BEFORE WATCHING! What do you reckon is waiting for us inside the S65 engine? Place your bets - original bearings? Copper or later updated ones? Been changed recently? About to fail?
Great video! It’s such a variation of how more or less worn the bearing are on different year builds and mileage driven. Would you attribute the excessive wear on lower mileage to be due to hard driving patterns and/or poor maintenance? • Btw, Ryan and Cat are so amazing to chat with at IND and I agree that Fall-Line parts upgrades vs stock will be the best way to go 👍🏽💯
These guys did my Rod bearings on my e93 M3 last week and they did a great job. I can honestly say I trust Evolve more than I trust the BMW main dealers. These guys don't only know their stuff but they are really friendly towards their customers. Evolve are the only company I would trust with my beloved M car. FACTS!
@@EvolveAutomotive When I was at your workshop last week, I had to leave my car with you overnight. I was about to arrange an Uber so I could get to the nearest train station in order to get home when one of your staff told me to put my phone away as he would drop me to the station!!! I'm not going to lie, I was taken aback as your fella did not have to do that. It's these little touches what will keep me and other customers returning. So not only do you get a professional and trustworthy job carried out on your car, you also get great customer service. Keep up the good work Evolve. 👍
Awesome video, it shows that these motors are capable of holding up if they receive good maintenance. Seems like the previous owner respected the car and followed the proper warm up cycle as well, which if not done could also result in failed bearings.
I wouldn’t call bearings worn down to copper as holding up...who knows what the history of the car is, but as was pointed out, if the car had been driven hard or tracked cylinder 8 could’ve gone fairly easily. But yes, it does show that the bearings can last...but bearings should still likely be changed every 50-60k miles. Probably much sooner if tracking the car regularly. What was more concerning to me is hearing that the car with only 30k miles had worse wear. Just goes to show that there is no rhyme or reason for how and why these bearings wear how they do and mileage on the car doesn’t count for much. The best you can do is try to buy a car with long term ownership and maintenance records which is pretty much the rule for any car. Then it’s still no guarantee and you better change the bearings ASAP.
@@ericm8368, these motors are notoriously know for failure due to worn bearings at a lot lower mileage. My comments were on the fact that this particular example "held up" a lot longer than most S65s. Bearing replacement on these motors are considered a maintenance item, crazy to think so I know, but unfortunately it is. 🤣
@Eric M - We believe that number of cold starts and how the car is driven whilst cold is the main contributing factor to the wear. The 30k car may have not been looked after, regularly driving hard from cold, lots of short journeys to not allow the car up to temp etc. Unfortunately it’s impossible to know how a used car has been treated in that regards. If it was directly linked to mileage it would be more simple but as this car shows it is not.
I thoroughly enjoyed watching this video. Very informative and soothing to watch at the same time. Job well done to Aston and the guys at Evolve. Can't wait for Imran to do the test drive.
Ok ok, I’m a little more relaxed now, my e93 has 60.000 miles on the clock and I always worry about this bearings, even tho I always warm up the engine and never rev it more than 3000 until fully warmed, Still in plan to change them soon but hard to find good trusty shops nearby. And great videos guys, I like this project and I’ll follow it closely, curious what you guys will do with it. Cheers
Thank you gentleman for sharing, might be a small audience for content like this but extremely appreciated, thankfully there's still some engineers and technicians out there
I’m at 95k on my e93 M3 and I plan on changing the bearings myself but every time I drive her I let her warm up for about 15 mins just changed the oil too and she runs great!
Good that you guys maintained objectivity and demonstrated how a high mileage car that is maintained can have rod bearings that don't look bad. Motor mounts on any car with that kind of mileage will see that kind of wear.
Amazing first ever video I've watched from the channel and I must say that I won't stop watching vids from Evolve...however, the background tune sounds so much like 'The Game-soundtrack'.
Amazing vlog Imran, well done to the previous owner 👍 I was dreading this being the end of the project with the thumbnail, lol. Heard so much about the rod bearings on the E92. Finally able to see some content on it and see it in action, being done. Salute to Aston mans a ///Magician legend!
Great project and vid. I love seeing these type of series and Aston is great at explaining what he is doing and making it simple to understand. Nearly at 100k subs too. I'm sure that goal will met very shortly. Keep up the great work.
Love how the oil coming from the rear plug was nice and amber while the oil from the front plug was black. Seeing how the rear bolt was not stock while the front was, there’s a possible chance that previous servicer, probably former owner, wasn’t aware of the front plug. My 2011 leaks right in front where oil pump is, another item I need to look at when I do my bearings.
Amazing series gents. Love it!!! I remember you mentioning on one of TR Hamza's videos that you were gonna do a high mileage project. I love being able to learn some mechanics like this!!
Hey guys I really enjoy watching all the things that you do with all the cars. As I have a E90 M3 and have done the rod bearing as you guys have and wanting to purchase some of the products offered and programs but, I am having concerns of the main bearing and what I am learning about the S65 vs the S85 - what are some of your guys thoughts?
