In episode three, I being removing the engines fuel and ignition system, as well as the intake manifolds.
The car needs serious work, from paintwork to suspension work, brakes and engine work. And lets not forget the interior!
Follow along as this car gets returned to its former glory.
I have a 1988 BMW 750iL powered by a similar engine, an earlier M70 (pre-facelift identified by the oil filter canister off to the side instead of the front center as identified by your later M70 V12. Electrical issue prevents starting my car. Thank you for posting these videos. Subscribed with a thumbs up. From personal experience, I'm not sure you're going to be able to get away with just applying sealer to the face of the intake manifold gaskets and here's why. This type of rubber not only dries out and cracks with age, but as it ages, the cracks multiply and the rubber gradually dries out, shrinks and contracts. This has a tendency to make chasing cracks a whack-the-mole game. The rubber is going to contract away from the sealer and will continue to dry out and crack. I would recommend testing the rubber intake manifold gaskets individually. If the rubber is still soft and pliable and not cracked, you might be able to defer replacing it for a while. But if it's dried out, cracked, or brittle, that gasket is done and will need replacing. If it were me, I would replace all of them just to be done with it, but if you don't mind having to come back and chase vacuum leaks all over again later when the rubber dries out and contracts from the attempted repair, you can get away with replacing one or more at a time. These are sealed engines and don't like vacuum leaks, so unless you replace all twelve of these, I'm pretty sure you're going to revisiting these intake gaskets again. Signs of a vacuum leak include a wandering idle, driveability problems, stumbling while idling, and a potential loss of power due to unmetered air leaking into the system through the damaged rubber. I would also advise that this isn't the end of the dried and cracked rubber you're going to be chasing. Other failure prone items include valve stem seals and the hydraulic valve lifters. The M70 V12 was a glorious engine when it ran well, but when it's neglected by a previous owner, it's typically not cheap to undo the damage. Intake gaskets, valve stem seals and hydraulic lifters are the least of your worries. If that's all that's wrong with it, you've dodged some expensive bullets. It's damaged camshafts, cracked coolant pipes and broken valvetrain parts where it really gets expensive.
Yesterday I had two of the four fuel rail ( mine are 5mm allen) bolts that wanted to round off . I was able to use a small punch and hammer to tap the base of the bolts and unfreeze them. I got lucky . Working on the older cars is like surgery- everything is fragile and it can get complicated in no time if you’re not careful. BTW, You’ve done an amazing job with your 850. I hope my 91 850/6 comes out as well as yours did. 👍
Keep up the great work. It seems like you just started this Channel and you already have the quality that experienced youtubers use. I hope your channel gets big good luck.
Loving this channel together with m539 restorations!
Just stumbled on it -and like it. But beginning with "Coming up" and a bunch of other elements from M539 feels a little unoriginal to use here, tbh.
@ Are you going to say that "hello" is copyrighted also just because you've heard it said elsewhere too? Same principle.
@@houseofno Not really. Starting a video about restoring a BMW with "Coming Up" was no coincidence. Saying "Hello" isn't comparable at all.
Good man. That's a big job in anyone's money. But you're as well doing everything now and have it done. Best of luck.
Great work Steve am really enjoying these 👍👍
Awesome and interesting video. I was glued to every minute of your work . Looking forward to more videos . The pleasure of owning a classic dream bmw is worth the pain . Keep up the awesome work. Greetings from South Africa. God Bless
I have same problem to fix a customer car today bmw m70 intakes manifold but am happy to see it here thanks boss
Thank fuck that bolt came out, felt your pain 🤣 don’t know how far along the build you are as I’ve just started following you, but Irwin bolt extractors, wera brand hex / star keys or a pair of knipex cobra’s will change your life for the better.
I found gold :D
Good work Steve, but please get an external mic and sometimes I can barely hear you! Keep up the good work!
At 7:08 and 21:48 - you removed the same hose twice?
Hey, nice vid, but I struggle to understand some explanations. Where would the overpressure in intake come from? There is nothing but suction forcing the air delivery... there sure is difference when idling and under load but I doubt there ever is an overpressure. One more comment - probably just a twist of a tongue, the fuel is not sprayed into the cylinder but rather on the intake valve and then sucked into the engine :) These engines (inc M54 etc) are all indirect injection...
Ciao Steve, possiedo una bmw 850 e31, quante bar di pressione carburante monta? Xché il meccanico mi ha adattato una pompa, ma cammina frenata, esce fumo e pressione solo da una coppia di scarichi, andava benissimo l'ho portata x un motivo e mi cambiato la pompa dicendomi che dopo anni va cambiata xché andava in corto...mah secondo me la presa lui x le sue gare... Grazie attendo sapere...
Steve, am about to buy a 96´bmw 850csi, just wondering what to look for before the purchase, or maybe what are the most common issues for this car.
There are OTHER KZhead videos devoted to this, as well as online articles as well. Happy hunting and good luck.
I thought all those bolts were behaving much too nicely for a 30 year old car! Good prep for the suspension I suppose
Yep, the anti-seize gods were looking over me!
Coming up? Can you at least create your own phrase to start your videos?
It's not trademarked just because someone else has used it. Next thing we know you're going to tell us that "Hello" is copyrighted too. Don't like it, don't watch.
