96 odyssey. I hear a high pitch squeal sounds like under the valve cover. Best heard at idle. Sometimes quiet. Sometimes quite loud. Sometimes subtle. It will pass through all of those while idling in park. It seems to go away at higher rpm. Im pretty sure my seals under the rocker assembly are bad; there’s oil in the plug holes. Plan to replace. 293K miles.
