Unless it's a 911 turbo...

With every oil change.

This sounds like an appealing option. Who'd you go with and did you purchase before or after the expiration of the factory warranty? Thanks.

@ OP: When the rod bearings are kaputt they'll be replaced.

The rb topic is such an overhyped under-delivering "issue" that it must be eligible for a "fake news" label. How many forum member owners have incurred catastrophic loss due to rb's? More than 0.001% ?

On a forum membership basis the stats are above 1% last I checked. Not everyone comes to the forums obviously, but it's on the order of magnitude of 1% failure rate

That's what I seem to recall when I was doing my research on whether or not to buy an extended warranty based on bearing failure alone.

I wonder what the % is for Supercharged engines?

[Redd]

Not many may have experienced actual rod bearing failure, but 70% of the people I know who preemptively replaced their bearings - myself included - all saw advanced bearing wear. My own experience, all of my bearings showed wear on the babbit layer, and one was worn down to copper. Mileage during change was 90k kms, end 2009 manufacture.

So yeah, I'd definitely recommend changing your rod bearings every 80k kms.

A reputable shop that does RB changes, says out of 10 S65 cars they've done, only 2 didn't need them changed, 8 showed excessive wear. That is a lot higher than 1% in that small group. I believe there a lot of S65 cars driving around out there that need RB but have good UOA and don't knock. This is one of those things, waiting until it makes noise, well, it's too late at that point.

I think it's odd that folks talk smack about BMW saying "lifetime" fluids, but don't want to accept preventive rod bearing changes. I for one would much rather leave transmission fluid alone, than opting out on changing the rod bearings. I challenge anyone one that thinks they don't require preventive maintenance to show me one race motor that goes 80k miles before teardown.

You tell me this is something you'd do to your OWN personal car. I know I wouldn't.

While the PDK is a very solid unit, they're not 100% bulletproof either. New gearbox probably costs more than my E36 M3 too

if I broke my PDK tracking my 911 TT, I would pay you to dispose it in Mexico and split insurance payout, cuz that would be cheaper....

correction, that PDK probably costs as much as your Z4M at the minimum, if you don't have a core exchange, might cost as much as your E92...

[nycplumber]

Pdk breaking? Better chance of you cracking an 8 ball in pool.

I looked at it as PM, cost was on the order of a brake job at a shop. I would rather pay a little now rather than pay 4X to 5X more if there was an issue later.

How much did it cost you? I heard upwards of $3k for bearings.. that's a lot more than brakes lol

Price out front and rear brakes from a shop, you will be surprised.

Parts alone are over $1300.

https://www.ecstuning.com/b-assemble...4212283803kt2/.

Most shops would charge more for the parts.

I was quoted over $2k for the job at two different shops. (Dug up one estimate at $2100)

For the bearing job it was about $3K but I had motor mounts replaced along with Bimmerworld dip stick and power steering reservoir. EAS in California advertises the complete service for $2400.

Rod bearing change is a full day of labor and roughly $500 to $1000 in parts depending on what you use. Most shops charge book time and do it faster to make more.

Just my opinion regarding about rod bearings,

I have a 09 model running very healthy with absolutely no oil consumptions.
All I have done to my car is a regular BMW maintenance and driving hard.
I am might be in wrong group here but,
There are many e9x M3 owners with no bearing issues also.

Wishing that many of people like me can post here also
that way maybe it can contribute to solve this rod bearing riddle.

You don't know if you have rod bearing issues until you check. I used to post that I am on original rod bearings proudly with 147K miles with no noticeable issues. I changed them and they were worn to the copper (3 layers worn through).

wow I see, I have a buddy who did my brakes front only and charged $900

$250 each for rotors, $100 for pads and sensor. $600 total. That leaves $300 for your buddy's 2 hours of labor. I'd work for $150 per hour.

[BLuRRYM3]

I replaced mine at 60k. But I would pay attention to the copper levels on your Blackstone Labs report.
