I have had so many coils burn out on bloody m50's. There could be an underlying cause I don't know about which I would love to hear about. But for now... I say m50 coil's should all be upgraded

M52 coils have different mounting locations, I have a set of perfect M50 coils in the FS section for £35 posted

Because oil is leaking past the cam cover gasket
