In today's episode, I cover the skimming of the engine block, sourcing big end bearings, rod bearings and camshafts and installing the whole lot into the M70, along with new piston rings to boot.
Im currently about to rebuild my m70 for my e34 touring project. I cannot say how helpful this video has been in preparation. Thank you so much for all the detail! I watched every second. Cant wait for the next.
WOW steve what an educated and well informed video on building the bmw 850 engine I have a fast lane magazine from 1991 stating that the bmw 850csi is a techno missile also did you know George Michael had one lovely car lovely build you deserve a Guinness mate after that video 👍👍👍
He's back, with 2 HOURS OF BMW FIXING GOODNESS!
Amazing video! Please don't worry about making your videos shorter, for me the longer the video, the better. You are so knowledgeable and thorough, it's truly a treat to watch your videos. I feel like you should be a professor at a trade school. Really looking forward to your next video!!!
Blimey what an episode well done Steve. Just wait till you hear the whirr of the starter motor to start it up for the first time though 👍👍👍🙂🙂
Fantastic video Steve! Looking forward for Ep.15.
Didn't think bearings would be so hard to find, yea it's 30 years old but I imagined some other engine must've been using the same size but glad it worked out. I guess I better stock some for the rebuilds I'll be doing in 20-30 years lol
God bless your damaged heads and you... I find you have to find a mentor shop, but in my town I have not found one. Over time I think you can find what you need. I’ve owned M70 and 73 models. These engines can be found in junk yards at times or purchase a lower milage 750 for very small money. These cars can cost a ton of money to maintain unless you do some of your own work…great video thanks for the education
I’ve been checking your channel every couple of days and nearly lost hope at some point, but here it is!🎉
Fascinating video Steve. I just put together a frankenmotor v8 for my e30 using m62 bottom end and m60 top end . Your video popped up in my feed and i really enjoyed watching it. All the best
Well done Steve, love the detail and time spent editing the video. Hope to see you team up with Sreten one day. 👍🏻
Brilliant video , many thanks !
Mix matching bearings is completely normal and in fact is a standard procedure on the newer bmw engine such as the n57 3.0diesel. Ask me how i know 😅
Wow Steve competing with Sreten's V12 rebuild, brave man 😂 hopefully you get the same 462k views he has 😂 Great to see you back, bet this one took a while to film! I'm saving this one for a nice cup of coffee after lunch 👌
Hi Steve. Thanks for the great video. Just glad that you're fit and well, one wonders sometimes with long gaps in the uploads. I am struggling with my 840 restoration, there seems to be a lot against me. Primarily health, I'm 71 now and too ill to work on it at times. Also, a problem with the fuel rail has stopped the job in it's tracks. I appear to be the only person in the world to have had this problem according to the forums, which I just don't believe. It's a shame the camshafts were so bad, one can only suspect a bit of bad maintenance history. Love the new old stock panels. I looked into buying some for mine but just couldn't afford them. Parts are being discontinued for the E31's left right and centre, fuel rail for one. And like you say, 4 companies all over the world have all taken my money then failed to supply and sent a refund. Each time it happens wastes loads of time. Anyway, let's hope she runs on all 12 when it's all back together.
Sorry to hear that, there is acres of experience online with the M60/M62, I hope you get it sorted!
@@stevesbmwbarn5706 Yes, you'd think so, but there's also a lot of bad advice out there, it's a matter of separating the wheat from the chaff I'm afraid. I'm currently on the last experiment with the fuel rail, if this fails then I don't know what else to do. If you're interested, and there's no treason why you really should be, I have posted threads on the Bimmerforums 8 series forum on the subject.
Instant like; now going to watch the episode. Great to have you back!
Glad to see you’re still chipping away at it mate
Super stuff. Great to see you back!
Brilliant step-by-step guide Steve. I may have to do this job someday.
Beautiful engine! Thank You for sharing!
Great video. It looks like you just got there in time. Does't bode well for someone trying what you are at in 10 years time. They would be really stuck. I've a 944 that I need to refurb. You give others like me encouragement.
There's lost of great info out there on the Porsche forums, all the same principles apply. Thanks!
Downward force of the mass of the crank + force from firing stroke will cause more wear on the lower main bearing halves.
Correct! 🫡
I've got a 911 engine in my living room, and a disassembled one in my dining room!
Been following for a while, my '91 850i has been sitting for a minute. Still runs fine. Just needs some suspension and a rotor. My car has 90k miles on it, so hopefully it's gonna last a while. Interior is trashed unfortunately. I have the inside gutted.
Hate to tell you this Steve but the blocks are alusil. After honing them they need to be acid etched to remove the aluminium and expose the silicon. If you leave it with exposed aluminium from honing the rings will snag and it will seize in time.
Please watch that section again, the process I followed does exactly what you just described and is a tried and tested method.
I’m no expert but my 750il (88,000 mi.) oil consumption is minimal, perhaps 1/2 qt per 4,000 miles using fully synthetic. The car was severely overheated and driven on a long drive after the fan exploded. Seems good as new…engine is very forgiving and tons of torque!
the longer the better
Did you have the heads ported for better flow?
Correction damaged block face. Regards
You could’ve cleaned the pistons in ultrasonic cleaner or vapor honed them
Certainly could of, but not to hand and not really necessary. 🙌
Appreciate your videos, but they sound like gamble to me. I’d have second machine shop check everything and do the work. Aluminum block and no steel liners not a good idea to me
Good old BMW and NLA parts.... :(
He's back....well that's my evening sorted! You should post an update every couple of weeks Steve.....even if there isn't anything going on and your waiting for work to be done on the engine....find a little job around the car or interior job, or something to keep peoples interest and the channel growing
Yep, that's the plan 🙏
Just Awesome! @junkm6
