Spark plug hit by piston, valve? M103 engine
Photo below of spark plug out of M103 engine. Something has hit the end of the plug don't know what. Must have been a valve or piston, but how?
I just put head back on after doing heat gasket. Apparently I screwed something up. Before removing head engine was set at TDC for Cylinder one and cam grear sprocket was put back on exactly as taken off. Chain was put on at same place on cam gear as it was removed
What could have caused my problem and what can I do to fix it?
