    kung nababasa ng langis ang plugs, pwede valve seals ang may problema. baka lumutong na kaya tumatagas...

    pwede rin na oil seals sa may spark plug.

    para naman malaman kung blow by na talaga ang engine, fitst get a compression tester.

    do the dry compression test first then log the figures. next is do the wet test. put few drops of oil sa spark plug hole. kapag tumaas ang reading, piston ring ang problem. full overhaul na kailangan mo.

    kung hindi tumaas reading after the wet test, valve seals lng may problema. either top overhaul or ipdukot mo sa mekaniko yung seals.

    sir sirkosero, i have a failed valve seal, i just dont know kung same ang technology behind ph16a and 2e, sa akin walang oil sa spark plugs, pero sablay na valve seal ko. kinalabasan top overhaul.

    kung oil seal naman, yes agree, pwedeng dukutin, pero di ba dapat ung langis sa ibabaw ng spark plug pupunta not sa burning tip? same what hapoened to my b14gen2, ga13ds engine.

    ^^^ sir mike, pano mo nasabi, kung ganon, parang wala ng lubricating effect ang oil at malulusaw ang oil ng gasoline, so papalya na talaga piston rings mo at cylinder block.

    kung may usok, well, pwedeng top overhaul, pero in your case, full overhaul ang assessment ko. medyo madugong repair din yan, at IMHO, kung top overhaul lang, okay pa, pero kung full overhaul, bili na lang ng sariwang engine din.

    IMHO, AFAIK, HTH.

    sa akin kasi, dapat ung sentra b14gen2 dapat binilhan na alng ng engine, kesa full overhaul, almost cost the same.

    depende sa usok. ano kulay? bluish-white ba? kung oo, burning oil ka na. pinaka mahina dyan top overhaul.

    ano pala ibig sabihin ng naghalo langis at gasolina? maamoy lang ba? may konting trace ng gas na nahahalo sa langis. konti lang.

    kung yung itsura ng langis mo ay parang kape with creamer, blown head gasket yan. top overhaul plus baka machine shop pa

    Older cars have a limit of material removed during resurfacing of 0.020(twaintee thousandths) of an inch after which you discard the cylinder head. With today's bimetallic or aluminum engines it is highly discouraged that you have the cylinder head resurfaced. They are made thin enough to reduce the weight. Check the head for warpage first. Of course the machine shop will not refuse your money.



    By the way, you can replace the valve seals without having to remove the cylinder head.

    Yung sa Usok po sir eh parang usok ng sigarilyo eh parang bluish white nga po, ung sa mixture ng gas and oil po eh aun nga may konting gas na sa langis parang nag halo na po pero konti lang yung gas and regarding dun sa amoy po, pag ikaw yung nasa likod ng auto habang naandar eh iba na yung aamoy na galing sa muffler
