huh where exactly is that grommet? Yeah this is my 5th toy. I had 2 tacomas with this same engine and they did not tick like this. Official verdict from toy dealer is that it needs a valve adjustment with possible sissor gear? While in there they will also change timing belt. Est is $700! They said there could also be damage to the head and then it could get real costly but they cant tell me till they open it up. ???
