I repeat my post because BMW without my permission it covers the pictures I show what they did wrong in this engine. A tragic story with a happy ending... Sometimes even an almost new car can cause an unpleasant surprise In this case, an inexperienced and short-sighted BMW mechanic was at fault. The car’s serpentine belt was damaged (it happens). Unfortunately, it was damaged so badly that it wound up on the crankshaft between the engine block and pulley, and pushed the crankshaft seal inside to the engine crankcase . The mechanic who repaired this , did not realize that a piece of belt got stuck inside the engine. It was there for several months, wound on one of the timing gears . Due to pressure , high temperatures, oil and high speed the belt fragment shredded into small pieces, which in turn clogged the oil pump. While driving, the engine lost oil pressure, the chain tensioner loosened tension and the chain start vibrated, damaged the guide elements and jumped a seven teeth. This was a worst case scenario for the owner of this car But I managed to fix it Will the owner report to the dealer for a refund? I don’t know, but he should . The possibility of pressing easy the crankshaft seal into the engine is a serious fault with this engine, which can be easily eliminated using a seal with a flange bmw could thank me for the information See more
