3208 - Valve Lash Adjustment

[orbitalsolutions]

How often do you folks perform a valve lash adjustment?

I know that Cat's official reccomendation is with every oil change.

This I feel certain, is overkill. My bus had a factory rebuilt 3208
installed about 3 years ago. There is about 13 thousand miles on it.

The motor runs perfect, nice and smooth. To my knowledge there has
never been a valve adjustment performed.

Should I pull the covers and get out the feeler guage?

Thanks in advance for your input.
