Having problems with your 2000 BMW 5 Series ?
2001 525 oil getting in to number 2 cylinder - 2000 BMW 5 Series
Most likely to be a bad valve seal or cracked/worn oil ring though there could be other causes. The valve seal would be easier and much less expensive to replace, could even be considered a Do It Yourself project if you have mechanical experience/skills and tools. The Oil Ring would be a shop job as the engine will need to come out of the car.
Valve guide/seal, Piston rings, head gasket. Getting oil fouling on plug?
