    about to finish my DIY car repair (valve lapping, valve seals, gaskets etc...) corolla gl 91

    problema ay yung valve clearance na bago pa man ako nag simula ay mukhang ndi tama so gusto ko siya itama.

    kaso unlike the rocker-arm type na may screw for adjustments ng clearance, yung sa kotse ko ay wala. meron siyang adjusting shim ng papalitan mo kung mali ang sukat. pero mukhang mahal ang prosesong ito na suggested ng repair guide. kasi kelangan pa i-measure ang installed shim using a micrometer (wala ako nito at mukhang mahal ito hehehe) then do the computaions tapos bibili ng bagong shim of the right thickness.

    any alternative method of doing this??? yung kilala ang ginawa niya dati ay tiniyaga niyang hasain yung shim ng kelangan ng adjustment. but the question is paano kung ang kelangan is mas makapal na shim??? may nabibili ba nito sa atin??? although meron naman akong extra shims sa bahay just in case.

    tnx!!!

    To do it right you need to replace the shims and use a feeler gauge.Make sure na adjust muna ang valve, sayang naman ang pinaghirapan mo kung tumukod ang pistons sa valve.Do you know the clay technique?
