What would piston 3 scorching on crown (just above first compression ring) mean to you guys? The engine is a 1.6cvh turbo i suspect it has a leaking head gasket and maybe even a leaking cylinder head. It overheated on the last day it was driven before the engine was opened up. It has Accralite 81mm pistons and steel rods it finished run in maybe 2000km ago, was running 14psi of boost. Any help would be greatly appreciated as i am thinking a lot of things could it be improper bore to piston clearance? please help

 

anyone?
