Figuring Out What Happened to the BMW E31 840's M60 V8 Engine | Cheapest E31 8 series in the US: Pt1 

Another interesting one Josh, although not a massive amount to show at this stage. Any marks at all in either Alusil or Nikasil are bad news, whether you can feel them or not. Cant' say for definite obviously, but the crosshatching on either Alusil or Nikasil is a very specialised job, not impossible, but quirky, and the fact that it is so obvious on that engine may mean that someone has given it a normal honing which will have wrecked the coating. New compression rings would mean that the compression figures will be OK to start with but the engine will always burn oil. You are doing the right thing with the M62 swap.

If you're looking for bottom blocks, you should try to get an M62B46 Block from an X5 4.6is. That extra displacement helps!

Interesting to see some coverage of the E31. And curious to see what the source of the oil blow-by will be!. Looking forward to a great 2024!

Exactly the same project im doing right now with my e30 v8. M62b44 non vanos bottom end m60 top half with standalone management Dont forget to blank the oil feed hole that used to feed the U guide on the 4.4 bottom end. I drilled mine, tapped a thread and used a bolt with locktight. If you dont, you will drop oil pressure. Lookign forward to more uodates mate so ive subbed 👍 Im pulling the 4.0 out if the e30 tommorow actually Cheers Ant 😎

Hell yeah brother. I have a 1995 M60 E38, love to see this!

Hope you can send that block for repairs or buy a new block :)

OSV or oil tube o-rings.

Excellent…

Is it hard to come by the E39 diesel 6-speeds in the US? It's a popular swap in Sweden for a much stronger gearbox if you can find the adapter. Excited to see an E31, my neighbour used to have an 850i when I was a kid. Our windows would shake when he started it in the mornings :)

Yaaaaaaa Justas!!

M3 josh the American M539 🇺🇸

Jeez, lying under cars fighting with exhausts, driveshafts etc. Like me, you really, really, REALLY need a 4 post lift. I have a Z3 breaker to take apart. Picked it up Friday and I can't face it just yet. I'm too old for it, I think. 😂 6 speed? Nah. The E31 is a tank and better as an auto. I don't think a white 840Ci will be worth enough for many years to warrant a $4000 swap.

just another 9am watching engine tear down, nothing to see here 🫡

Excited to see the E31 build. Such a gorgeous body style and that pillar-less look with the windows down. If it’s not going to be a keeper, I say leave the manual swap for the next guy. Especially as I’m working on my neighbors 850i as well. It is a huge mess that has been fighting me along the way. But I have a couple weeks break as it just went off to paint and body work. Would love for you to check it out on my channel. I told him a few more repairs and I’ll be able to afford my own E31 😂

Did you say m60b44? M62b44 bottom end and m60b40 cylinder head? Sounds like a fun project

Please document the B44 build! I have a m60 in my e36 and would love more power!

Nice Video, I enjoyed it Josh. German Engineering is top notch, greetings from Austria

could those marks be caused by improper ring end gap?

suppose it's time to figure out what's wrong with my 840Ci too. I bought it a while back and it's making a pretty nasty scraping noise from the timing cover/head area. Can't see anything from a visual inspection, but it sounds like the chain is scraping.....something. nothing in the oil pan as evidence. I have a M62b44 sitting here, might be time to make that hybrid alongside you.

💪😎👍

Eustace is the man yo!

You should m60 swap an e30 for a video and I’ll buy it from u lmaooo I’m in IL too

Beamer fan till I die...❤

L s swap

Happy new year to also, i allways see you video before i sleep.when i buy my bmw e34, 4 years ago and i had to find out something i didn't show, you were the first video that came up and it solved the problem and i still have it to this day🎉🎉 in my opinion you have the best olde bmw content on RU-vid keep going 🇩🇰🇩🇰

Hey bro

Happy New Year Josh to you and your family, wishing you continued success and much happiness dude! 🙏😎

Nice video my friend. Cant wait til u do an s54 in the dakar e36 😅

Another great learning experience for all. Good new year start.

another E30 ALPINA? Nice :D

E46 or 350z or Acura TSX or FG1, Fg2 Civic Si? Which would you choose? I am buying a car soon had an e46 btw about 4 BMWs love them lol

You can find a 6-speed 540 E34 or 540 E39 and take almost all the main 6-speed components from there. It should not be that expensive. Back in 2017 I manually swapped my 540 E34 with brand new clutch kit and flywheel and a trans from an M5 E39 and the entire cost was about 3K. But if I were you I would put an S85 with a 6-speed gearbox in the E31 and have the perfect BMW!

Oil separator failure most likely

Very interesting. Happy New Year!

❤first ❤️

Piston rings mightve been sticking

Good Stuff! @junkm6
