what damage can a broken glow plug in a engine cause
Overvoltage damages/Broken heating coil. Overvoltage damage arises when the wrong glow plug (12 V instead of. 24 V) was installed. It is also possible that the control unit generates too much voltage or the current flow is switched off too late.on-tight pistons and valves can also be a cause for this, insofar as oil penetrates into the combustion chamber. Severe overheating can also break glow plugs. Non-tight pistons and valves can also be a cause for overheating damage, insofar as oil penetrates into the combustion chamber.
