Found my compression issue

In diagnosing a bad running engine I ran a compression check. Cylinder #4 came up at 0 so I knew I had an issue. I used my bore scope and didn't see any cylinder wall or valve face issues. Pulled the head to find a broken valve seal. The valve seal allowed oil to run down the valve stem and cause buildup. The buildup prevented the valve from closing. Here is a quick peek inside my engine
