rasambo:

do you have any smoke when you start up in the morning? what color? white or black? naka on ba ang CHECK ENGINE light mo?

ano ang nangyare sa kotse before nag simula ito? nag over heat ba? nag change oil? more details give way to a better diagnosis.

Good morning sirs,



Can you recommend a good, reliable and affordable shop that can clean nozzles/check injection pumps? My hi-lander is nearing 180k kms, medyo mausok na rin even after it has warmed up. Ok naman power pero would like to have it checked just the same.


Thanks in advance!

First step: Check & replace Fuel Filter/Air cleaner. Replace if necessary, and see if emission improves.

180k kms is quite high....definitely, some wear on the engine and fuel system. "Just cleaning" is a misconception. When you bring your pump/injectors to a reputable shop, injectors are cleaned, tested for spray pattern, opening pressure, and backleakage. If failed, parts need to be replaced and calibrated to specs. etc...Pumps, cleaned, disassembled, parts inspected, replaced as needed, then mounted on test bench for calibration (bringing it back to original OE/like new condition)

Regarding smoke: White smoke would indicate a possible engine problem. Black smoke will most likely be related to your fuel systems (pump and Injectors), or air starvation.

Bear in mind that your vehicle has accumulated a lot of mileage.

thanks dieseldude! I regularly change my fuel and air filters eery 5k kms, but it still smokes. can you recommend me a good shop that can do all of these? mine has white smoke by the way.

Hi DieselDude,

tanong ko lang...nagtataka kasi ako kung bakit yung mga diesel engine dito sa atin eh parang ang bilis ata umusok lalo na yung Isuzu? Pero sa ibang countries naman eh hindi. I have a van kasi na galing japan and 260,xxx na yung ODO niya eh hindi naman mausok at wala naman prob sa engine...Ano ba ang mayron sa makina ng mga sasakyan sa ibang banda na wala yung makita dito sa atin?

sir, bakit kaya hanggang 120km/hr lang ang top speed ng nissan frontier ko 2000 model 4x2 90km mileage, kahit off na ang a/c ko. para kasing pigil siya humatak pero tahimik naman at walang usok.

Baka barado ang fuel and/or air filter.

Or baka naman accelerator cable adjustment lang...... Pag sagad ng accelerator pedal, dapat sumagad rin ang injection pump lever sa maximum speed stopper bolt.

Kung hindi mag-improve, baka injection pump calibration ang kelangan.

Siguro dahil sa poor maintenance sa atin; baka dahil din sa kagipitan sa datong. Puro tayo remedyo at di nasusunod ang regular service schedules. Maayos siguro ang pagkaka-maintain ng ride mo kaya mahaba ang buhay.

Marami din diesel workshops dito na kulang sa training, technical information, at test equipment. Sa ibang bansa, umaandar ang batas lalo sa emission, malaki ang penalty at di malalagyan ang nanghuhuli. Dito, sa sobrang gustong makatipid, yan ang tawag na "napapamurang mahal". Pag di tama ang trabaho, umiiksi ang buhay ng makina natin.

Oil change has no effect on smoke.

Does white smoke diminish as temperature increases?

If it does, you will most likely need an engine overhaul. But do a compression test just to make sure.

actually mausok pa rin even after the engine has warmed up.

what's a good place to have it checked, ok ba sa central diesel?


thanks!

not seen any of the signs of trouble you mentioned above except dun sa pagstart ng sasakyan may lalabas na black smoke pero isang buga lang kasi raw diesel siya sir. Pero napacheck ko na most likely engine support raw sir

[Dieseldude]

not seen any of the signs of trouble you mentioned above except dun sa pagstart ng sasakyan may lalabas na black smoke pero isang buga lang kasi raw diesel siya sir. Normal ito......

Pero napacheck ko na most likely engine support raw sir. Walang relasyon ang smoke sa engine support.......unless meron reklamong malakas na vibration.
