Glow Plugs(White and Blue smoke)

**acenie** · January 10th, 2005 01:23 PM

Encounter again prooblem to my l300.
Pag Cold Start(especially in the Morning) my white and blue smoke coming from the exshaust and rough idle. Pero kung mainit na ang engine wala naman usok at saka smooth idle pa. Sabi ng mekaniko Injection pump calibration, pero pag mainit naman ang makina ok naman. Meron kayang dead na Glow Plugs.

how long do you glow the plugs in teh morning??

may glow plug light that comes on when you switch on the car.. and it comes off around 7 seconds or so that signifies usually that the glowing is enough (it doenst mean that teh glowing has stopped). try waiting for a little more.. maybe count to 10 seconds when you put the key in the ON position before you start...

dapat mahirap mag-start yan kung may defect yung glow plugs or rough idle nga pagka-start kung isa sa glow plugs di gumagana. better take them off and check them one by one.

sakit ng 4D56 talaga ang hard starting lalo na sa umaga...damn!!!

blue smoke is bad = oil in combustion chamber

hirap start na 4d56 = usually fouled up na 1 or more na glow plug, palit lang solution diyan, maybe 20 min DIY.

acenie,

kapag white smoke ibig sabihin nun may langis (baka may tagas) kung glow plug kasi ang problema mo that means hard starting ka sa umaga (but i beg to disagree na hard starting ang 4D56). kapag mainit na ba yung makina at nirebolusyon mo wala nang white smoke?

white smoke sa diesel = normal sa unang start. kasi hindi masunog ng mabuti yung diesel dahil yung compression ng diesel fuel e hindi pa na compress ng mabuti (malamig pa yung makina).

reason = hindi pa na achieve yung optimal temp ng makina, kasi ang engine block ng karamihang diesel (although merong bago na aluminum na) e iron. matagal painitin.

gas engine, pag 1st start white smoke = water vapor = normal

kung matagal na at mainit na makina at may white smoke maaaring yung coolant na mi mix sa fuel mo = Bad.

blue smoke = definitely BIG problem.

pag bibili ako ng glow plugs: is there a specific brand I look for?

and what is the fair price for them?

indi sila parepareho, bring ur stock plugs, para makita yung length.

Choose Japs instead of Taiwans, If I remember correctly around 180 yata isa. (tagal na e sensiya na)
