"NO THEY ALL WILL NOT FAIL SUB 100K MILES. Go on auto trader and search, you'll find ~500 cars for sale and over half of them are north of 100k miles. Then go on zoomthelist or allofcraigs and search, you'll find so many cars without any mention of "rod bearings".
Then go on nasioc and iwsti and search. Their bottom ends are way more problematic than ours, and guess what their forum is just so ******* paranoid. Yet I still have many friends with over 100k miles on an STI stock bottom end.
FORUMS ARE A BREADING GROUND FOR PARANOIA.
I've been on this forum for years and I'm almost through with it. This RB talk is really out of control and guess what, no one is going to want to own an E60 because of people on this forum saying things like "Its a ticking time bomb" "The tws is syrup, run 0w40" "Oh man the problem is BMW for not putting nascar standard clearance in a high revving motor" "oh man, look at those wear patters, they look bad, i see copper! were all doomed!!!!!!"
Ive seen so many "bad" bearings bearings (replaced as PM) posted with what I see as normal wear patterns and no clearance measurements. The numbers are what matters, not judging a book by its cover. Hell, I saw a well respected user of the forums pulled a set of bearings out of a 15k motor that he rebuilt as a control and ran on a lighter oil, the bearings looked the same as 99% of the other pulled as PM. He then had the gall to say "those bearings would have never made it to 30k".
Spend some time on the E39 forum, a great deal of those users feel their cars have RB problems and guess what, that paranoia has settled down now that their cars are aging. Its very common to see an E39 with north of 150K miles now so no one worries anymore.
Every time I run into someone with an S85 car I chat. I talked to a guy with an IB 06 the other week and he had 120k. He had no clue that his motor "is a ticking time bomb" because he isnt on this forum. Guess what, he enjoys his car and tracks it.
This RB trend needs to stop before the E60 goes the way of the 996. There's a reason why that amazing generation has no resale value even though the failure rate wasn't that high. The problem was TALKED TO DEATH by enthusiasts. The failure rates on RB on these cars are nothing if you consider how many S85s are out there. Like 20k!!! Yet everyone who joins this forums posts something out of regret because now they're scared to own the car. Think about the people who browse without signing in! They're never going to buy one! Over the past two years I've seen the resale value of the E63 and E60 TANK. ANYONE WANT TO TAKE A GUESS WHY????
STOP, JUST STOP with the RB PARANOIA.
Feel free to find my thread I made not too long ago where I had dozens of s85 users comment their milage on a stock bottom end.
Buy an E60
ALWAYS USE 91 OR HIGHER OCTANE.
ALWAYS LET IT WARM UP BEFORE BEATING.
NEVER TRACK THE CAR ON "MINIMUM OIL LEVEL"
NEVER REDLINE IT AT IDLE TO HEAR THE SOUND
NEVER REDLINE IT WHEN COLD
ALWAYS USE APPROVED OIL and not whatever crap the conspiracy theorists suggest.
DONT REFLASH YOUR ECU WITH ONE OF THE MANY REVERSE ENGINEERED "TUNES" AVAILABLE.
Do this and the car will last a long time."

Get off your soap box. I've been in the car industry for 20 years and most people especially the original owners of E60 & E90/92 M3s will never rev their engines anywhere close to redline. You think most of those original owners are going out and auto cross or tracking their cars. I'll bet only a fraction of original owners can push their car 10/10th.
My point is most of these cars that are now on the used car market have never been driven hard. I'm sure some have. Are you kidding me of your supposed 20K S85 how many you think have been driven hard. Doing a quick blast down the highway is not driving a car hard.
As for the 996 it did have a problem. The IMS and if you didn't fix it and you drove the car hard the engine would fail.
