The number 1 cylinder on my Z1 turbo started fouling a plug. Thought it was the head gasket. Pulled the head and found the intake side ring landing had broke off. No damage to the sleeve or the exhaust impeller on the turbo fortunately. Doesn't look like it melted from detonation, done that twice before and both times it was the two center cylinders on the exhaust side. Nobody makes a 1015 turbo kit anymore. Hate to re sleeve and go to a 1075. Doesn't seem like I have any choice. Anybody happen to have a 1015 turbo piston / ring set laying around?
