Your good by me. Just keep doin' what you're doin'.

Thanks for all the hard work Nathan, I really appreciate it. I can't wait till the rod bearing job is done and hear how she sounds. See you next video.

This is the best combination of videos I've seen covering rod bearing installation.

Good job! You are fearless, man!

Thanks, Nathan, very interesting, quite a beast of an engine! I admire your perseverance and skill.

Been looking forward to this one! 👍

Your so helpful on ur videos when I repair my 2000 528i. I've owned it for 4 years. I'm on disability and wish i could afford the channel for the monthly fee. Your great thanks again . Love all ur videos

No prob with schedule, mechanical work vids, or heavy breathing. Keep doing what u do.

I've been wanting a s85 for a while now. I was about to buy one 4 years ago but I have found a really awesome deal on a n54 and I went that route. But this is pretty much almost the same to my e90 n54.. my belt shredded so I did all this pan out, got new everything from that point.. I'm definitely going for a s85 again. Awesome work bro!

Cant wait to see the new bearings going in!

tops are probably worse since that is the most stressed one also the caps should have a casting number that matches the caps to and bottom i know the e39 m5 does

Another great video. Love the detail and thank you for posting! If not too late, may I ask you try to pictures the bottoms of each bore (piston up). Have seen some engines with bore wear and gouges along bore.

Excellent video Nathan 👍stay safe over have a great weekend.

Great vids and info!

That’s why I loved my E34 Euro M38 engined M5. None of these problems!

It would be very interesting to plastic gauge the bearing clearance before and after the install of new ones Coincidentally I have resized literally thousands of connecting rods and the wear patterns are consistent with out of round bores

👏🏻 good video.

Damn lucky! 100% agree. It's a ticking time bomb that should NOT be ignored.

Thank you sir for taking the time energy finances to share with us how to fix these BMWs. I’ve been a fan for years and owned several but after my E65...I doubt I will ever own another BMW. Maybe a slow I6 non-turbo one down the road. I do watch your vids to learn how to maintain these cars and what to expect again with another BMW.

like what you share, I own two 530i and one 540i. 2004,2002,1994

Nathan's I hate to say it but it looks to me like you need some of the polishing sand paper that has been used for years on American engines as well as why do these engines have problems with rod bearings and at what mileage do they usually start having these problems please? Thanks alot man. Love the channel

Hi. Are you going to be upgrading to the newer style piston oil squirter?

How would you go about removing the top rod bearings?

You’re rite we sit at home waiting ready to choke you 😂😂 keep the videos going my friend

@17:28 Interesting cap connection surface on both ends. How they do it? I think they call is Fracture-Split.

I don’t own a M5 but I enjoy this video.

Do the crank journal bearings wear or just the rod bearings?

Nathan, swapped a motor into my 02 525i . It started once then next week i went back to finish up installing cooling system, I went to start it and nothing , I’ve had my batter recharged and bought new starter and ingnition switch. Still no crank no start. Any ideas

Sorry for two messages..but what about a inspection on the mains

hows the big end bearings? since you have easy access to it, why not check it out

This job is NOT gonna be fun on my driveway haha!

You Did Rodbearings!👍 Now Do Main Berings in Side 👌😁

how many miles on this engine before you changed bearings, great channel

What was the knocking noise from then??

Can you replace oil line without pump removal?

Great content! I am with you since the very beginning and can't get enough of the good content that you are sharing... keep up the good work! Question- where can I get a good ISTA software for my E60 M5? I had a problem with my alternator that caused a Low oil pressure code and after changing the alternator and a new oem bmw battery, this code is still present (after deleting all codes). Any advice? Thanks!

What is a normal lifespan foe barring a if they are new with oil changes every 4-5k miles?

I was looking forward to this video. What a job! Was it lack of maintenance that caused the bearing failure. Looked like it on my phone anyway.

Great video, I'm about to also do my rod bearings on my M5. Are you doing then 1 at a time then rotate the crank? Or doing 2 at a time the rotate the crank ? The torque process is really something to

That looks like something I want to try myself. Except I don't have a lift. I'd hate to do this with the subframe in the the way lying on a creeper.

it's always a tuff call to buy only one tool (you need at the moment) or a whole set. you indeed a warrior. I would have smashed the T30 screw-driver handle to obtain the extra length and bought a new screw-driver at my next store trip (other necessities. hoping to see some journals--any posible scoring (could not be galling or brgs would look horrible). any attempt to polish jounals?--W/croke-us cloth or finer. ?how dem valve-stem seals?

What do you think of regular oil analysis to follow rod bearing wear? Look for wear metals to help decide need for repair. Oops 😬 . You mention alleged oil analysis by someone else with no wear metals. Wish you had been able to send a sample

Nathan, will you plastigage the new bearings to insure the clearance is correct?

