Stats for valve adjustments

[Ncdan]

Hi guys, I'm trying to learn as much as possible about my 07 Calvin so I have a valve adjustment question. Is it common to check the valves of these motors and the spec not to be out enough to cause an issue. In the realistic world what's the most mileage that's acceptable between valve adjustment checks. Thanks in advance for responses.

It doesn't take long to check/set the valve lash.  Do it at the recommended intervals at first.  If the lash remains within spec. at each check, you can extend the time between later checks.
