Help!!!dead Spark Plug!!! Namamatay Makina

[ambotech]

thanks sa post,,,, kung ang paguusapan ay smoke, wala akong napapansin na smoke eh, malinis lang siya.. walang white, dark or blue-gray smoke, kaya iyon ang pinagtataka ko eh, parang may internal problem siya pero di mo makikita sa smoke na may problema. pag ganitong situation ano kaya sira? sa valve guide ot valve steam lang ba siya?

then one more thing magkano rough stimate na gastos if worst scenario :
top overhaul ?P______
general overhaul?P______

[dennis powell]

sorry, no idea sa price kung magkano.

[ambotech]

pero pag colorless ang smoke at malinis, sa tingin niyo po may sira kaya ako sa
-worn oil control ring or oil ring or
-worn or scored cylinder walls ???

Did you have someone step on the accelarator while you observe the exhaust from the tail pipe or did you rev the engine yourself while observing the exhaust from the rear/side view mirror? Kung tinitignan mo lang from the mirror, baka di mo lang na pansin yun smoke.

Are the deposits from the spark plugs oily? Could they be sooty instead?

Di pa naman sira yun mga plugs mo, konting linis lang yan till you figure out what's really wrong.

Am no expert, but if there are unusually heavy deposits on your plugs I believe that there should be visible smoke from your exhaust.

what I observe dun sa sparkplug ay oily dun sa tip and then dirty siya na color black.

sabi nya kasi after a days lang pagkareplace nung spark,palyado na kaagad ang makina and pag check ng spark plug,they seen oil deposit on tip of it.

accelerate for a couple of seconds or a minute and not a second only (rev it to 2000 to 3000 rpm).

gusto pa sana kitang turuan kung paano madetermine kung alin talaga ang may problema para di ka na gagastos ng malaki and sigurado pa,gawin mo muna pa compression test and tell me which cylinder had the lowest number (normal compression:14-18 psi and should not exceed 18 psi the difference between each cylinder).

i need to sleep na,pwede tom na lang.

* ambotech, do you notice irregular oil consumption? If this is the case then its a worn-out valve seals which only a top overhaul requires. Oil going to your engine plugs is cause by worn-out seals Top overhaul will only cost you roughly to P2k+ to a trustworthy mechanic's labor excluding parts. Ensure that cooling jackets should be cleaned as well prior engine top re-assembly. Good luck.

to leinahtan, hindi naman siya nagbabawas ng langis, kasi december ko pa siya pinachange oil, hangang ngayon ay full pa siya.

to mark powell, saan kaya ako pwedeng magpacompresion test? lahat ba ng service bay or casa meron non? and how much will it cost me?
