely worn and now it would have to come out for replacement or rebuild. I still change mine every 2500, why?, I'm only driving 2.5 miles to work and back, engine rarely gets to full operational temps and the GM oil life monitor also says it's worn out at that point.

@@barryaiello3127 Well, we it didn't only go 15,000 miles. How? Just a guess. In your case you should be riding a bicycle to work, instead of polluting the earth with cold engine running and in all reality wasting oil. I'm glad you pointed out that 1/3 would need to be drained, else I would have oil running out of the top of the engine. I also didn't bother to say a filter change is needed with a 1/3 oil change, figured that would be obvious. That's how automatic transmissions last forever - change 1/3 oil and filter at 20,000 miles.

People who never change their oil dont deserve a drivers license. This applies to transmission fluid aswell.

This is what a typical om642 Bluetec engine looks like when owners do the 'prescribed maintenance interval'.... but have short trips, light throttle, and live in an area with bio diesel blended oil. When I was at Mercedes, we saw loads like this, despite good service history.... and it was the first time that the parts system ever called for an engine to be a 'stockable item'. What really kills these is that they don't have an oil pressure switch, only an oil level sensor that gets stuck with that goo (which tells the driver the oil is at a good height), so the engine will get oil pressure starved and the only warning sign is when a turbo or crank fails. If there was an oil pressure warning, people would shut it down earlier and maybe could salvage the engine. Right now, I'm working on one where all the oil is black jello after 10,000km since the last oil change. The theory is that the DPF regeneration cycles get cancelled too many times due to short trips, but had starting the over fueling process, so it washes past the piston rings and never gets cleared through the PCV system. After awhile, the oil reacts (yes, even recommended Mobil1 ESP) and solidifies. Loads of opinions out there on these, amazing to terrible. When running, they are great to drive for sure. If you have one, make sure to take it on the highway for a run and change the oil at least 2x in the time frame MB says to do it. ***Really liked the video, will be a great resource for when I start stripping mine apart too!***

I loved this cos I’ve got one in my Jeep GC The swirl motors always seize up even in well looked after engines (removed mine) these engines burn dirty at best of times but this one was something to behold! I have a catch can in mine now to help keep the intakes clean.

Two sound effects would be nice: One to indicate, sell-able the other to indicate scrap/trash.

Great input

When I was a Silver Star tech for MB, I always said that these were the most abused cars because some owners thought that the car never needed maintenance. Sadly, I've seen this before but nerve this bad.

"This is easier than I thought!" The mechanic's curse. Great video! It's rare that you're this shocked at an engine.

We just rebuilt the 3.0L in a friend's R320. It didn't have any kind of sludge, and although the EGR had some crust in it, it was nowhere as bad as this. 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.

I've been waiting anxiously for this one. I have a Sprinter with this engine. Pretty sure my internals look better.

10 years is what people are getting out of their Tesla battery packs, and it only costs $18,000 to replace them. EVs need to come a lot further when we have to switch completely over

642s are HARD to kill fr. Its one of the most reliable and long lasting Mercedes Diesels its a shame they discontinued it honestly.

Hi Eric, Im Chris from Scotland, I just found your video and wanted to thank you for taking the time to invest in making the video, I have a weird oil leak at the front of my ML280 W164, but it seems to be coming from the behind the EGR intake pipe and your video on the strip down has helped. because it shows the stripping down of the front of the engine components. it is not from the oil cooler as I already dealt with that. as my serpentine belt shredded and the shreds got behind it and destroyed the Crankshaft Oil seal by getting in there. If you think it was hard betting the Crankshaft Nut off in the workshop you can imagine how hard it was getting it off with the engine in the car LOL best wishes for 2023 🙂

Don't bin those intakes! Clean them really good and resell them. They are extremely valuable. Edit 1: Those flaps in there are called the swirl flaps. They do get deleted most of the time in areas that don't have testing. Edit 2: you didn't pull the oil cooler in the valley, those are well known to seep coolant into the oil and make that Jello you're finding. You can tell if it was ever services by the color of the orings in the bottom. Orange is OEM, blue or purple are for the fixed ones.

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.

Very nice tear down. It make me thing the beautiful of the Diesel engine and how come all the parts together make a engine to run. All these parts together must to run in perfect harmony in order to get the engine run. Fantastic piece of engineering.

I love it , using my Grandpa's old tools . I will go out of my way to use 1 .

I used to work on these engines!! Awesome video! Those intake aif flaps open under load allowing more air to flow in the engine. Common issue for them to break on the m276 engine also.

Very good video, very informative. Thank you very much! I have the same engine with a 5 speed autom.-transmission in an E-Classe station wagon from 11.2007 and bought it recently used with 280.000 km on the odometer. I only bought it because it came with a good and plausible service record where all the maintenance that were done was listet. 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 :-) . I mainly use it for long trips.

The oil had been changed alright...changed back into primordial crude 😂 that was epic! I love my 7.3 more with each emissions-teardown I see.

These came in the WK jeeps as well. I love mine! Also I would have used a couple cases of brake cleaner on this thing to uncover all the fasteners hidden in sludge.

My 2001 Opel Astra 2.0 DTI only has 180.000kms (~112.000mi) and I've already had the EGR valve, intake manifold and flaps cleaned twice. Even with less carbon build up the second time compared with the first, I could immediately feel the difference. I understand that it's not an easy thing to do in all engines but even if you do it only every 40 or 50 thousand kms, it's worth it.

Mercedes uses a lot of plastic parts in areas that get very hot. Sure it is cheaper but the plastic crumbles after a short time. It gets so hot in the engine the oil will turn to vapor. I would never own another diesel. By the time I get a DPF issue fixed I could have thousands invested only to have to fix again because of poor engineering.

That must be one of those engines with “lifetime fluids”

After all that abuse and oil starvation, that crankshaft is still usable after cleaning and polishing. Mercedes diesel crankshafts are legendary, virtually indestructible

I think that this has been one of the most fascinating teardowns I have watched so far. "Pudding pickup" and "pudding pump", Yowzah!
