Anyone do Rod Bearings twice

I have an 08 with 112k miles. BMW did the rod bearings at 18k and actually replaced the crankshaft all under warranty. Should I do these again. Are they considered a wearable item or once you have new ones in you are good? I dont know if they are copper or aluminum but my next step was to do I a Blackstone oil analysis. I assume when BMW did them they used the same factory ones that caused the issue to begin with.

If you have OEM ones they should be replaced every 100,000 km maximum because of the tight clearances. Wether you have aluminum or copper ones depends on the year. Since yours is on 08 you have the copper ones which is good because you can do an oil test and if your bearings are wearing bad you can spot it. Next time you change them I would recommend BE or ACL or VAC you will find 90% of people on this forum use BE.

What ??!! BMW payed to replace your bearings and crankshaft under warranty ? I have never heard that in 8 years on this forum. The last thing BMW want is to officially admit their engine design issue. Please elaborate on the circumstances ? How did they even accept to open up the engine ?
The default bs attitude i received from BMW all during my factory warranty years was "nothing is never wrong with the car unless the computer tells us so, or if something is visibly broken and we won't open it up unless there is a code". Even when my AC wasn't cooling well, i had to complain three times before they eventually replaced a faulty evaporator and i had to go to several BMW dealers including the one who sold me the car new.

In all engines, rod bearings are wear and tear parts. They just happen to be more fragile in S65 engines, and the change intervals aren't as long as some engines. I plan to do mine every 80k kms.

There is a member on here that received a new engine from BMW as a "good will" gesture for the bearing issue. If I recall correctly, member was barely out of warranty when bearings spun. After some back and forth, BMW decided to swap engine for this member.

Sorry, don't remember who it is. But this was a while back. Haven't heard BMW doing anything like that ever again.

Did my first RB's at EAS. Had my dealer do them 1000,000 later again due to something that hit my oil pan. The first set of replacements looked great with 100,000 give or take on them when BMW gave them back to me. I would consider these a 100,000 service for piece of mind but I think I could extend to 150,000 safely.

Sure, they actually did that for quite a few original owners, especially those who knew how to maneuver BMW's concern for bad publicity. Some admitted the engine replacement was conditional to a non-public disclosure of the terms of the resolution to which the owners obviously agreed (gagging).

But this poster is talking about sth entirely different : preventive (?) RB + crankshaft replacement at 18K COVERED under warranty (!!!). My guess is this is not exactly what happened.

Was the first replacement with OEM bearings? Also, how did the 1st set(the original) of bearings look?
