Add "N73 plenum removal" and you will get more hits. Thanks for the videos. You are the only one showing work on N73.
Maybe but the N73 is a pretty rare engine so not many own it👍🏻
Hi George, speedystig here, ended up buying a 760Li myself, and have been through the same process this year replacing all coils , sparks and PCV valves to hopefully cure a misfire. I recently did the fuel filter too and that made an improvement. Process of elimination leaves me at the fuel pump diaphragms as these will take hammer over the years in high pressure pumps. We have similar setups on our Bottling Fillers in the brewery I work at , delivering beer at insane high pressure and speed, and the diaphragms are replaced annually on 12 month outage! Going to do the HPFPs off the beamer with some of my technicians and try some teflon material in them. Will update! Cheers for the videos
Such an in-depth video. Nobody is doing work like this on TH-cam.
Appreciate it man, takes a lot of time to do these kind of videos👍🏻
Carefully spray a bit of brake and clutch around where you think the vacuum leak is. If the revs rise you know you've found it!
Like a WWII Spitfire plane massive engine.... I'm a dieselist but I shall say It Is a spectacular expensive masterpiece!
Bmw replaced all my 760 coils about 10 years ago under my warranty. One failed 2 years afterwards and another failed last year. In both cases it was semi fails starting with the odd missfire. In the first case the missfire was reported on the wrong cylinder, so a second coil was replaced , in the recent case it was reported correctly at least statically more errors on one than the other two in firing order.
BMW wanted 900 pounds to do all of them...
Jeez
That plenum wouldn't look out of place in an Alien movie, HR Giger vibe. BIG job... everything seems mammoth on that beast! Well done for bringing it up to scratch 👏
Haha cheers Bryce! This engine is in a couple of Rolls Royce’s too👍🏻
You don't need to gap new plugs but you still need to check them for the correct gap. They will have variations at the factory. The only reason they don't want you gapping new plugs is because people kept breaking the tiny electrode on the platinum and iridium plugs. You can and should regap then to the manufacturer spec as long as you use the correct tool.
Delicious video! Can't wait to get my hands on one of these N73s! I did some research on the fuel injection system, and found something intresting. Maybe worth considering because i've seen many people doing it: replacing the high pressure fuel pumps diaphragms. It's not difficult to do, and they are prone to leaking especially on older cars.
Good luck, and again, congrats on 50k!
Thanks man. I do plan on doing those if I can find a supplier👍🏻
@@GeorgeAusters The diaphragms are very hard to find because BMW in their infinite wisdom does not sell individual diaphragms nor do they or bosch share the OE material used for the diaphragms. So there are a lot of junk diaphragms that are being sold that do not last more than a few hundred miles. Only way to get good diaphrams is finding someone who was able to source OE-quality material and custom make their own diaphrams. I found a 760 specialist locally in Los Angeles that rebuilt mine (I know I got extremely lucky). There is a guy on ebay that claims his Diaphragms are custom made to meet and exceed OEM specs but it's around $250 USD for just the diaphragms and o ring seals. His name is aavius or something like that. Worth a try over $5000 for the HPFPs.
He left us on a Cliff hanger !!
Enjoyable video mate. Hope the thumb is ok 👍
Thanks mate 🙌🏻
The date on the coils is usually YY-MM-DD format, so your 17-07-25 is 25th July 2017
Ahh makes sense.. Maybe they were replaced when the spark plugs were last done then!
Hard work George but worth in the end mate 😎👍🏻
Yep definitely!
Put the old diaphragm valves back on. See if noise goes away.
picture`s still blurry mate , is your lens dirty on camera ?
Doesn’t look blurry to me mate?
when your in your garage, and it`s focused on you, it`s particuarly noticeable, it`s not terrible, it`s just not really clear and i notice things like this as i`m a fussy old git 🤔🤔🤔🤔
I can notice it also. Not massive but I agree it is noticeable. Almost like the video is slightly over compressed.
@@t5jerry Looks like the camera is trying to focus
@@cloudCB168 agreed.
If you think a e65/66 760 engine bay is tight try a W12 GT Speed 😂
🙌🏼
Love the video. Very informative how to take apart the N73, literally uploaded right before I need to do a full tune up on my 760. If you have a list of all the part numbers you used for the crankcase breather lines/valves that would be super great!
So if I just wanted to replace the spark plugs and ignition coil, I'm trying to minimize how much stuff I actually have to take apart...What was actually necessary for this job?
Pretty much everything I removed👍🏻
As for the vacuum leak , did you reconnect the pipe that goes up into the bottom of the manifold when you lowered it back on? There is a pipe that feeds up part of the vacuum system myself and my dad nearly missed it on reassembly!
There wasn’t one on this👍🏻
it`s also and has been (for a long time) very noticeable on close-up`s , where the camera struggles to focus, not sure what phone you or your mr`s have, BUT if they`re recent flagships, with good cameras, you could do a 1 minute session to camera in your garage, comparing your camera against your phone, play it back to yourself, and i KNOW you`d see the difference, NOT criticising, cos your vids are great, merely trying to help....................
That’s strange because I can’t see any problem with the focusing on my end. I use a Canon 90D which is far superior to my 8 year old iPhone haha!
@@GeorgeAusters hate to say it mate, but you "may" need to go and see the spekky doctor, all those punches to your head in the ring 😮😮😮😮
have you ACTUALLY picked up the camera and looked REALLY closely at the lens, you`d be amazed at how many people just "glance" at the lens and don`t clean it properly, also, it`s not just me pointing it out to you ?
6:58 *insert Peter Griffin hurting himself"
😂😂😂
But I already hit the like button 😂
Appreciate the support as always mate, thanks 👌🏻
@@GeorgeAusters no problem mate keep up the great videos!
How about the stalling problem with this car...?
That was on the E46 320D that I’ll be working on this week👍🏻
Hi wot happening with the £500 car ???
Back to working on it this week, just needed some time to focus on other projects👍🏻
@@GeorgeAusters cool looking forward to the vlog 👍👍
Hopefully you just left the Dyson on on the back seat....
I'd guess that screeching noise is a faulty crank case breather valve(s). I saw the make you had, I know where that make comes from, and I have had one or two issues with the quality of that aftermarket brand. I've used Meyle in the past on similar generation BMW engines and not had a problem.
I used Vaico on my N47 and never had an issue👍🏻
Great work young man. Your probably aware of this 100% BMW. You Tube channel "M539Restorations" See you in the next one. 👍👍
