Pardon my ignorance, I know how easy it is to adjust a traditional engine's valves, but what bout the DOHC?I have what would seem to be a valve tick, in the past I would pull the valve cover, pinpoint the noise and tighten the rocker ever so slightly. With trial and error I'd get it to stop, and I would subsequently see performance and economy increase.
Any guidance is appreciated, I've had no luck with lurking, searching.
