As my car trotted over 100k I'd always pondered swapping the bearings out. The guy I regularly take my car to can be a bit funny about certain things and he told me that it wasn't really something I should worry about. But obviously reading all the bad stories got me worried as I'm hoping to hold on to the car and not sell it.
So at 116,000 and due for an oil change I booked my 2006 M Roadster in for rod bearings, oil change, valve adjustment, and vanos exhaust hub upgrade.
I just got the car back this morning after dropping it off on Monday and for one am very glad I decided to upgrade the vanos part, as one of the tabs had snapped off on my OEM original piece. Its probably some sort of a miracle it never took out the timing chain. I religiously warm the car up properly before giving it the message but I must say I drive the car as intended when conditions allow.
I'm hoping the photos of my bearings attach okay. I've been doing oil analysis reports since 70k and they never really picked up any copper in the oil. I bought the car on 42k so perhaps this wear could have occurred before my ownership? I somehow doubt it.
I went with the WPC treated OEM bearings which should hopefully see me good for another 100k at least. I figured if these are better that the OEM ones they should last longer. But I admit I don't know too much behind the science.
Upper bearings are on the right, lower bearings on the left. And a close up of the worst one.
