whats happening to my patrol?

[boybi]

tuwing umaga (or after more than halfday hindi pinaandar yung engine) parang palyado yung engine. mabilis lang naman mag-start, kaso pagnaka idle na, biglang pumupugak-pugak yung engine, pag hindi ko alalayan ng accelerator, siguradong patay ang makina. pero after ma-warm-up na, normal na yung engine. nagpalit na ako ng fuel filters. ano kaya problem?

[roydok]

Baka nga malamig lang nga ang engine.

[Ungas]

Malamang may singaw po yung water indicator sa ilalim ng fuel filter nyo. Or hindi maganda ang pagkakabit nito. Check your fuel line for any indication that air could go in with your fuel. Pag tumagal pa yan, biglang hihinto ang makina kasi nahahaluan ng hangin yung diesel fuel papasok sa injection pump.

[boybi]

pano ba ma-check kung me butas ang fuel line?

[Ungas]

Ang alam kong paraan sina-unang style, baklas-kabit lahat ng hoses. Re-tighten everything that I suspected loose.

[boybi]

kung me butas nga ang fuel line, bakit pag warmed up na ok na yung engine?

[Ungas]

Kahit mainit na ang makina wala nang pugak? Or have you noticed that your idling is a bit low than it was before?

[boybi]

pag mainit na yung makina, hindi na pumupugak. even after 1hr nang naka patay yung engine, tapos i-start ko wala ng pugak. pero pag yung needle ng temp gauge nasa extreme left (coldest) na, then start ko yung engine, me pugak na ulit.

nasa around 800rpm naman yung idling speed.

[Ungas]

Diesel yan di ba? San ka nagpalit ng fuel filters? Did it just hapen after you change them?

[boybi]

yup, diesel. nagkakaganito na kaya nagpapalit ako ng fuel filters. nung natanggal na pala yung isang filter, sira yung o-ring nya. sabi ng mekaniko yun daw malamang ang cause ng pagpugak ng engine.yup, diesel. nagkakaganito na kaya nagpapalit ako ng fuel filters. nung natanggal na pala yung isang filter, sira yung o-ring nya. sabi ng mekaniko yun daw malamang ang cause ng pagpugak ng engine.

[Ungas]

Try to open the o-ring part again, baka nung ibinalik naipit ulit. Ganyan din nangyari sa D4BB engine ko last month lang, nag umpisa sa pag pugak lang pag malamig, hinayaan ko umandar hanggang kahit mainit ang makina bigla na lang namamatay. I had to restart over and over gain just to get back to the service center that made the job. Nagkamali sila ng pag fit dun sa water level indicator, forced entry, sira ang threads. Buti na lang pinalitan nila ng bago.

[boybi]

pero bakit pag mainit na yung engine, normal na ang andar? yan lang ang pinagtatakhan ko. :roll:

[Ungas]

Kasi umaandar na yung makina and injection pumps. Nagkakaroon ng diesel sa fuel line mo. But your engine is sometimes burning not enough fuel in its chamber. Buti nga hindi mo pa naranasan ng blank combustion, parang palyado ang isang butas ng makina. This could be bad for your engine. Lalo na may nabasa ako somewhere that the 3.0L TDI ng Nissan has a bad reputation for cracking under pressure. Just a word of caution.

[boybi]

feeling ko nga parang blank combustion na yung nangyayari. pa-check ko nga agad tomorrow.

[Ungas]

Try to refit all the parts that comes to and from your fuel filters. Mas maganda kung may teflon tape na kasabay para sure na minimize yung sinagaw kung meron man. Good luck! :D

[boybi]

thanks, suggest ko yan sa mekaniko.

[Ungas]

Try to check them for bubbles using soap suds. Bubula ito kapag may hangin na papasok or palabas. Then feel it with your fingers kung meron pa ring diesel around the area.

Old or new model patrol?
If new, ask for warranty repair.
If old, how many Km does it have? Do you have a fuel filter and a water separator? Either one could have a leak.

[kimpOy]

i bleed mo yan sir boybi!
check your manual

[boybi]

jackaroo
