Lapping H22 valves ?
I have my cylinder head off because of low compression .
When I shine a light on the cylinder side of the valve and look into the exhaust I can see light through the tiny crack around the valve.
I can tell that the seats on the cylinder head are worn. But I bought new valves and I still have the small crack.
My question is should I regrind the seats or can I get away with just lapping it with the lapping compound?

Re: Lapping H22 valves ?
