my management light is on my vauxhall corsa 1.2 03 reg the car has slight miss on engine got it checked found out no compression in cylinder 4 could it be head gasket if not what can it be the spark plug is black
The exhaust camshaft has a habit of breaking on these engines at about 30k miles or so. I hope it isn't that, and that it is something more simple like the head gasket blown.
