However our Asia hq refuse to do the preventive check under warranty claim for me hence I volunteered to pay. Any issues, they will step in to honour the warranty. So I'm basically taking a chance since Asia hq claims that they have not encountered or received any bearings issues claims.

Sorry to hear about your engine failure.

Curious to know! Do share once you hear back. Thanks everyone for their comments...including the hilariously butt hurt trolls (Bimmer Barney)

One oil analysis isn't going to tell you much, unless you're nearing failure. They're more effective in telling you how your internals are wearing.

How would he know if there's improvement after install? That post doesn't even make sense. Hey OP, did you see the comment about throttle actuators too? You should probably start a new thread asking for an explanation there too. Just make sure you do it before you

I think everyone agrees this thread has been thoroughly

and should be shut down. Moderators please close this thread.

It looks like you only drive a 335i....not sure how much your opinion holds in a forum for M's. Next you'll probably tell me you've chipped it and it has more hp and tq than E9XM's. All I can say is just keep on saving up for that M car buddy...

Well that was a meaningful post full of useful content for the community.

Everyone agrees that your thread is a waste. Hope you figure out the answer before you blow the engine and who knows what might happen to your throttle bodies!?

I won't say I "chipped it" because I don't drive a late 90's Camaro. I did Tune it and yes it does have more HP and TQ than a stock E9x M3 but most M3 owners don't speak about their cars in terms of those measurements, but rather about balance and lap times.

If anything my opinion should count more because I drive an N54; the most unreliable modern BMW engine. I know all about engine problems from Bavaria.

loveskiing · 07-28-2016, 10:06 PM

Wow, I'm so glad someone finally decided to talk about rod bearings. I too have a M3 and have recently begun to change them with every oil change prophylactically. I've found I'm saving $$$ with not having to send in Blackstone reports...not to mention all the incessant worry about when they'll blow up on me.
Now where can I go to talk about DCT vs MT?

masschaoz · 08-11-2016, 09:47 AM

I just gotten the results of my rod bearings..mileage 82k km. approx 50k miles

https://drive.google.com/file/d/0B6P...ew?usp=sharing

its in a word doc. Probably some of you could help advise if this is normal?

the techs have assessed this to be normal.

MasterP · 08-11-2016, 09:57 AM

In 2014 my 2008 S65 failed. Warranty company gave me a late 2011 Engine with 40K miles as it's replacement.

I had Bimmerworld bearings put in the warranty engine as a precaution. The 40K 2011 S65 also showed bearing wear.

Have a look at this article from Mahle-Clevite, and see the example photos of "normal wear" and "oil starvation": https://drive.google.com/file/d/0B6P...dMUkxCeTA/view

Most of your bearings look pretty normal, maybe 7&8 show a little starvation...but yours look better than many that have been taken apart.

Looks great! Not sure I would've replaced those

Latest issue.. BMW agreed to replace with new bearings.. However now after they fixed back the new bearings, the measurements of the bearing clearances are out of spec. Something very unusual so they have submitted a puma report.. The regional technical manager is gonna inspect my engine personally

pbonsalb · 09-19-2016, 04:43 PM

Find out for us the clearances that bmw considers to be out of spec.

0.07mm is what the technical manager claims for max clearance . My new bearings were measured at 0.076mm for 3 cylinders and the rest of the 5 cylinders were of a different clearance measurement , which in his definition would be considered out of spec.

My original bearings were measured at 0.063mm

Doc Oc · 09-21-2016, 12:45 PM

. 063 is pretty loose for oem, they're typically in the 035 to 039 range. 076 is too loose and may not maintain the wedge properly. By comparison the VAC's that came out of my engine measured about .05

Exactly.. It's either they measured wrongly or my engine specs are way off.. Could you imagine the regional technical manager quoting 0.07mm as the standard spec. Robert Bertuleit is his name.. I need to get some direct contact to feedback about this guy.

I would love to know if people are just changing the rod bearings at about 60K miles even with no problems.

Yes, many people are doing this as preventative maintenance. in fact, most of the RB replacements are as preventative.

A handful of people have decided to do this, yes.

Dr Q · 10-30-2016, 08:49 PM

I think I'll just that. Have 35k now. 2009.

Redd · 10-30-2016, 09:02 PM

Just changed the rod bearings in my 2010 E92 M3 (end 09 manufacture) at 90k kms and not a moment too soon. One of the shells was down to the copper already.

With the S65, I'm taking the mindset of not IF the bearings will fail, but WHEN they will fail. Just assume it's a wear and tear part and get them swapped out. I plan to do mine every 80k kms as the last set of bearings barely made it to 90k.
