ok, so tensioner pulley or cam tensioner? I would like to rule out any potentialy dangerous sounds cause right now I am broke. dont think it is internal. if it was valves it would be loud as hell with the oil cap off, right? injector tick would be more consitant, in theory? when I start up it sounds good, than if I rev to 2500 i get teh tick, it sounds "slow" doesent corespond to rpm like it should. than after reved up it ticks at idle.
