    If the cam lobes are worn out, the cam lift and duration (angle of cam rotation from opening to closing) changes and should be replaced. The clearance in the specs should still be followed. If it still makes tappet noise, the cams are either worn out or misadjusted. Or sometimes like on Toyota 22re, 22 rc or 22rte, the tappet adjusting screw end wears out and you thought the clearance was sufficient until the cams rotate. In the latter case, you replace the rocker arm adjusting screw

    Hayz nakwo! Masusunog ang mga valves mo. Look for a trained and knowledgeable technician and stay away from your mechanic

    guys napaayos ko na ung valve clearance sa ibang mekanik, halos wala na pong tunog, mahinang mahina na lang, mawawala na daw un pag bumiyahe ng malayo. ang problema po na lost/lose thread (tama ba) ung isang pinagkakabitan ng screw ng valve cover, parang hindi kasing higpit nung iba. magleleak po ba un? anu po pedeng remedyo dun? tia..

    Lose thread po. Some machine shops have the tools and know how to fix this. They can re-thread or re-tap that to original. In case of severe damage, slightly bigger diameter tap is needed. And the valve cover screw hole has to be machined. Machine shops can do this and tell you where to get the appropriate screw/bolt needed.

    They just need to use a tap and dye set. It shouldn't cost much.

    As for leaks I dont know.
