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!!!
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.
Thanks for showing the valvetronic installation tool in action, I have often wondered how it works. Valvetronic is a very clever system for controlling the amount of air going into an engine and from what I understand it's also pretty reliable. FYI, these engines do not actually need a throttle body to run.
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.

@@MJPilote Actually the desmodromic system is a lot less complex than this. Makes you wonder what they are thinking- The BMW costs 16000.00 makes about 350HP and needs rebuild at 100K, while you can buy a GM 604 crate motor for 8500.00 which makes 400HP and will go 200K easy.
When originally assembled by BMW all the components in the head are graded and matched to achieve the target fitment clearances therefore it is best practice to keep all the followers and rockers and lifters as a set when removing them so as to replace them in their original locations as a matched set.
That BMW head is a work of art. I'd like to see you and your team utilizing eye protection more often, as an errant spring, bolt or milling chip will ruin your day.
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!
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.
That block would be a good lesson on how to stitch cast metals. Teach your engine guys how to repair cracks etc 👍 The method is fairly straightforward and I think it would make for some good video content for you 👍
Soak the rusty exhaust extractors in a solution of water with a couple of litres of vinegar and a litre of a calcium l, lime , rust remover. The rust will fall off overnight and it will look like new.
confused by the engine called a 'crossflow' at 7.13.mins. The block has a pre crossflow casting number, and the cylinder head has 8 ports on the same side, so not a crossflow. A cross flow has inlet and exhaust on opposite sides.
If you spray the face of the alloy cylinder heads with WD40 before you skim them you will get a better finish cut it stops the chips from sticking to the inserts and dragging the chip back over the head on its next revolution

Not when they might happen to log in to RUclips. It should up your views to subscriber ratio. You will need to tell them though. Keep up the good work.
So what would you say is the best way to prep ur race car for winter . Drain coolant or leave it in . Anything else that would help it survive the winter ?
Lee, can the cracked block be stitch welded or is there likely to be other unseen damage to the block? Just thinking it might be worth keeping for the time when you cannot get one of these blocks.
Having spent most of my working life in Huntingdon, my eye was immediately drawn to a Lola sticker on the tool box behind the BMW head. What's the history?
Lee is it me but it seems like a lot of spring pressure on the "torx head bolt" on the top rail, the hole only looks like a m6 or m8 hole, Loving the videos as always and hats off to Isaac and Paul (you have got 2 top notch guys and getting use to the camera; 10/10
@@michaelbamber4887 Hi michael, yeah i probably put the question wrong. I was more thinking of the bolt threading in to soft aluminum especially with the spring pressure behind the bolt, I would have preferred to have used some thread lock
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.
Holy crap BMW. It's like they have engineers designing things as complex as possible just to justify their employment. Any fool can make things more complex, but it takes genius to make it simpler.
Complex but efficient beats simple and inefficient. Remember the overwhelming amount of BMW's thus equipped are never likely to need this level of repair.
@@stephenscholes4758 Part of why so many don't need this level of repair is because of the stuff that could and should have been better designed has failed and is exorbitantly expensive to repair. 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.
@@stephenscholes4758 exactly this. if only idiots knew that BMW M5 with a fancy V8 is more efficient and does more MPG than a crappy Toyota Prius if driven on the track.. That's not even mentioning driver's experience that really is not comparable to any other manufacturer..
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.

Do people still blueprint engines? It was a big thing back in the day but I never hear of it nowadays. I had a blueprinted mini engine back in the 90s. Dayum that thing shifted. Used to blow drive shafts every few months. Always near side for some reason.
No need for blue printing on anything but an engine for a car racing in a series demanding a standard engine. Blueprinting just gives you a few BHP extra over your competitors; which is only an advantage if you're all running identical engines.
The oil pump on the Rover V8 can be primed by putting a rod with the right shaped end (very easy to make) down into the oil pump drive. This is then rotated with an electric drill and until oil is flowing throughout the stationary engine. Attaching an oil gauge will show it's all up to pressure. No need for anything-other than engine oil in the sump.
back in the day the mechanics who taught me would fill a new oil pump on a v8 Rover with grease, stating it won't suck on startup without it. Using a drill and attachment with a pressure gauge sounds like a better idea.
