ok i hear a tick.. i have pin pointed it to near the runner on the intake manifold adjacent to cylinder 1... valve?
valves? octane? valve ping? no way.valves...

Idk but i've never heard my injectors, all I hear is the rest of the motor running (mainly the exhaust)..valves? octane? valve ping? no way.
anyways, check valve adjustment like everyone else said. its a east check and you dont risk messing anything up judt checking it. other than that honda injectors are noisy.
