Sir Dieseldude good morning po,.ask ko lan where to find your calibration shop, pcheck-up ko yun mb100 ko. twice na ko nagpalit ng injection pump pero ganun pa rin laging nanginginig at malakas na galaw ng makina. newly replaced na rin nozzle tip pero ganun pa rin nandun pa rin un knocking sound. Thanks!

This pump really has a problem (malakas ang galaw ng makina) it has to be modified!

mga bro,may nakapag palit na ba nang suction valve sya yung nagbibigay nang krudo papunta sa makina, malapit sya sa injection pump, innova diesel 2006 akin automatic, nasira kc yung akin lumalabas check engine, tapos sa casa lng ba talaga ako makakabili 5777 pesos kc sa casa di pa nila ako bentahan pag di sa kanila ipa service 1008 labor.meron na ba naka encounter nito ty

mga master need advice, meron ako starex 1999 model. our old mechanic advised us na tanggalin na ung TURBO kasi sira na daw, he closed lahat ng daanan ng oil, and water. as i expect humina hatak ng starex, dinala namin sa shop para totally tanggalin ung TURBO. that was a year ago. ngayon blow-by ung makina ng starex i was thinking kung papalitan ko na makina or overhaul lang??? ano po ba mas maganda? nag canvass ako dito sa cavite ng d4bh na makina and it cost 70-85k kasama na ung turbo ung wala naman nasa 50k ganun ba talaga price ng d4bh? kung overhaul magkano kaya aabutin? and saan maganda magpagawa? na trauma na kasi kami dati iniwan namin sa casa pag uwi ng van may tama sa bumber. baka may kilala kayong magaling na mechanic dito sa kami sa GMA, cavite.

TIA

if 70k kasama na turbo, i think i prefer change engine, if you have a good mechanic to choose the engine for you.

I will see. We are still conducting an investigation on this matter.

Sir DD, any news po sa crd injectors? TIA

[Dieseldude]

Sir DD, any news po sa crd injectors? TIA

Ford CR injector failure was due to a maxxed out aftermarket device to greatly increase horsepower and torque. These injectors are very reliable, but they are not designed to take misuse and abuse.

I will not mention the make/brand of the device as this is unfair. Problem was not on the device itself, but on the setup/adjustment.

Sir DD,

Pinalitan ang fuel filter kasi nagpugak pugak nawala ang hatak. ngayon okey naman sya. problema pag sa umaga cold start nagvavibrate mababa ang RPM so apak muna sa gas pedal hanggang 750rpm. pero pag normal temp na ang makina okey naman.
Tanong ko lang tungkol sa fuel check valve for 4ja1 ito ba yong kinakabitan ng fuel filter mismo? magkano kaya price nito?
kasi nga nagbasa ako dito baka daw bumabalik ang fuel sa tank kasi nga not good na baka ang fuel check valve.
Thanks in advance more power...

[Dieseldude]

Pinalitan ang fuel filter kasi nagpugak pugak nawala ang hatak. Nagsimula ba ang bagong problem pagkatapos ka magpalit ng filter?

ngayon okey naman sya. problema pag sa umaga cold start nagvavibrate mababa ang RPM so apak muna sa gas pedal hanggang 750rpm. pero pag normal temp na ang makina okey naman. Meron white smoke sa cold start? Ano mileage ng car mo?


Tanong ko lang tungkol sa fuel check valve for 4ja1 ito ba yong kinakabitan ng fuel filter mismo? Yes. magkano kaya price nito? Di ko alam.


kasi nga nagbasa ako dito baka daw bumabalik ang fuel sa tank kasi nga not good na baka ang fuel check valve. Possible... Baka sobra lapot ng lube oil mo? Medyo lumalamig na ang panahon natin.

Thanks in advance more power... You're welcome...

ngayon okey naman sya. problema pag sa umaga cold start nagvavibrate mababa ang RPM so apak muna sa gas pedal hanggang 750rpm. pero pag normal temp na ang makina okey naman. Meron white smoke sa cold start? Ano mileage ng car mo? YES sir, as in. 2000 model 77+++ di ko sure kong tama kasi 2nd owner na ako.

pero nong nag long trip ako kahapon to batangas di naman masyado umuusok ng puti.

once again thanks.
sir pa pm naman ng shop address.

[Dieseldude]

once again thanks.
sir pa pm naman ng shop address.

I will pm you.

Did your engine experience overheat situation/s in the past?

White smoke is an indication of poor compression and/or wrong/erratic injection timing.

