question regarding valve seal

**vin888** · May 18th, 2005 11:56 PM

pag white smoke na lumalabas meaning nito is sira ang valve seal diba?

ano pala ang nag ca-cause para masira ang valve seal?

it could also be a bad air-fuel mixture in you carburetor.

afrasay akala ko black smoke lalabas pag bad F/A mixture, running rich, pag running lean wala naman ata smoke.

Pag maputi ang usok, malamang valve seal, dati may sasakyan ako, bumaga ng white smoke, nun pinabayaan ko naging black smoke after ilang weeks.

yun pala sire na ang valve seal.

Natural lang masisira ang valve seal, goma lang kasi yan na may spring fastener sa ulo nya, para hindi makapasok oil

yung white smoke pwede rin busted cylinder head gasket, at may pumapasok ng tubig sa chambers, kaya pag combustion, puti usok

same problem as my car now. white smoke coming out of my tambutcho.... sabi nga ng mekanino valve seal. pero dko pa napagawa. magkano umabot yung sayo vin888?

sabi nung siraniko baka kaya nasira yung valve seal ko dahil nung pumutok yung radiator hose ko. few weeks ago.... pero ewan kung dun nga talaga nang galing.. case 2 case basis din cguro yun.

I stand corrected. White pala.

naghahalo na ung tubig at langis mo sa makina kaya kailangan palit head gasket na yan.

patignan mo na rin ung mga piston at valvola nya baka me tama na rin sila.

is it true pag ur driving tapos kulang ang power pinipilit naisisra ang valce seal?

If you get black smoke, it could be your engine is running too rich.

If you get white smoke and you notice that your ride is loosing oil, then the best would be to get a compression test done (wet and dry) first as thatr would help determine whether it is a piston ring, seals, etc...
