    Mga Guru's ask ko lang po sana kung bakit po kaya after mga 5 mins of reving up, nagkakaroon po ng medyo white smoke sa tambutso ko po, tsaka medyo umaamoy ng unting fuel/oil. Hindi po kaya dahil sa hindi pa ko nagpapa change oil and tune up?? anuh po kaya problem? My ride is sentra eccs Tnx..

    most probably sira na ang piston ring. kapag may white smoke at madalas ka magdagdag ng oil sign na yun ng sira na ang piston ring. may tawag sa repair na gagawin dyan, "dukot" palit ng piston ring, head gasket etc.

    If it is white smoke the head gasket gone. unfortunately you wil have to take the head off and replace a new one!

    If it is blue smoke your burning oil because on your engine needs new valve seals, not that expensive of a job you just replace the seals.

    So make sure which one of the two.

    pag nag babawas ng coolant , head gasket or the head itself

    pag nagbabawas ng engine oil , make sure the pcv system is good .

    possible seals or rings

    pag malakas sa gas , feedback ba ang carb?

    possible sensor problem

    para makasigurado ipasyal mo sa trusted mechanic

    white smoke po lumalabas, pero hindi naman po ganun kagrabe yung pag-usok nya at hindi rin po saya nagbabawas ng Engine Oil. Tyaka medyo amoy Gas po kasi minsan. How much po kaya aabutin kung papalitan lng mga valve seals, pcv valves?? Kaya po kaya to ng shell service, gusto ko na rin sana isabay kasi sa pag Tune up and Change Oil para isang palitan nalang. Last question po, pagkano po HeadGasket and piston ring?? Tnx po sa lahat ng inputs sirs. at least medyo my cons na ko sa problem. TIA

    Before doing anything, compression test will answer most of your questions before determining what to do. Speedyfix has the equipment to do so.

    Bili kanang cylinder head gasket for that model. Most of the time yan ang problema sa umuusok nang puti dahil may tagas na ang gasket, if not could be a crack in cylider head. So lets hope for the best dahil mahal ang cylider head.

    Yong amoy gas naman maaring rich in mixture ang caburador mo(if carburated) or leak in fuel line or due to unburn gas from engine or just need a tune up.

    The thing is how old is your car? All of this will come in time dahil sa age ng sasakyan. Bakit hindi mo nalang pa-valve job ang cylider head para malaman kung may crack o wala at gaganda pa ang peformance ng makina.

    About Shell mechanic. I dont know kung makakaya nila you just have to found it yourself. Good luck

    kung magpapalit u ng piston ring syempre oversize n yan.. dahil may tinatawag tyo trust side and non trust side sa cylinder bore po.. sinusukat yan by inside micrometer caliper po.. mostly mga .25 mm ang dagdag nyan po.. depende kung first 2nd or third repair na po.. and depende din po kung may scored na yung cylinder wall. malalim na gasgas po un... 2 po kasi ang gasgas sa cylinder wall po ridge and scored.. tnx..

    nangyari na yan sa kotse namin. nagpalit ng piston ring, head gasket and valve seal. top overhaul daw yata yun. original parts binili namin kaya nasa 6k. 4k ung labor kasi mahal doon sa shop na yun. pasensya na kasi hindi aq expert.

    observe mo muna , kung nagbabawas ng coolant, cylinder head or gasket

    kung nagbabawas ng engine oil, seals or rings , or pcv valve
