This is so professional, very nice work. In my work I have learned one point that anyone building an engine should take note of, on some engines do take care of the amount of sealant used, sealant squeezes inside of the engine as well as outside, a simple wipe of the outside of a joint tidies it up but don't forget the inside will have the same. In the past I have seen sumps full of lumps of silicone sealant and cam oilways blocked.....not Porsche I am sure these guys are aware and it is not a problem for them, but anyone building a motor pls keep it in mind.
hello from Delaware USA at 9:00 i am curious due to the design of the fan shroud, do the forward most cylinders run hotter? i bet they do if you use a laser thermometer on them, but how much ? Just curious . Looks and sounds fantastic by the way .
The engine has a shroud over the fan metal and ducting that directs the air over all the cylinders to cool them, the fan is not jus blowing undirected air around.
the flow of heat dictates oil in a vacuum environment. pressure is just the fluid travelling to bearings, the rest is thermal dynamics. if you notice, the exhaust pipe heat gets sucked backwards to the top.. even the very old subarus run like this.
Well, nice film to show the kind of work they do. I am sure it was not the final assembly as I did not see any oiling during the crank, cam, cylinders to pistons etc. Also I hope there was not any bad scratch-mark done on the first piston when the ring tool was released... Any way the film time is way too short for real engine assembly as it should take much longer than this to just fit and measure tolerances of pins,to rods, ring gaps to cylinders etc detailing before final assembly. Good presentation and clean environment though. :)
Yiannis Loukopoulos I noticed that too, I expected to see the piston rings well oiled and the cam with assembly lube, that is especially important during cam break-in for US modified engines as well as oil with ZINC for superior protection
Maybe not so expert. When the two case halves are assembled the rods have to be on the crank. Unless I missed it, I didn't see the rods on that crank when it was lowered in. So they must have dismantled it and installed them and wasted some more sealer. Then started filming the pistons being installed… Anyhow on the few Porsche and VW air cooled engines I've done that's how I had to do it. Complex, over-rated, and EXTREMELY expensive engines to rebuild.
Yes the rods should have been installed on the crankshaft prior to being laid in the case. As too the rest of your critique I must disagree respectfully.
Doing a couple of these in the early 90's, Andial recommended and I used, Yamabond (Yamaha motorcycles) on the case. They used it in all the race motors they built (they would disassemble 962 motors from the factory and then go through them) so I did too. Also used the same grease used in industrial cooking ovens, to pack CV joints for racing.
I am a college student in the US. I would live to work for the factory it stuttgart building porsches for a living but scared I might not make money. If I were to really do what I want it would be this
No, but if a car sits for some time, the film of oil does find its way to the bottom of the cylinder, and at startup, you can get an initial puff of smoke, that goes away after a few revs.
Careful control of oil should be equal all around the skirt... But gravity shows this to be wrong.. Just that little amount touch does create this flat spot... Newer , more precise cutting and pre grinding can eliminate this all together.. Down to the 1/10000 of a degree.. Isn't it great to be alive during such changing times....
lol I haven't seen anyone as yet say that till you. Although that is not a word in German...or any other language. I know this from some Germans who straightened that out for a group of us some years back. But thank you though...got a good laugh out of it anyway. Well played sir.
captkilt Thanks Mate. Don't you remember the old VW Golf GTI commercials from here in the states? Back in the 80's to my memory. There was another bit where a bloke took a GTI for a spin around maybe the Nurburgring North-schleiffer circuit and said, "Aye She Vice Vakken", or something similar to what that sounds like in American English. I don't have a clue what that means, but I assume that the phrase means that the driver "enjoyed himself". By the way, I have a website that showcases great race car sound audio clips from events here in Northern California. Please visit www.theracingear.com and let me know if you have any feedback. Thanks again.
@@d.martins709 i think thats because there was no carbon fiber in the old days. I think you are right. Carbon fibre should be better than fibreglass in every way.
Having done a number of these, I have to laugh at the lack of detail omitted in putting an engine like this together. General idea, yes. BUT do NOT follow this as an example of the way to put it together.
Yes, the rods? Not impressed. (ex racer and 911 owner) I see that there are many mechanically naive admirers though..... but many that aren't fooled either!

