Hi jason carson,
It is not sticky valves that cused your problem. Replacing the valve seals would have solved your problem.
Valve seals harden over time and when it happens, oil is being burnt when engine is running but it does not come out in volume.
When engine is not running, oil leaks through the seals and stays in the inlet manifold or combustion chamber depending on the valve position.
If valves had stuck, the engine would not have run well.
