you can normally also diagnose valve seals or guides looking at vacuum gauge. it vibrates alot at idle, and steadies out as you slowly increase RPMs.Oil smoke that shows up on warm start and after idling a while is typically valve seals. (or engine braking downhill) But if you don't notice noticeable consumption between changes, it's not enough to even bother fixing.