Drinking Game: Take a shot every time he says "funky wear"

Nathan reliability on 2015 BMW M5 and M2? Thanks

Do a manual swap on the E60! Lot of time in coronatimes

What's the crank shaft look like. Any concerns with wear or damage to watch for on it.

Great video ! One thing I noticed that you rotating the engine the wrong direction which is not recommended at all !

Forgive my ignorance, but why do the bearing caps appear to have broken surfaces, instead of a machined flat?, or am I not seeing what is going on?

Yeah I think I’ll just take the engine out when I get an M5 lol

While your there if it is easier take out starter and bench test ! I said it before and once again No Bearing can Knock on starting and not on Idle !!! You Have to at least acknowledge that ! BTW these bearing look as expected for 100K with bad Oil !!! LOL Cannot wait to see the Top Ones !

Why does the S85 have high rod bearing issues; Is it because the block flexing too much or crank is too weak?

What's with BMW's fascination with recessed T30s?

Do you plan on replacing the sub-frame bolts? I believe they're torque-to-yield...

Tyler Hoover should have called you when he bought his M5 E60 u would probably sort that car out for him without any problem He has a Alpina B7 what you think about those cars? is it a car you would work on

The top bearing always look way bad, because have way more load.

So you're ready to roll Nathan?

Are you doing the mains? On my 300M the mains were wore out as well as the rods.

You doing the valve seals also?

About a year ago we had the 'pleasure' of having to replace crank, few rods, oil pump system parts and related @ 44k miles. BMW corporate refused to do much due to past history we were not 'privy to'. My guess was overfilled oil or not doing scheduled maintenance during warranty. Was the same s85 in a M5 with low ( near zero) oil pressure and a low rpm vibration/harmonic engine noise situation. #10 rod partially spun the lower shell above upper shell. Rods 8 and 9 worn thru most all layers but had not catastrophically failed/spun yet. I dont recall if it was the chicken that led to the egg, but I do remember distinctly we were thinking 'what odd wear' on rod bearings. Bearings were clean, no striations from dirty oil, but EVERY rod bearing looked as if it was tie-dyed (yes like the shirt). I swore it was oil related but we had little history on it. Likely 10-60 oil never getting to optimal peak temps...in my case, chronic short trip driver plus long northeast winters and nothing ever is up to temp. We used oem parts, spec and oil per owner request, advised to have rod bearings inspected every 40k miles and oil metal analysis every oil change and consider a 0-40 or 0-50 oil. A dozen oil/coolant radiators dont help the situation.

Doesnt knocking mean spun bearing. So if they were not spun, they wernt knocking

Love your videos great work. Now tell me who did your electrical work in garage they did sloppy job none of your cables are stapled 😣

Visual inspection of bearings is one thing but please get out the plastigauge and measure the ACTUAL CLEARANCE. You need this information!

Lets get the elefant out of the room... whats the cost on this maintenance

My top bearings looked pretty bad when I changed mine a month ago. Your bottoms look worse than my bottoms, so I would guess your tops will be horrendous. I had 90,000 miles on original bearings.

Do the replacement bearings last longer?

Wow, what shit. How long have they been making rod bearings? Must be new technology, a prototype trial of basic engine parts

!!! DONT TURN THAT ENGINE COUNTER CLOCKWISE !!!!

How many miles on this car?

I bet you could of gott allot of fun out of this motor!

Worst dam bummer

How hard was this car driven? My God, Ive torn down race engines that after a whole season look better than your best bearing.

Good video that breathing is ridiculous tho

Conclusion = This is NOT a diy type of car, jeez' . . . it's great for content though

Watching this at 1,5x speed is not that painful, sorry but was really hard to watch when you talk slow. I really love the m5 and was interested in this repair, bcz i want to buy this in future. manual tho.

“What is that ?? Something.??”” Dudes a good guy huh lad he has fun w all this! 👍🏻 “ I pissed my self black” Hahahaha. Liqui Molly is almost black new sure it’s not Molly. Great BMW oil

I can’t believe these expensive pieces of shit don’t have forged rods 😆

People need to chill with hurrying Nathan on the m5, there's a global pandemic going on slowing down shipping for smaller businesses clean your house or workout ya simps

That’s WAAAY TOO MUCH SHIT.

I really doubt the bearings are damaged enough to be making that knock no way I did a Bearing job looking just like this no difference on the knocking noise ended up replacing the crank block bearings that was the problem

THAT is a Piss Poorly built engine!

I want to see crank journal close up, or im unsubbing!.

Just drop another motor in,..

Sorry for two messages..but what about a inspection on the mains
