Z4M Crank Rod Bearing Shells

Guys

As promised please see pictures taken by James during the service and bearings change. He has mentioned that the car is in great condition otherwise which is reassuring.

Oh that's interesting.
They removed the entire subframe and have modified an old subframe to support the engine just from the side.
Quite a different approach from the BMW prescribed special tools.

Thanks for posting the photos mate, but those images are quite concerning with the shells down to the copper at just 26,000 miles?!

Just goes to show that you never really know with these engines and that doing the rod bearing service is worth it from a peace of mind perspective.

Happy M motoring :thumbsup:
