Engine oil leak on 2013 BMW 335i (cylinder#1 deformation?)
I put my car in the BWM service center and they said there is 22% engine oil
leakage, which they are suspecting there is a deformation of cylinder #1 in the
engine (not from anything else). Have anyone ever experienced such defects?
I am just stunned that deformation of the cylinder can actually happen when the
vehicle has not been involved in an accident
