American Dave' Rod Bearing Replacement

American Dave · 10-20-2015, 12:47 AM

So my 2008 M3 was a one owner I bought 12 months ago with 69K kms on the clock. In the last 12 months I did one speed event and track day. I changed the oil 10w-60 a total of 4 times over that period and most recently had the oil analysed. Minute traces of copper and lead showed up but nothing to worry about I was told. The car had never missed a beat or shown any signs, noises of bearing issues. Still with no warranty and not wanting to spend big money on a new engine I decided to invest in some preventative maintenance. I went with the VAC coated bearings because I did not want to wait any longer. I chose to use my local mechanic Galvsport do all the work as they had experience doing this job. They pulled the all the bearings and they showed consistent wear, with a couple of them showing wear thru to the copper. Well worth doing I think. My cost was $2600 parts and labour. The car was back on the road after a couple of days and is running fine. Peace of mind was worth $2600 for me.

Not a bearing expert. Just have seen a lot worse on here. I was expecting to see a lot more brown coming from an 08.

More like this?

Also an '08 at about 65k miles. Didn't fare too well.

While that may be true, the fact of the matter is that bearing aren't a wear item and should exhibit little to no wear. The fact that his wore down to the copper indicates that his bearing weren't faring well at all.
