An old test I use is to get the engine warm at operating temperature. Drive along say 50MPH and then lift your foot compeletely off the gas pedal for say 8-15 seconds then accelerate again. If you see blue smoke it is the valve guides/ valve stem seals.

My experience is if it is the rings, it does it all the time.
