    Hi to all member, My car is lancer 97 carburator engine, tanong ko lang kung normal ba ang maputing usok na lumalabas sa tambutso kapag ka - start palang ng engine or kapag naka stop (neutral) ang kotse?
    Ano ba ang normal na kulay na dapat usok ng tambutso?
    Any opinion sa mga expert dito sa tsikot. thanks.

    Have you checked your motor oil if the level is getting lower?

    Have you had a mechanic adjust your carb recently? Tune up?

    Kung di naman humihina ang makina, at di rin amoy gas o langis, then water vapor lang yan. Nag-condense overnight at nag-steam nung umandar ka at mawawala later. Normal lang yan.

    Pero kung yung nauna ang napansin mo, humina hatak at amoy langis, blow-by na yan. Baba makina.

    Buksan mo yung oil cap habang umaandar. Kapag pati duon malakas ang usok, valve clearances naman ang isyu mo.

    Kumonsulta ka na lang sa trusted mechanic mo. Hamo syang mag troubleshoot.

    mark,
    there are basically three descriptions of the colors of the tailpipe by product: bluish white usually means your engine is burning lube oil from the crankcase from a couple of causes like bad pcv valve, worn piston rings, leaking valve seals, overfilled lubrication system, clogged return (drain holes of the cylinder head) and negative pressure or vacuum in the crankcase of the inlet crankcase filter is clogged. blackish or dark exhaust emissions caused by clogged intake air filter, too rich of an air fuel mixture, bad fuel or improper ignition timing. whitish smoke or steam caused by a blown head gasket(continuous) or only during warmup which is normal. consider this: the fossil fuel you burn in your car is mainly hydrocarbon or hydrogen and carbon atoms mixed into a compound with other impurities as sulfur. if you combine carbon with oxygen which is about 21% of the air we breathe, it becomes carbon dioxide. if you combine hydrogen with oxygen, the product is H2O or water which leaves the exhaust pipe as steam. in this case it is perfectly normal and your engine's combustion is perfect or near perfect.
