Valve seat and or head
After doing a port n polish job on my RENIX head, there is a crack in the exhaust valve seat in #2. What are the chances that the head is cracked as well?
Engine ran fine befor head was removed. No smokeing, noise or overheating at all prior to head removal...

How did you manage to crack it? And if it ran fine before than just replace that valve.

It was cracked prior to me removing it....No clue how. No pix, the crack wouldnt show up in the pic. It is inbetween the valves on the exhaust side of the cyl. up against the intake side of the exhaust valve seat..
