Those bearings aren't the worst, but the bottom line is that they were still worn. You've spent more time and effort changing other parts on it, so I hope you feel that it was well worth it. You have nothing to worry about now.

@trdric 3 года назад

I am a reliability engineer and oil analysis are always subjective if not done frequently. Engines are usually difficult to diagnosis with these because the oil is frequently changed. In your case maybe 3 years ago the copper content was higher but we can''t confirm. This is why having a trend of oil analysis is good but i understand thats it not cheap. In the manufacturing industries we will usually use it to confirm a problem seen by something else (vibration analysis usually). These types of bearing are not even picked up by vibration analysis anyway so the best way is always to inspect them visually. It is a labor intensive job but its cheaper than running them until they trash the engine. Good job looking it up ! Hoping the sc LS will be able to keep up :P Toyota biased here

@graphitedak04 3 года назад

I get a Blackstone oil analysis performed each oil change. However after seeing those S65 rod bearings bearings and the corresponding oil report I was having second thoughts about continuing to get them. Your comment gives me some piece of mind about still utilizing the analysis but focusing more on trends than a singular report.

From someone that started down this path a couple years ago, it’s great to see another M5 Touring build. When I did my rod bearings they looked fine but had already purchased all the bits so...I typically purchase everything from FCP but ECS offered WPC treated bearings. I spring for those. As for your hassle with the S62 on the engine stand, that’s too relatable! From trusting 4 bolts, rotating it and then things getting in the way. Great job and Paul is a great guy to help out as well. He’s helped me over the years.

@simontallboy209 3 года назад

I think oil tests are a good tool. I worked for a battery company. Our trucks were nearly always maxed out because ideally for every battery you sell you want to collect a core. The owner ran synthetic oil in the motor, transmission and axles and he had the oil analysis done. Those trucks are still going with the original power train. That impressed me. I own a Ram and some Hemi engines are having lifter and camshaft problems, so I'm doing the oil analysis to get an idea of how the motor is wearing. They are useful. I towed my trailer through the Rockies, and after 5000km got the oil tested. I then put on 5000km of short town driving and a little towing. Around town was alot harder on the oil and motor. Since the Ram is my daily I like getting a better idea in how the motor is doing. Also with the price of a replacement being so expensive I want this truck to last a while.

Great work guys! This episode is exacly why I sold my E39 M5. I loved it and enjoyed it but I'm simply done with BMW V8. I "downgraded" to S52 engine (I've put it in my E39 528 along with 5 speed manual). Yes, I've lost bunch of HP and torque but working on inline 6 is such a joy and it's fast enough for me. With just completed custom exhaust (the whole system) I'm at around 3500 lbs which makes my E39 500 lbs lighter than M5 and it has real steering, lol.

Mmm, I have fond memories of doing this to my E39 M5 in my garage back in the day. I bought it and the rod bearings were completely trashed so I did the job on my back on jack stands (not fun!). It turned out just fine and I had a great time with the M5 afterwards, those were the golden days.

@Kroberter 3 года назад

Perfect timing on the bearing repair. Any longer and a knock would develop eventually pumping shavings throughout the engine and the repairs would have been much more extensive. Most of the bearings I see (in the commercial diesel industry) once the soft metal/polymer layers disappear the bearings have a handful of hours at full load before everything comes apart.

@davej.6290 3 года назад

@tannerpowell6525 3 года назад

The words you need are babbitt and backer. The babbitt is the soft outer layers designed to absorb the occasional contact and protect the crank. The backer is usually made of steel, supports the babbitt, and spreads the load on the rod and block journals.

@frozenpete788 3 года назад

This is something I didn't do when I was a younger mechanic, but now, man I prefer spending (and not wasting I guarantee you) a few minutes chasing threads, cleaning, blowing with air, brake cleaner, brushing, triple checking, clean the bolts I'm reusing that are exposed to dirt etc, it makes you life much easier. And when you assemble everything back, you can make the difference between "it must be crap somewhere" vs "I'm sure I'm pulling the threads right now". About the bearings it's hard to tell, it's a matter of clearance, whether you race it or dialy it, long vs short trips, very cold start or not etc. Those bearings could have done more with good oil, relaxed driving and longer trips with nice oil temp I'd say. Of course in the long term it could have been worse and risking damaging the crank isn't worth it anyway
