When was the last time the valves were adjusted?

Someone here on this forum mentioned how an old German mechanic taught him how to do a valve adjustment. Since using this technique, I have had very little rattling.

The "technique": Lube the feeler guage with oil and ensure there is absolutly no drag on the guage while checking. After making adjustments drive it for at least 100 miles and let it set overnight. Recheck clearances with the lube oil and feeler guage. It takes longer but is worth it.

I was surprised how much difference this made in smoothness! Bare minimum of shaking on cold start up and smooth when warm.
