Great job as usual! I was a tech for 37 years and now teach Auto Tech at the same community college I attended from 1980-1982. I teach engine repair and your adventure of flying parts is just another day during a lab. Valve keepers are the number one UFOs in the shop. The crank has to turn 2:1 to the cam. The reduction at the idler allows some of the reduction to be done there and the cam sprocket to be smaller. I worked at a VW dealer from 94-97. The VR-6 engine used the same tech. I read about it in a VW intro manual and VW bragged about how they were able to reduce the width of the cylinder head by 100mm (about 4 inches) so they could put the engine in smaller cars. GM also used this on the 3.4L. Chain from the crank to the idler and belt from there to the cam sprokets The location of the timing components is being driven by the insurance industry in Europe. In the US we have the IIHS that issues safety ratings. In Europe, they have Euro NCAP. Euro NCAP figures in pedestrian injuries as part of their ratings. The ratings are used by insurance industry to set insurance rates for vehicles. When a pedestrian is hit by a car, they often end up on the hood of the car. If there is space between the hood and engine and hood does not hit the engine as it is being crushed, the pedestrian suffers less injury. By putting the timing components in the back of the engine (with the corresponding "hump") there can be more space between the engine and hood. MB does this on their hoods. We get the hood hinges to do it here in the US, but not the pyrotechnic actuators the Euro cars have. We will soon have this tech in the US. Buried deep in the recently passed Infrastructure Bill is language that directs DOT to start the process of setting standards similar to Euro NCAP. There is a lot more of this stuff in the Bill as well MB came out with a 4 cylinder diesel in the 2010-2020 time frame with the chains on the back. I worked at a MB dealer from 2013-2016 and we had to have a $3500.00 engine stand because of that motor. The engine attached to a frame where the motor mounts were that connected to the engine stand. The crankshaft was 90 degrees to the axis of the stand. The engine was rotated by a geared hand that move it end over end to get to bottom and top of the engine for repairs.

Due to the way that the way the German workforce is structured, I wouldn’t be surprised if this isn’t just isolated to the industry I work in.

A lot if not most of the gasket issues in BMW’s were realized after BMW changed to an O/C interval of 15k. They have since revised that down to 10k, but enthusiasts who take care of their vehicles change the oil every 5k-7.5k. These engines will last a LONG time if you take care of them.

Absolutely 100% agreed. Only morons will adhere to the extended change intervals of oil and coolant. Does anyone remember GM NorthStar engines? Intervals set at 100000 miles? used in some Cads and Olds, maybe others. They turned out to be a disaster when not getting their Oil and Coolant changed. That engine supposedly could run for a long time without coolant even. VERY BAD IDEA. Do yourselves a favor, and let me give my two cents worth of knowledge (having worked in the oil and gas industry for quite a while) Oil, wether synthetic or mineral, all come out of a hole in the ground. The difference on the synthetic oil is additives and monodispersed balls (also known as the Uglestad balls after the nowegian inventors name "Uglestad") They are really microscopic uniform polymer particles, perfectly spherical, and acts like ball bearings. (invented for use in medical research at first, but other industries like oil caught on) They were a revolution when released on the market, and Mobil1 containes these to this date. This is why Synthetic Mobil1 is probably the best motoroil you can get. I would guess others followed up but Mobil1 was first in the mid 80's. I've never had motor problems with oil, but I fastidiously cahnge it every 7-8k miles.

That “timing idler” is a speed step down pulley. Probably 1.5x speed reduction based on sprocket size. This allows the cam sprockets to be smaller than if they were driven directly off the crank. This helps with packaging and allows the cams to be closer to each other, but based on the valve angles these cams are spaced far apart from each other.

Little tip for getting to the head bolts without taking the valvetronic apart, if you use a wrench to turn the cam you can sometimes get to the head bolts without removing the cam, did it on a b58 a couple months ago because I didn’t wanna take the valvetronic apart and it wasn’t too bad. hope that helps for next time 😁

Why the hell would you design the timing chains into the back of the engine FFS.?

Trivia: the old Subaru engines (EA79 block) had straight cut gears for timing at the back of the motor. With that set up, if you lost timing you had other problems to worry about.

Honda VFR interceptor v4 engines also had cam gears, except the later versions.

I daily drive one of those. 79 Subaru DL with an 87 JDM EA71S engine. That is the engine for the FJ1600 mini racecar. High compression big cam. Was missing its dual carb intake when I got it so I ported an 81 EA71 intake, made an adapter plate, and attached a Holley 1904 1 bbl carb off a Ford 200 inline 6. Also runs a Denso alternator off a Suzuki Samurai and a GM HEI module for ignition firing a Ford TFI coil and a set of Champion N19V surface gap plugs. All first gen 4 stroke Subaru engines use the gears, from the EA53 to the EA81. The EA82 was the first that did not.

Thank you. Good to know this failure was caused by human error and not poor engineering

Thanks for the teardown!

That timing chain design including the crank pulley/vibration dampener is identical to the M57 3.0 diesel. N54/55 have cartridge rail for the chain. This is much easier to time and avoids the old crank hub slippage. Where the idler pulley is on B58 is where the diesel HPFP is located.

very interesting. But why would BMW add the chain on a gas engine? Seems like extra parts not needed for an inherently balanced engine. Also adds costs and rotating mass. Curious. Mr. P

@@jannehokkanen8175 What is kvg? High Pressure Fuel Pump not located between Cly-5 and Cly-6 and driven off the exhaust cam? Do not understand your post other than....yes Diesel and "gas" engines share same architecture. Oldsmobile did that in the 80's....did not work out so well. Diesel pressures vs gas very different.

The bmw b58 and the Australian built ford 4.0 Barra would have to be 2 of the best later inline 6 cylinder motors out there. Being there's the lack of evidence of water intrusion I would be leaning towards a severe over boost condition which is what likely caused this failure. When a severe over boost occurs the engine will lean out and also have severe detonation which results in insane cylinder pressure's and with all combined will bend even the strongest of conrods and hypereutectic pistons can break in in many ways due to how brittle they are it's a shame to see this motor in this condition. Awesome video as always mate keep it up 👍

It was a meth injection kit placed in the chargepipe. Seen this happen a few times, it’s always 5 & 6 that blow.

@@Enthusiastlist I've heard previously from Mr. Richard Holdener that meth injection in charge pipes do not distribute evenly to cylinders which could certainly cause what is seen here. Without the meth getting to the cylinder the heat could close the ring gap and break the piston and the rod.

Sorry to hear you hurt yourself. Hope you get feeling better, I know your a trooper and would put out the videos anyway.

I just want to say you are AWESOME!

Very cool! Tore one of these down when I went to Toyota GR Supra Training. Very impressive engine.

I didn't get to go to any of the training for the Supra before I left my yoda dealer but seeing the timing moved to the rear definitely lowered my already low expectations of it being a bmw.

This is the perfect engine to take apart in the backyard. I can envision it now hunting around half the time for "some damn thing that just went flying off". Apparently the Germans are still planting mines just in engines now.
