Mercedes AMG engine nightmare

When I was in my early 20’s, I was running an excavator building wood roads pretty far back in the bush and we lost an injection pump on the machine…an old school Cat mechanic came out to see what went wrong and he figured it was from fuel contamination…we fixed that problem and I figured he would take the injection pump off and take it back to the shop and swap it with a new one but he decided to rebuild it sitting on the machine!…I asked him “is that wise”… he said he did it all the time so here we were in the bush with mud and grease all around us, building this pump on a Saturday morning and it was quite intimidating to me and I asked him how he could handle the stress of pulling such intricate stuff apart like this in less than ideal conditions and he stopped what he was doing and looked me in the eyes and said “people are way more complicated than this pump and at the end of the day it’s just nuts and bolts so don’t stress over it”…nuts and bolts indeed!!

The young buck honouring all the work Dad's done and proving he's worthy of respecting the legacy long into the future. Gets me a little emotional tbh. I can see why he's the apple of your eye Dave, I bet you ran a tight ship at home, just as you do at the shop there. But as my grandpa used to always tell me "the quality of a man's children say a lot about the quality of the man." And my father was one hell of a quality man. I sure do miss my Dad, I hope to be half the man he was. But just take a look at Hunter Biden vs Don jr. and the young Barron Trump for an example 😉 Had to chuck that in, just poking fun folks. I'm an Aussie and don't care about that. At all. Jokes aside, although I don't have any sons, only my daughter, (who's a very impressive young lady), I do have a lot to do with young lads in my community through my volunteer work and there's a sorely lacking culture of respect going both ways and just a little bit of encouragement can take a young man a long, long way. Worth thinking about folks. Worth thinking about.

[@Laurelinad]

exactly. if i was 18 again i'd move over there from germany to learn as much as i possibly could

[@richardfehr1838]

I've seen this failure before. It isn't a forging defect, it's an INGOT defect. When the ingot cools, the top end of the ingot shrinks and there is a giant divot that forms. When the ingot is reduced in size by hammering it is customary to first cut part of the ingot off where the divot is. Any remaining part of the divot is hammered shut by the initial forging but sometimes the two sides don't weld themselves back together and you get what I believe are called "cold shuts". As the ingot is reduced in size more and more until it is turned into a billet, the cold shut will be there waiting right in the middle of the billet. It is pretty rare, but it can happen. I saw this happen on a giant steel flex disk produced by Leningrad Metal Works. It caused some panic as it was on a 50+ year old machine and we had to figure out it this was going to happen to all the other flex disks (24) or if it was a singularity.

[@louisvanrijn3964]

OK, if I understand well; and when the cranck is scrapped, I could saw it through. Polish the ends in the lab. See how deep the cracks are...probably 1 - 2 mm ? If it is a manufacturing defect MB should provide a new cranckshaft.

[@jackking5567]

@@louisvanrijn3964 You're not understanding op. The crank metal was effectively folded over a sunken part of the billet. That hole is within the metal still as the opposing sides never forge welded themselves together.

[@richardfehr1838]

@@jackking5567 We have different ideas on how it occurred, but I think we agree that the flaw was in the piece of metal the crank was forged from. I have difficulty blaming MB for this failure, if the crack was present but hadn't reached the surface yet, it would have passed Magnaflux.

Not a flat plane crank, still a traditional cross plane design. The only Mercedes V8 I know of with a flat plane started in the newer AMG GT R Black Series.

[@ExtremeToTheBravest]

Yup, from what I can see, the crank has rod journals that are 90 degrees separated from each other, not 180. Certainly not a SBC 350, still not a flat plane crank. Good video still.

[@hw4075]

exactly what I was going to say, this is a M156

[@petebach7221]

Good catch.

[@Toadster250]

I was thinking the same thing but it looks like two rods go onto the same rod journal. Most V8 they are all offset to their own degree to get the firing order timed evenly between all 8 cylinders. This is probably easier to make like this and stronger than traditional V8. I was thinking a flat plane crank in a v8 would look like a 4 cylinder crankshaft basically making your v8 like two 4 cylinders tied together.

I can only imagine what the customer is going through trying to get what he’s already paid for and getting the song and dance routine from the dealer and the repair shop that the dealer trusted with the initial repair. Short of going to a tech school and getting a degree in automotive engineering and then apprenticing with a master mechanic and then doing the work yourself, the customer is caught between the dealer, who doesn’t possess the knowledge or skilled mechanics to service their more complex or older models, and the repair shop that was struck with the problem. I have a 24 year old BMW E39 M5 that I can’t trust the dealer to fix correctly and the independents refuse to even look at because they don’t have mechanics with experience on the vehicle, so I do all the work myself. It’s an education in human nature and automotive mechanics at the same time. Great video and can’t wait to see the final outcome for this engine and for the owner of the vehicle.

It will cost you now or cost you later so might as well spend to have it done right and save the headaches.

its really not that bad at all if you do it right the first time.....and do it yourself to save money. The engine is very reliable. Almost 200k miles on mine daily driven for 5 years straight@@GroovesAndLands

The amount of detail is technical information here is so amazing! I'm sold by you guys. If only the mechanics here in Singapore were half as good as you guys... I go to them with problems on my car, and most of the time they just don't wanna touch it! :(

[@MaGdAn7]

2 decent mechanics to watch at long last. Thank God still some good mechanics out there. You have done an excellent job with your son as well. Keep posting guys. Best I have seen on utube.

[@justinhartsell4418]

Hes 100% wrong about that being a flat plane crank that is a cross plane crank. On a flat plane crank the rod journals are 180 degrees out cross plane is 90 degrees. That is definitely a standard cross plane

[@quicksilver462]

I also noticed that, now how can I trust this guy to build my AMG motor if he can't tell the simple difference between cranks!?

The famous AMG 6.3L V8 was never a flat plane, neither are most of their engines, with exception of the recent GT Black Series.

​@@brucedale4465😂 and how would you know goober? Is it because you're watching one get repaired on an automotive repair channel?

[@GXMAN16]

@brucedale4465 How so? One of the best and most reliable AMG engines made, there are people with up to 200k miles in theirs. The crack in this one is some kind of freak accident. But look at the size of that crank and it's the same size as the cranks from heavy duty desiels sitting in Dave's shop. I bet you that thing would have ran with the crack in it .

[@zf4hp24]

@@brucedale4465 I own a 100K mile M156. Original head bolts, original cams, phasers, and lifters. No wear, no leaks, no problems. Did have to replace the crankcase breather. Overbuilt, hand assembled, and massively understressed.

Guys, this was a SERIOUSLY well produced video. This was very entertaining to watch, and kept my interest. Better than anything I've seen on pro-TV production (Discovery, etc). Whoever edited this did a great job keeping it entertaining and tight. Subscribed.

[@samte4672]

so Mercedes cant fix their own stuff but dave can 😂🤣it says a lot !! great video as always 👍

dealers outsource engine and trans usually. Or just install new motors and trans.

[@partymanau]

Had an air con compressor problem. Traced it to the control solenoid, a common fail on that particular variable stroke compressor. Asked the Benz dealer to change the solenoid. He said no, they would swap out the whole compressor. He said they weren't trained to do the solenoid. (1 electrical plug, 1 circlup then a regas). Stay away from the dealer shops, go to the privateers.

Mercedes is a manufacturer. They make money selling what they make. They leave the deep dive repairs to the people that will eventually buy the stuff they make.
