Has anyone changed the PCV valve on their HCH I ? I have 97,000 km on mine right now and I would guess that it is time for a replacement. The owners manual does not seem to mention it. The shop manual states how to replace it but does not give a recommended mileage. Any thoughts??

Having owned many honda's, my experience has been that when the PCV finally sticks shut or open from sludge build-up, you will notice a distinctive odor eminating from under the hood, like unburned fuel or hot oil, choking exhaust fumes, etc. Then it's definitely time to change it. It's a very cheap part so you could even replace it every 20K for example, just to avoid the stink. Many dealers used to replace it, needlessly, at each oil change, but probably not any more.

Thanks ralph_dog. I to have replaced them on all of my other cars but it was written as a maintenance item in the owners manuals of those cars. It appears from the shop manual of the HCH I that you have to take off the intake manifold in order to make the change. This is definitely not something you would do every 20,000 kilometers or so. Anyone else with experience on this topic?
