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.

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

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

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.

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.

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?

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.

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

Kung dating wala yan dapat mapa check mo. It can either be a fuel knock or an engine mechanical knock.

I have a 3. 0 fortuner with 60kms on it.* *Yesterday, it suddenly lost power.* As you step on the accelerator, the revs go up, but very slowly.* *No power at all until you reach 3,000rpm (which takes around ten seconds to do so) then the power kicks in.
*
Has anybody experienced this before?* I would appreciate any feedback/tips anyone might be able to provide.* *I do not know where to bring the car because i do not trust toyota casa.* * *

Before anything else, you should have your vehicle scanned for any faults logged in. I will pm you.

thanks, may spare toyota 3c-tdi engine kasi kami, baka puwede ilagay sa aming 3c-td. hehe..

magtatanong lang po ako regarding turbo, yung kasing isuzu mu ng kapatid ko, may problema sa turbo. kung tumatakbo ito below 80kph, ok lang, di mausok. pag lagpas ng 80kph, yun yata ang time na mag kick in ang turbo, biglang bubulwak ang maitim na usok, parang nag le leak yung lubricant ng turbo sa exhaust manifold. kailangan mag slow down at maghintay ng mga 20 minutes bago mawala yung maitim na usok. pag chineck yung engine oil bawas na ito. ang tanong ko ay, pwede ba idisable yung turbo, para maging naturally aspirated ang engine? malaking trabaho ba ang pag convert nito? may effect ba sya sa engine performance? habang nag iipon nang pang repair, ano ang pwede gawin pansamantala para lang mawala yung maitim na usok, habang nasa 80+ ang speed? please help!!