DD,

the casa diagnosed that my turbo for the grand starex is defective due to actuator problem. Talaga bang papalitan yun buong assembly? Di daw bumubuka yun turbo vanes (not exactly sure of the term used). If I use it still with a turbo not functioning, will it damage the engine?

TIA.

Di daw bumubuka yun turbo vanes (not exactly sure of the term used). If I use it still with a turbo not functioning, will it damage the engine? No it will not. But you won't have sufficient power.

Is your grand out of warranty?

Hello guys and to sir DD,

Just a few days before i changed the head gasket, starting was lazy.

after the head gasket replacement, starting was again alive and kicking.

but just after 2 weeks of daily driving, lazy starting seems to be coming back again.

haven't reached yet the minimum 500 km for retightening headbolts

i retightened bolts as to specs using a torque wrench. i didn't prime the injectors before installion during the reassembly. i just cranked the engine several times. but during the cranking, i heard a "tik-tak" sound when i let go the switch. i rechecked the timing marks but they are not off. even before cranking/starting i checked the timing marks several times just to be sure.

power is unusually low also. oil is leaking at the compressor side of the turbo.

what could lead again to lazy starting? are my headbolts coming off again? by lazy i mean the cranking rpm is unusually low. engine is 4d56B turbo. actual engine mileage is unknown since engine was changed before we bought the ride. kindly enlighten me sirs. TIA

Cylinder head bolt should be properly torqued during cyl head installation..... no retorque is required.

i retightened bolts as to specs using a torque wrench. i didn't prime the injectors before installion during the reassembly. i just cranked the engine several times. but during the cranking, i heard a "tik-tak" sound when i let go the switch. i rechecked the timing marks but they are not off. even before cranking/starting i checked the timing marks several times just to be sure. Unusual sound is probably due to a sticking nozzle.

power is unusually low also. oil is leaking at the compressor side of the turbo. Repair the turbo.

what could lead again to lazy starting? are my headbolts coming off again? Blown head gasket if your previous torque was insufficient.

by lazy i mean the cranking rpm is unusually low. engine is 4d56B turbo. actual engine mileage is unknown since engine was changed before we bought the ride. kindly enlighten me sirs. TIA. Weak battery, poor cable connections, bad starter.......

Sir DD, sorry at la na me time mag-back read sa thread kaya ask ko na lang directly.

I just bought 1995 mdl 5dr JDM 4m40 TDIC pajero with rotary type injection system na may 85,000 odo reading. Changed all oils (engine, transmission, diff, tranfer case) and oil filter, air filter but not yet the fuel filter. I did the washer mod also.

Before malakas and itim na usok kapag tumkabo siya ng matagal na. The I disabled the EGR at yun nawala na yung black smoke. It is easy to start even in early morning after may ulan pa yan nang magdamag so I think ok naman glow plugs ko. However, 4.8-5 km/ltr lng FC ko. I know that it is the first A/T for me at medyo nag-aadjust pa me pero parang ang baba lang talaga ng FC ko eh. Ok naman ang gear change ng pajero, 1,500rpm to 2nd gear, 2,100rpm sa 3rd gear at 2,400 sa 4th gear. I always use OD on, A/C on at puro city driving lang at hindi naman malala traffic flow sa Puerto Princesa City.

Ano kaya problem, nozzle tip lang or fuel pump? would you advice na nozzles lang muna palitan ko and then kapag hindi nag-improve FC sa 6-7km/ltr bago ko na ipa-check fuel pump?

[Dieseldude]

I'm not sure as I haven't actually seen your car.

Offhand, I would have the injection pump serviced as it controls rpm and fuelling quantity.

Dieseldude!

tanong ko lang kung bakit naging delayed yung shifting ng pajero ko after magpacalibrate? sa inyo po ako nagpagwa mag 2weeks ago na pero before naman magpacalibrate ok naman shifting ko ngayon ang hirap pumasok ng 2nd gear at 3rd minsan hanggang 40 lang ang natatakbo ko kasi ayaw mag engage ng gears at pakiramdam ko tumigas yung pedal ko 2days ago ko naramdaman yung pag tigas ng pedal. Babalik ako tom sa CDC andun kaya ikaw tom?

[miked]

dieseldude

my engine overheats faster than before prior to the HG replacement. would an injection timing be the cause? during the reassembly i accidentally rotated the IP sprocket about 1.5 turns cw when installing the timing belt.... engine power also feels lower plus it seems my FC increased. engine is 4D56B air cooled turbo

i replaced and retightened all loose bolts connecting battery and starter motor yet it still starts at a lower rpm.

TIA
