This BMW cylinder head is a classic example of German over complicated design. Add in the Chinesium and plastic parts and it's easy to see why their cars have become a joke from a durability and longevity perspective. I feel for the poor people who can only afford to run this stuff out of warranty. On a positive note, this German strategy should keep the engine shop in work for years to come. Good video, thank you.

There is no throttle butterfly on those engines. The valve lift is variable and is used in place of a conventional throttle butterfly. Plus of course also have the Vanos variable valve timing!!!

@brarautorepairs Жыл бұрын

It is a very good way of reducing pumping loss. The engine can run without any throttling at light load. The gas pedal advances the valve lift rather than the throttle body. There still is a regular TB for backup purposes.

FYI, these engines do not actually need a throttle body to run.

Being a machinist myself ( now retired) I wouldn’t scrap the block. I would first sleeve the cylinder, then drill and pin the crack ends. Then grind out the rest of the crack. Weld it with the cast iron welding rods. Machine the deck then rebore the cylinder. I have made this type of repair multiple times with great success.

With regard to cleaning up that manifold - have you looked into electrolysis? It takes a bit of time, but it's unsupervised time (Also, make sure it's well ventilated as it gives off hydrogen!) 1) Big tub, big enough to fit part, fill with water. 2) Add a couple of spoons of Bicarbinate of Soda and stir 3) Attach negative to rusty part. 4) Add a couple bits of scrap iron/ steel and attach positive to all sacrificial bits (a couple of long bits down each side would be best - make sure that they don't touch the rusty part!) 5) turn 12v on and watch bubbles. 6) Wait 24 hours 7) light wire brush of any remaining rust and you're good to go!

I'm with you now, well once its fitted and the torque is set, a m8 in 6061 aluminium can hold around 1800lb. Aluminium threads are no good if you keep separating the joint. This is when they 'strip'. Helicoil insert or time sert are fixes if you bust the tread. We used to fit um if the part was to be removed and refitted and was made of aluminium.

Could that crack not be lock stitched? With the paucity of the blocks at some point its going to be economically sensible to attempt an actual repair, rather than just throwing it away and if a lock fixes it you got a good block ready to go elsewhere. What we need is what they still do in India and Pakistan where they cast new blocks for trucks and cars, we used to do it here in Britain, I remember my grandfather getting his Austin 7 and his Triumph Vitesse worked on by a blacksmith's in Westerham like welding or brazing his Triumphs cracked block, that blacksmith could braze just about anything and he handled things like pressing in new waterpump bearings and seals which he did for free if me grandfather provided bearing and seal pack.

Things like the CCV system, DISA valve, Vanos, cooling system failures, etc. This system itself even causes expensive repairs due to long maintenance intervals. All because of underwhelming cheaply made parts that are somehow insanely expensive thanks to that logo on them, and labor intensive to replace, or just outright cause the engine to fail. The thing is, a variable valve lift system could easily be made using a much simpler and more robust system with a hydraulic variable height fulcrum on a rocker arm. Then it's lighter, more compact, more easily serviceable, and probably quite close to the same reciprocating mass.
