They were original bearings on my 2004 MY. Currently @218K miles.

Here's a link to some pictures I took during my install: http://m3forum.net/m3forum/showthrea...+bearing+video

I agree if you want to go over he 80k to 100k range.

I'd rather just bite the bullet and do the rod bearings since I DIY. Might be worth doing some oil analysis if you can't or won't DIY.

Doing oil analysis at $30 a pop seems like kind of waste over the long run. 10 oil changes and you could have bought the bearings already.

Oil analysis lets you know about far more than just rob bearing replacement intervals. I can't imagine not doing it with every oil change.

So that thread mentions that you were doing it "second time around". At what mileage was the first time around done? Was it just 15k miles before?

Hard to believe that is the original set that lasted 200k miles from all the other cars I've seen. That must be some serious "granny" driving, might as well get a honda civic if you don't enjoy the s54 . Did previous owner replace them at some point?

These are originals. The first time I tried replacing bearings, I was only able to do one pair. I didn't drop the sub frame and didn't have the correct tools which caused me to strip the heads on most of the rod bolts. So one pair has 15k miles and the rest have 215k miles. I rarely redline it and mostly stay under 5k rpm.

I think that makes a huge difference in these motors. My theory is that running the motor to redline is a major contributor to bearing wear.

Default Re: Rod bearing pics - 2004 M3 motor w/93k miles

Hey guys,

I've recently been thinking about doing my rod bearings. My car currently sits at 183,000km (114,000 miles).

The previous owner thinks he at some point saw something in the service history that said the rod bearings were done under recall in its earlier years (2002 car) but can't be for certain. So I have no idea if it's ever been done.


I figure I might as well do an oil analysis and address any issues, including rod bearings, over the off season since track season is over.

But then I got to thinking.... I've had the car for about a year and did an oil change when I first got the car. Since then, I've only put about 3200km on the car (2000 miles). During this time though, I did encounter some oil leak issues (oil pan gasket) so I probably topped up 4 or 5 quartz over those 2000 miles. And when the car went into the dealer to fix the oil pan gasket, I believe they must have drained the oil and replaced with all new oil. And that was about 125 miles ago that it was in the shop.

So with all this oil work having been done in the last 2000 miles, if I did an oil change and sent it to Blackstone for an analysis right now, would that be completely useless as my oil is quite "new"?

Thanks guys!

The substances being measured accumulate in the oil over a period of usage...mileage in this case. Its hard to say but I would think that blackstone can help with that analysis. You're not using blackstone to run oil samples because you can get it done for less with more detail elsewhere. You want access to the analysis of the data which they should have a really good handle of.

I did an analysis of 1000 mile old oil and the made the analysis from the elevated copper reading that my rod bearings were about to go. By the time I received the report, I had spun my bearings at the track the day before.

Running the motor to failure at this point isn't a terrible idea. You can get a used motor for about $3500. As long as that used motor is good and you only throw rod bearings, VANOS rebuild, and a valve adjustment at it...you can part our your blown motor and maybe get to about the same financial point as just doing the rod bearings now assuming you DIY everything.

Hindsight is 20/20 but if you pull the oil pan its not a bad idea to do rod bearings.

The problem with that is that most motors seem to come with some sort of undocumented issue. Most people I know that swap motors have a significant issue again shortly thereafter. Sometimes the devil you know is better than the devil you don't.

Which is why I like to do oil analysis at every oil change. Spot a change in the trend-- address it before it's an issue. E.g. your lead levels would have elevated long before your copper levels did, had you been doing oil analysis all along-- then you would been out a couple hundred for a DIY rob bearing change instead of $3500 for an engine, plus all the lock downs again. And rod bearing wear is just one of many issues oil analysis can tell you about.

I would not count on blackstone's analysis of levels-- their knowledge is much more general instead of s54 specific.
