How does a 130,000 mile M4 engine look inside? Evolve S55 Billet Crank Hub Fix

Matt bought his F82 M4 with 125,000 miles on, and has done 5000 trouble free miles (other than 2 oil top ups...) 


We were curious to see what the inside of the engine was looking like after that many miles, and having only been serviced to BMWs service intervals. Combine that with the small niggle of crank hub slip (although unlikely to ever happen with the plans for the car and how I drive) it seemed a good opportunity to upgrade the Crank Hub to the Evolve 4 pin billet hub. 


We show the entire process of the Crank Hub upgrade, along with a detailed explanation of the issue, why it happens and how we have fixed it.