Great video guys. I started a similar project about 2yrs ago. Bought an 09 on 123k on original bearings. Changed them straight away and looked reasonable, small amount of copper showing but nothing worrying. Interested to see where you go with this. Hopefully will show that a leggy e9x is nothing to be worried about.
Damn man i’m at 98k miles can’t wait to get these done one less worry in my mind. I honestly rather worry abt the trans taking a sh** then the rod bearings breaking lmao
@@EvolveAutomotive Well good to know that was a worry of mine is there anything else I should worry about besides rod bearings and the dct? Like expensive stuff yk
The rod bearings on my e92 give up at 72k and only had the car a few weeks lucky for me I bought it from a dealer so got my money back but after saving up for a while it was disheartening after wanting one for so long
Amateur Question : If the bearings are out of round, is the crankshaft not out of round also ? So will the new bearings not just start to wear excessively ?
Cranks are so bloody hard now I’d be surprised if the crank was worn considering the wear on the bearings. You normal get crank wear if the crank has worn completely through the bearing surface.
Think about the movement going on. Rod and journal comes down and deccelerates. Comes up and deccelerates. It is basically describing a very slightly oval arc. Ergo slightly oval bearings.
Job well done, guys! Gonna have to get my rod bearings swapped out on my car some day, which I’m kinda dreading, given how bloody dodgy the garages here in India are! 🙈
I bet more than a few E9X M3s experienced spun bearings and wrote the engine off from the BMW free maintenance program they came with that also included oil changes at 25'000km intervals! Yes they nearly take 9L of oil but such an extended interval was purely to save money on BMW's part. Most Blackstone oil analysis shows the oil being good for about 10'000km which is plenty for a sports car, which means if anyone followed the recommended and included services and intervals, they would be running their high strung engine on oil that is up to two and a half times past its laboratory verified usual lifespan.
This shows that S65 RB is a hoax. I live in Canada and bought a used E90M3 with next to no history and 100k miles. I then continued to drive it in winter. Many cold starts at -40*C. Finally did the job. Annnnnd guess what, they didn’t need to be done. This is a very reliable platform and owners/ many mechanics have blown this out of proportion.
Not sure I’d say it’s a hoax based on our experience of hundreds of cars. But it is very hard to truly tell the condition before removal as we showed in the video. The 60k car was incredibly close to failure in our opinion.
For someone looking to get an E92 M3 and also someone who likes watching a well made maintenance video. This was absolutely 💯 Amazing video please keep these coming!! Liked and subbed :)
I've been thinking of buying one of these... Usually I'm not worried about doing the work myself. Done everything on my current bmw... but damn it.. I dont have a hoist
Great to see this work in progress! Nice seeing Evolve bring some new life to car which by-and-large looks pretty well looked after! It would be interesting to a real time timer running during work done, or would that be too scary? Best not knowing sometimes 😬 Question... is it necessary to replace rod bearings on an N52? Or just the V8,s?
@@bouncycastles1214 1st mine was 14owners n 185k mileage.still not so bad no rust whatsoever.after 1month owning went limp mode,needed dpf delete 450£ + turbo recondition 1200£. later on crankshaft pulley was loose change that all belts,after alternator die change that,battery.last was abs pump changed thats from bigger repairs.a[part from that great car would buy again and maybe will,still looks cool not outdated much lol
Nice job!! I met Imran many years ago when Dyno dynamics used his Dyno as a demo for us, great guy. I don't suppose you guys have a spare S65 sump laying around do you? I have installed an S65, 6 speed box and LSD from a scrap M3 into my Mercedes 190e but the sump has a crack in it. I had it welded but the heat warped the sump and now it won't seal properly. Keep up the good work!!
How do the Main bearings hold up ?...would like to know how often the mains fail...and if they still fail after having the oe rod bearings replaced with BE ones
Can you please tell me about the project car with 6 previous owners that you mentioned in this video? I would like to watch videos of it if they are posted.
question.....Would a black stone analysis have showed any symptoms/precursors to cylinder 8's journey to fail? Like anything to suggest the extra wear?
Not convinced on a singular oil analysis on its own. Without knowing how long the oil had been in for and how the car had been driven during that time it’s quite hard to take any real advice from it. As an owner doing them regularly it could be a good indication.
Can I ask, why are the crank bearings called rod bearing??? I know theyre attached to the Conrod But I thought the rod bearings were the small end bearings at the piston end
@@EvolveAutomotive thank you for explaining I understand it now, it’s not what the crank runs on it’s what the rods run on,doh!! Don’t you check or do the main bearings as a matter of course after making that much effort
So why do we think they’ve survived so well vs other cars? Good warm up and warm down? Do you guys recommend the standard bmw recommended viscosity of oil? Edit: just noticed you’re using standard viscosity! Missed that at first! And excellent video 👍♥️
Most likely just looked after well, warmed up correctly. The cold start is the period of high wear, so it’s possible this car has done a lot of long journeys rather than short start stop type around town,
