High mileage 08s report in!

[GotV8?]

I'm about to hit 90k on original Rod Bearings, hoping to do preventative once I get my BE bearings soon with BE ARP bolts. Been waiting since December of 2019. Cant wait to post in the future once I hit 100k

[Kiefermeister]

Just dropped off my 08 with 156k miles on original bearings at ACM for first rod bearing service. PO had extensive lab records, extremely well maintained and the car still runs silky smooth but I guess it's probably overdue. I'll post pics if ACM send them to me but I'm sure they'll post up on their thread!

Make sure to have them replace your motor mounts while they're in there. It shouldn't cost any extra labor.

Look forward to RB pics

They gave me the old bearings. Some seem to be down to copper but I've seen worse with less miles. I'd say not too bad for 156k miles but definitely worn and glad I got it done!

Nice! yeah mine was about the same.

Feels so good not having to worry about it for another 100k miles

You definitely got one of the good ones!

Which does not stop the RB issue, it'll delay it at best.

Have you posted that photo to the rod bearing condition thread?
Anyway, for 156k that's not terrible, but with the copper showing, that is into the danger zone, changed just in time!

[slowe90m3]

2008 e90 103k miles and driven hard, 3 accidents, and still runs like a champ. Original coils, bearings, and actuators. Who wants to buy it? Hah.

[Mpow-wow]

106k original RB's, actuators done, nothing else major.

So it's your belief that every s65 will die of rod bearing failure eventually?

Every machine has it's weak points. Everything will require maintenance or replacement.

I'm at 211000 miles. Rod bearings at 147k. My old bearings look just like 99 percent of those we see. Worn but not ready to fail.

I think 75% of the visible wear occurs during the first 6000 miles break in. I got my car with 54k on it. I did oil analysis always until after i did the bearings at 147k. All the metal or lead or whatever happened prior to 54k. Or Blackstone failed to detect metals 54-147k.

100013 miles 2008 M3 E92 Interlagos Blue 6MT. Bought the car couple months ago. Doing rod bearings this month.

[slowdown_dan]

It just gets me the number of times people are like "just changed my bearings, mechanic said I caught it just in time!"

looool k.

Were they going to go eventually, some day? Maybe. Was the mechanic trying to make you feel good about the coin you just dropped with him? 100%.

You can put money on one thing you won't hear a mechanic tell you: "yea man I think these bearings were fine, probably didn't have to just pay me 2500 bucks"

Waiting patiently for someone to make the comment about needing to accept that spending 2500 bucks on bearings when you own a BMW is just a C.O.B.

It’s a peace of mind thing. In concept it’s not much different than doing other preventative maintenance, though I don’t know of any car where RBs are considered maintenance, lol. Has the internet blown it out of proportion? Probably. If you have the means and it makes you feel better, do it, but there’s no right answer.

And maintenance with BMWs, especially M cars, is a pay to play thing.

67500 miles on my 08 E93 6MT I bought 2 weeks ago. Just did oil service. Its my weekend car but planning on doing RB once its around 70k

[dfjaws]

I bought mine at 44k miles. Now I’m up to 117k. Original rod bearings. I’ve replaced throttle actuators, drive shaft, idler pulley, radiator, water pump (preventative), thermostat (preventative) and various cooling hoses (preventative). Maintenance has included the usual oil, spark plugs, brakes, etc. It’ll be 7 years in October and I still love this car like it’s day one.

At 117.5k on my '08, just did bearings (#7 was almost entirely copper, looked pretty bad and was scored), dct pan is definitely leaking so that's on my to-do in the next month or so, along with a new driveshaft and valve covers as they're both not doing very good. All things considered, for ~120k, about 7k in "non consumable" items seems fair for a performance car. I'm still very happy and love driving it daily.

[tjsabec]

I just traded my 08 E90 @ 89k miles. I bought it @ 20k miles CPO 10 years ago. I replaced the serpentine belt and had to do a Time-CERT on the front oil plug. That was it, original rod bearings (did oil analysis every change) The pre-cat O2 sensors needed replaced, was throwing intermittent codes, but I traded it before I got around to changing them.

I had Akapovic full race exhaust and stage 2 BPM Sport Tune.


Traded on a new 2020 M2C. I love the M2, but miss the sound of my S65.

I’m very interested in S65 longevity, assuming RBs have been done. Do you notice higher oil consumption or loss of power/compression at such higher mileages? Any recent dyno tests?

I dyno'ed my car at 100K
she showed about the same power output as 20K miles car with similar mods, so I'm super happy with the performance

on oil consumption: I'm adding 0.5-0.75qt per 5000 miles, which I guess completely normal
