Well, Bus Driver, yours was a sensible answer to a no way dumb question. Probably most of the guys on here own older tractors without PCV so that little crankcase breather does bear to have some regular attention. There definitely is some movement of air both in and out of the crankcase/valve cover areas thru the crankcase breather.

Under extremely dusty conditions, service breather cap twice daily." Sounds to me like A-C takes this rather seriously! I can only conclude from some of the answers, the responders were thinking that only dirt entering the compression chamber is harmful and not considering that dirt in the crankcase/valve cover area can be a significant cause of wear as well. I"m sure at least some will take something good away from your post.
