In this Vlog, we run through BMW S55 Crank shaft slip issues and fixes

'The S55, BMWs mighty three litre straight six twin-turbocharged engine, as fitted to the M2 competition, M3 and M4 models is a fantastic power plant, with huge tuning potential, it does however have one major ‘flaw’ in its design, and that is the crankshaft hub/camshaft chain drive interface, which has unfortunately become a very common failure point when tuning, and the issue can even affect vehicles with a stock engine, albeit rarely'
