Valve tappet clearance adjustment

[jick.cejoco]

ahh ok po thanks. dun sa sinabi ng mekanik na 1 week pa daw bago mawala ung tik tik na tunog kasi unti unti daw ang paglapat ng valves, totoo po ba to? tsaka dun sa sinabi nia na hindi na dapat sundin ung clearance sa manual kasi hindi na bago ung sasakyan?

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

ang nasa manual po .20mm sa intake at .25mm sa exhaust. ang ginawang adjustment, .15mm sa intake at .16mm sa exhaust. so mali po ung adjustment? hindi ko na po aantayin na maka1 week?

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

sinabi ko na na ung nasa manual ang kulit , pag luma daw iba na....
maraming salamat sir jick.

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.

sir mahal po ba magparethread? . posible po ba magleak un? kung hindi magleak, iwan ko na lang munang ganun? thanks

[luffin]

sir mahal ba magpare thread? magleleak po kaya un?. kung hindi magleak, hayaan ko na lang muna? thanks

[StockEngine]

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

As for leaks I dont know.

[luffin]

okay sir, thanks!

pwede ka rin gumamit ng helicoil kit. pwede mo na i-diy lang. sa benavidez meron nun

[luffin]

mga sir magkano po ba yan helicoil? meron po ba nian sa mga auto supply? hindi ko po alam kung saan yang benavidez, taga laguna po ako. thanks

[sirkosero]

around 700 sa benavidez, kanto ng recto. sa yale hardware

[luffin]

napansin ko din po na mejo gumanda ung hatak between 1k - 2k rpm, pero parang humina naman ung 2k rpm pataas ung parang galit na galit ung makina. dati shift ako between 2k -2.5k rpm. ngayon po bago mag 2k nagshishift na ko. malakas po ata un sa gas? normal ba yun pag bagong adjust valve?

[luffin]

thanks po sir sirkosero. naibiyahe ko na ung auto, wala naman leak pero 1 oras lang. tingnan ko po muna kung magleak sa mga susunod na araw.
