dieseldude, share ko lang' may nakausap kase ako na driver ng van, hi ace commuter D4D, same engine ng innova na D4D, almost 4 years na yung van sa kanila' nung nag uusap na kami nagtanong ako sa kanya kung kumusta na ang van nila' kung may naranasan na ba silang may nasira sa makina nila' ang sagot niya sa akin' meron na raw' naka-experience na daw sila na namatayan ng makina' sabi ko mabuti di ho kayo nabangga nung namatayan kayo ng makina at nag o-overtake kayo sa mga truck at bus' ang sagot niya di naman daw kase nasa traffic naman daw sila (pag nasa davao city proper) ang problem daw na na-experience nila eh' yung injection pump daw' di daw nila ma-"bleed" ("bleeding" ba yun sa may injection pump') kase sabi niya yung mga dating hi-ace daw eh' meron nun' TAMA BA si manong driver'??? Delikado mag bleed sa high pressure side ng maski na anong common rail system dahil sa taas ng pressure. Hindi ito ni-rerecommenda ng mga engine manufacturers. Pwede lang mag bleed sa low pressure side (from filter to supply pump). Ginagawa ito kung nag papalit ng fuel filter or supply pump.

tapos yung alternator bearing masyadong maliit daw, nasira daw kaagad yun' ang ginawa nila pinalitan nila at nag oversize sila' Ngayon ko lang nadinig ito. Nasisira ang alternator bearing kung sobra ang tension ng serpentine belt.

tapos meron daw maliit at malaki na strainer ba tawag dun kaya daw minsan eh' sa term ni manong driver eh' parang "duyan" effect ang hi-ace D4D nila' Isa lang ang fuel filter ng Hi Ace.

badtrip pa nga daw si manong driver sa toyota kase pinalitan daw computer box nila worth 160k... Bihira masira ang computer box ng Hi Ace. Maaring masira ito kung pinagalaw nila ang sasakyan sa mekanikong kulang ang experience sa mga electronically managed engines.

kaya yun dun ako nagulat' ang haba na ng kwento ko' pasensya na' naka-D4D din kase ako... gusto ko lang malaman opinion mo kung tama si manong driver...' ok' SALAMAT..... Wag ka matakot, oks naman ang D4D.

ok' Thankz Dieseldude' sana nga ok ang D4D at sana umabot ng 10yrs bago masira ang mga major parts niya para di masakit sa bulsa...'

Depende sa mileage ang buhay ng kotse......hindi sa taon.

1.Gud pm!Tanung ko lang po kung anung problema ng engine na 1kzT Efi na bigla nalang namamatay habang naka-idle or tumatakbo na mismo? Parang may tumutunog na relay before na magauto-off ang engine
-pinacheck ko na fuel line and its ok naman.
-nag change rin kami ng new fuel filter.
Kung napapansin mong bumibitaw ang relay, malamang walng problema ang EFI pump...... nasa electronics ng car ang problem.
2.possible kaya na yung computer box or yung elec.injection pump ang may problema? Anything is possible.......
3.San kaya pwede magpaservice ng injection pump repair ng EFI at magkano kaya or kung surplus magkano rin po kaya? I will send you a PM.
4.Magkano po computer box nito? Hindi ko alam. Bihira ito masira.

Thanks in advance and more power to tsikot.com.

Ang dapat mong gawin ay ipa-diagnose or scan ang car mo...

sir pa pm naman po kung saan nag rerepair of nagbebenta ng new EFI ng avanza 1.3 j nasira kasi nung bagyong ondoy around metro manila po sana or makati thanks po sir

Gas naman siguro ang Avanza mo? Hindi ko maintindihan kung ano ang ibig mong sabihin "EFI". Kung computer box ang tinutukoy mo, bumili ka sa Toyota casa. Nakabili ako nito Monday this week. Toyota price was approx 8k, very reasonable.

Maganda ang ginagawa ng mga casa ngayon. Nagbaba sila ng prices para makatulong sa flood victims. So far, alam kong tumutulong ang Toyota, Hyundai, at Nissan.

Hi can anyone identify these 2 pictures for me? car is a nissan patrol safari 1993 td42

1.) the hose in the picture is not connected to anything. parang putol or ganito ba talaga siya? is this a breather or what? i just wanna make sure kasi baka dapat naka connect to pala to something tas na tanggal lang






2.) what is this hose for? galing siya sa vacuum pump behind the alternator. kaya lng nag leleak ng oil din yung hose nato.
-is there a problem with the vacuum pump or seal?
-mechanic disconnected the terminal na kadugtong nito kasi it keeps the handbreak lights on lagi. baka grounded bec of the oil?




THANK YOU!

I am not sure coz I don't have the vacuum circuit for this vehicle. My mechanic says that this is an idle-up device which should be hooked up to a solenoid valve..






2.) what is this hose for? Not sure again. galing siya sa vacuum pump behind the alternator. kaya lng nag leleak ng oil din yung hose nato.
-is there a problem with the vacuum pump or seal? Possible.
-mechanic disconnected the terminal na kadugtong nito kasi it keeps the handbreak lights on lagi. baka grounded bec of the oil? Something may be wrong with the car's handbrake circuit.




THANK YOU! Try to ask Rion, fellow Tsikoter. He has access to lots of info, and might be able to give you correct info on this car's vacuum lines.

[SIZE=4]i've been reading this thread before office work almost eveyday and i would say that it has been interesting, specially for me who is new to diesel powered vehicle. i bought a 1997 hilander about three months ago. I'm pretty satisfied with its performance, including the suspension and the aircondition system, except for the white smoke and bad odor that comes out of its exhaust. Is it true that the 4ja1 isuzu engine is notorious for its white smoke emissions? i've seen isuzu crosswinds of latest models (which i learned also usues 4ja1 engines) having the same problem on to white smoke emissions.

[SIZE=4]can you share your experiences on 4ja1 isuzu engines? thanks in advance.[/SIZE]

[SIZE=4]i've been reading this thread before office work almost eveyday and i would say that it has been interesting, specially for me who is new to diesel powered vehicle. It's really your posts/questions which make our thread interesting. And I just try to share my experiences with you.

i bought a 1997 hilander about three months ago. I'm pretty satisfied with its performance, including the suspension and the aircondition system, except for the white smoke and bad odor that comes out of its exhaust. Is it true that the 4ja1 isuzu engine is notorious for its white smoke emissions? No it's not true. If your compression is good and you're not burning oil, this could be a timing or a fuel injectoi system problem.

I've seen isuzu crosswinds of latest models (which i learned also use 4ja1 engines) having the same problem on to white smoke emissions. C[/SIZE][SIZE=4]an you share your experiences on 4ja1 isuzu engines? thanks in advance.[/SIZE][SIZE=4] Of course. But I will first ask our technicians if they have noticed a white smoke trend on 4JA1s, then I'll get back to you.
