Valve adjustment on K-series motors: What's different?
After doing a search, I'm still looking for more in-depth answers. My next stop will be clubrsx.com and I'll share it with AZ if I get any info.
For those who have adjusted their own valves on the K-series head, what specifically is different from using the good ol' feeler gage method? Is the method / accessibility of cranking the motor through the driver fender the same? Will we need to replace more than just the valve cover gasket (i.e. - seals surrounding spark plugs)?
I was able to stumble upon kurt bradley's overview on the valves, but still left me with questions.

Thanks for the help.

Your valves should not be noisy at this mileage. If you want to make yourself feel better, you can have a tech at the dealer stick his head under your hood. K-series engines do not have the heads and the valves torqued down the same way as traditional Honda engines as they are degree torqued instead. This is a little different than just torquing them down to a certain gap.

I didn't realize that either. Sounds like one would need a new measuring device to replace the feeler gauge. I haven't checked my manual, but I was under the impression these cars typically didn't valve adjustment until roughly 100k (which is a far cry from what Honda used to recommend on their older engines).

The valve adjustment is exactly like all other Hondas according to the service manual. Use feeler gauge to check clearance and tighten lock nut to 14 lbs. You don't necessarily have to use a torque wrench. The spec is merely for reference. Most people just hand tight the nuts.

The "adjust only if noisy" recommendation is a poor one, as valves that are tighter than spec will not generate noise. Only loose valves generate noise, I believe. IMO, I'd adjust them at least every 100K.
