Hi Gil! I want to thank you for taking the time to take my question, my daily driver is a 2014 M5 competition and I have racked up over 70,000 miles on it, my question is: does it need walnut blasting done? I’ve seen tons of pictures of other directed injected turbo BMWs that needed it bad but can really find any for the turbo V8s S63 or even N63. Also when would you recommend the rod bearings being replaced? I’ve seen where the S65 and S85 had problems with rod bearings.
Thank you so much for your time,