911 logic ahhh porsche people... so stuck in their ways. Maybe that lump won't leak as bad with orange goo? Did that ever occur to you?
911logic, that Orange Crap is not silicon, it is a special anaerobic sealer that the excess diluted with the oil.
Note on the sealant:

@@wyattcave1752 yep yep. duly noted. Watch that sealant. Expensive rebuild for sure.
Magnificent. This transcends culture and language. Total respect Mittelmotor GmbH.
It was so delightful to watch a master craftsman do his work. Greetings from Australia
I'm very impressed about the attention to detail.
Germans know how to work & play at the same time :)
my neighbor had a 1967 911s with this same motor in it and it sounded spectacular!!
My God, absolutely beautiful sound
I tough the same even at high revs the sound is sweet,..,
Brilliant 👏👏👏. A work of fine German art😎🇦🇺
Estos tipos son unos Crack. Like
FANTASTIC!!!!
Where engineering meets art.
wow, excellent workmanship
work of art!

Einfacher ist es den kolben im zylinder vorzumontieren und dann nur noch am pleuel Bolzen durch ✌️

Very gratifying video.

Simply beautiful.
Obviously the way the 911 engine is designed it was meant to be removed from the car to do any major maintenance.
Beautiful!
It looks like they forgot the alternator/engine harness. At 17:08 it's not installed. That should have gone on with the shroud.
Dream Job.
uauuu awesome job boys

this is so beautiful!! I'm in tears!!!
Puede verse como sale el combustible por las mangueras en cada una de las tomas de aire!!
Hey Fritz you forgot the connecting rods!!!!!
Unless they installed them later, not the usual method of assembly.
what about measuring parallelism of the camshaft gears?
Wish they showed the power output! Sweet Engine though!
North of 300hp!

1.45 Вкладыши они че не смазали перед установкой?
thank you for share!
I need one of these for my Aveo, and soon.
muy profecionales

I don't want much in life,but I really want a 930 turbo
wo seid ihr ansäßig? könnt ihr euch mal um meinen 930 turbo (wls) kümmern? der lader macht komische geräusche.

Your going to heaven.
does the bore of the Porsche engines wear more on the ground side. due to the bias of gravity?
No, but if a car sits for some time, the film of oil does find its way to the bottom of the cylinder, and at startup, you can get an initial puff of smoke, that goes away after a few revs.

cual es el nombre del pegamento q usa para la tapadera?
Permatex, sellador anaeróbico
Really needs a hood or suction for that acrylic dust. Shew.

Hemi pistons...high flow heads... there you go
Holy cow
how many cylinders?
6?
yes boxer 6-cylnder engine, naturally aspirated, single overhead cam 24-valve
2 valves per cyl, not 4
Hmmmm..high speed die grinder on fiberglass with no eye protection. :(
If professional watch makers use gloves when assembling watches, you guys must do the same

le calage des arbres a cames il le fait a la révision des 10000KM
hard work 😓😓😓
HP?
300 bhp 2.8 litre
I havent seen not even a drop of oil in the whole assembly process, which may be a little concerning.
+1. .. Took notice as well. .. As the saying goes, .. we'll fix it in Post.
3:10 oil....
We don't need no stinking oil!!
Bildfolge zu schnell.....schade
ben jour es co. je peut. c. voire. comment. fenction pense avide pershe karira
how long will it last until next rebuilt? why not just slap-in a disposable engine that made in China or india?
It is about design not where it is made
Volvo made in China
Mercedes made in india
FAHR FURG NOOGEN!!!

porsche bomba Ma .
95% of the armchair commentators on this channel ,I would not let assemble my rusty bike !.
The red one is slow.
Why that ugly fiberglas air housings ?
Light weight. Just like all the 60's racecars (e.g. ...908, 917....)
RSR engine. fibreglas is lighter than metal
@@d.martins709 i think thats because there was no carbon fiber in the old days. I think you are right. Carbon fibre should be better than fibreglass in every way.
So many armchair experts.
Absolutely.I have found that life is much more enjoyable if you find less of it to criticize.

+norincobro What about the rods?
themanwiththekx They probably just skipped that part in the video, obviously not in the assembly... That doesn't mean that they didnt do a good job!
does the bore of the Porsche engines wear more on the ground side. due to the bias of gravity?
Good question. I don't think it's a problem. I know a fair amount about Subaru engines (very similar) and this is not a problem.
