Valve seal for burning oil/creating carbon possible that could be hangin up a valve.
It doesn't actually have anything to do in regards to a low compression cylinder, but it could effect the combustion chamber if it is poluting the system with oil.
I would be its more of valve SEATS or a cracked piston.
