White smoke during start-up

[RedHotBlood]

What could be wrong sa van ko, during start ups mausok sya na puti pero pag mainit na makina wala na as in normal. Yung acceleration nya at condition pag naandar eh ok naman. Palagi to lalo na pag umaga o naipark ko na ng matagal, minsan i thought it was the glowplugs pero 1 click lang start na engine eh. Sabi pag glow plugs hard starting daw? Your infos would be highly appreciated.

white smoke means there is oil in the fuel mixture. could be oil is seeping or leaking into the cylinder while you are parked.

could be moisture sa internal structure? particularly in the exhaust department? "kadalasan" normal lang yan sa cold climates.

dont worry too much...

anyways, do you find your van drinking too much engine oil? as in nababawasan ang oil mu in an strange manner. bigla na lang nababawasan? eto yung mga symptoms na may oil nga sa air-fuel mixture which means your engine is burning oil.

or during cold start lang ba ito?

What is the make and model of your van/engine?

the man is talking about glow plugs. the engine is diesel, talking about air fuel mixture is for spark ignited gasoline engines. if the smoke was continuous, yes, it could be too much oil but it would cause the diesel engine to runaway (high uncontrollable engine speed) until the engine blows apart

Correction lang po for everyone's knowledge on smoky exhaust. From the book
AUTOMOTIVE TUNEUP by William Crouse & Donald L. Anglin, chapter 34 page 365 ang reference.

SMOKEY EXHAUST : 1. Blue smoke - Excessive Oil Consumption
2. Black smoke - Excessively rich mixture. Meaning
more fuel.
3. White smoke - Steam in exhaust. Meaning there's
water.

RedHotBlood,
Any comments on the replies?

[Dieseldude]

From experience, white smoke when cold is often indicative of low cylinder compression, mostly on high mileage engines....... wear on piston rings and cylinder walls. Compression improves when hot due to thermal expansion of pistons.

guys sorry po for my late reply, ganun pa din po van ko tuwing umaga. Now to answer your post one by one:
1.) Make and Model - 4m40 / '96 Spacegear 4wd 80k mileage
2.) Napansin ko lang na may parang film ng oil sa exhaust manifold connecting dun sa engine block, pero di naman nagbabawas.
3.) May nagsabi sa akin na mechanic na baka daw nozzle tip, but not sure ako dun.
4.) Pwede yung sinabi ni dieseldude pero 80k pa lang yung van ko and wala kong ibang problems except for that cold start with white smoke.

eto pa, pag start nanginginig yung engine pero after 30 to 40 seconds eh ok na yung tining (tunog) nung makina, naisip ko baka fuel filter though nakabili na ko di ko pa napapalitan, pero nagtataka ko bakit me white smoke as in white (hindi blue) and tuwing lumalamig lang sya nagkakaganun?

yung air filter ko may breather na nakakabit from the engine cover, napansin ko may oil film is this normal? Kelangan ko na yata magpalit ng air filter to isolate it one at a time. Please continue to pour in your comments mga peeps! thanks!

makasabat na din,, ganyn din kia pregio ko sa cold start laging puti usok at me nginig pero pag after 40 50 sec ok na pati usok waLA NA,, wierd pero di naman overheating,walang presure, sa tingin ko sa injection pump parang wala sa timing or naka advance settings
