Comprehensive S85 Rod Bearing Picture Thread

With all the discussion of late on the subject of rod bearings, I thought it would be a good idea to have a single thread to collect pictures of rod bearings which have been preventively changed. I say preventative because if there has been an engine failure, there are several possible reasons that can't be isolated as easily as in a currently running engine.

Edit: An excellent discussion on M3Post about the S65/S85 Rod Bearings and their measurements. Well worth the read as the most well documented and concise discussion about the hypothesized source of the problem and potential solutions.

As people add their pictures below, please include:
- mileage
- owner history
- average oil change interval
- oil analysis reports if available
- reason you decided to change (fear, suspect noise, suspect oil analysis, hard usage, etc)
- DIY or shop changed
- link to your change thread I you have one

Hopefully over time we will drag up some preventative changes that don't show significant wear, but as of starting this thread, I have yet to see a set of bearings that look "great".

Mileage
95,600

Owner history
I'm second owner since 52,000miles till now - 95,600miles
- Daily Driver, 6 times a year track days
- I do not push the car until reaching temperatures of 180-210 F. Once warmed a one ramp is never wasted, and driven like Sabina's little brother.
- I have reach over 190mph serveral times
- 91 premium fuel
- Model 2007/09
- after bearing change running Mobile 1 0W-40

Average oil change interval
5-6000 miles from 52,000 to 94,000 running Liqui Moly 10W-60

Why
Based on rod bearing issues on the S85 & S65, at my mileage it was a preventive decision.

How
In my garage

BACKGROUND:

- mileage: currently 86,xxx miles and replaced at 84,xxx miles
- owner history: owner since 28,xxx miles, purchased with full dealer records from private individual
- average oil change interval: between 3,000 to 4,000-ish miles
- oil analysis reports if available
- reason you decided to change (fear, suspect noise, suspect oil analysis, hard usage, etc): All the above, except noise.
- DIY or shop changed: Indy Shop, OMS in Oceanside, CA oceansidemotorsports.com
- Rod bearings at 84,000 miles

DETAILS:

84,000 miles replaced, with the last 60,000ish miles under my ownership. Oil change intervals of 3,000 to 4,000 miles with Motul 7100 10w60. My car is my long distance commuter, from SoCal to San Francisco, Vegas, Phoenix, Tucson, and points in between. I also track her on a regular basis, and she is not afraid of the redline. Daily shift points for me are at 6000 rpm, unless she's cold or I need to be quiet.

My e60 is three of three m5s in my current garage. I'm meticulous about proper warm up and cool down with ///M engines. Much like WallyM5, I drive all my m5s hard, but never put them away dirty -- mechanically speaking. Consumables get replaced well ahead of schedule like bushings, fluids, and now rod bearings.

Attached is my Blackstone, I'll add my rod bearing pictures later today when I can get on my computer. The pictures of my rod bearings can also be found on my original thread as well.

EDIT: Oil consumption after 2,800 miles: ZERO. Zero, even after an 800 mile trip to NorCal. The top is the the top and bottom is the bottom.

-Bought at 40K now has 50K.

-03/2008 build.

-I have done 2 oil changes prior to bearing change.

-Last 5K was LM oil.

-Always Shell 93 octane.

-Not a daily driver.

-Not tracked.

-No tunes or mod exhaust. Totally stock.

-I had no symptoms, zero. Since I didn't know the first 40K history and started to "smell" rod bearing problems on the forum, I decided to do a reset. Now I know what I have. Both BS reports were excellent with no alarm bells as the car runs perfectly. 8 parts pb at the highest on BS report. I also wanted the forum to see what 50K bearings look like so others may make an informed decision. A spun rod bearing IMO is intolerable and wanted to minimize the chance of having one. There are however, no guarantees.

-Did it myself on a lift.

-Breaking in on Rotella T6 for 1K then switching to M1 0W40.

-Also replaced vanos high pressure hose while the pan was off.


Top picture is the upper shells. I only have 8 sets in the picture I took but the other sets of shells look the same.

Heres my rod bearings as promised. My car has 58k at the moment and its an SMG, i decided to change them out as a preventative measure. Im third owner and cannot testify as to the previous two owners driving habits. I change my oil and filter every 7000 or so miles, my car had 35k on the clock when i aquired it, so ive changed the oil three times so far. I also changed the VANOS solenoids along with the RB, not sure how long my solenoids were out of spec but they were only slightly out of spec when i checked them (.54, .52, .54, .52). I dont track my car but i do go for the occasional spirited drive with other forum members. I always allowed my car proper time to warm up before any high R pulls. I use castrol 10-60 and OEM filters. My car is an RPI S2 (and catless if it makes a difference). The job ran me roughly 2k total (rod bearings only). Car was running just fine prior to the RB swap, havent noticed any difference in performance as im still breaking them in. Comprehensive S85 Rod Bearing Picture Thread-090313205940.jpg
