As of last Tuesday, same problem pa rin. Nagdecide kami na dalhin ko yun sasakyan sa CDC once magkaroon ako ng free time. May hinala na rin kasi kami ng erpats ko na injection pump problem na ito.

Found this bro, I think ito problem mo.

Solution is to replace the front oil seal and a gasket na din sa injection pump gear. Andyan yung zexel part number.

i have a 2006 bongo with J2 engine. Where in cebu City can i have the fuel pump calabration increased by 2%?
i have gone to 3 different places, an no one seams to know what i mean ( i added a turbo so i need 2% more fuel over the complete rpm range)

Sir Dieseldude,

I have a 1995 A/T Pajero with 4M40 engine (Japan unit). It is about to reach 160,000 kms this year. I regularly replace my engine oil, air filter, oil filter, and fuel filter every 5000 kms. Turbo is ok, rebuilt 4 yrs ago, wala naman leaks. So far, the condition of the car is ok, one click in the morning, no idling issues, never been calibrated and replaced timing chain. Napapansin ko lang na medyo malakas na konsumo (estimate ko is 6 to 7 kms per liter) and medyo struggling on ascents and reaching 100 kph.

Since I want to avoid future problems, I just need your professional advice regarding the ff.:

1) Is my nozzle tips due for replacement already? Is this one of the reason for high f/c?

2) Since my timing chain is not yet rattling, adviseable ba na palitan na to, including tensioners and sprockets?

3) How about injection pump, would you suggest to calibrate it already kahit na wala hard starting or smoke belching (but mine emits smoke under load...3k rpms or more)? Would calibration at this mileage recommended, to improve my f/c, acceleration, etc. May isa kasing Zexel shop na nagsabi baka kinakapos ng fuel delivery yung pump kaya nahihirapan sa rekta....would you agree on this?

4) Is it possible to test injection pump performance without taking it out of the engine?

5) My friend said that Japan 4M40 and its rotary injection pump is slightly different from the local 4M40, ano po ba ang pagkakaiba nito? Do you have calibration data for Japan units?

Thank you very much. Hope to visit your shop one day.

Hi sirs,

Im a total newbie regarding automotives.
My ride was a Mitsubishi Adventure 2008 GLS Sport
About 80k yung mileage. Since my family migrated on US eh binigay na ito sa akin ng father ko. The catch is kilala ko yung father ko na hindi maalaga sa sasakyan

Ask ko lang po if anu ang frequency ng pagchange ng fuel filter? Need po ba na dapat isabay ito sa oil change? BTW about oil change eh yung ako na humawak ng sasakyan eh semi-synthetic na lage ko pinapaoil change which is di ko alam kung ok na ba yung mineral or fully synthetic dapat so nagstick ako sa mid nung dalawa, nasales talk ata kasi ako ng Shell station sa amin na lagi ko pinagpapachangoil.

TIA

Ask ko lang po if anu ang frequency ng pagchange ng fuel filter? Replace at least once a year. Need po ba na dapat isabay ito sa oil change? Hindi. BTW about oil change eh yung ako na humawak ng sasakyan eh semi-synthetic na lage ko pinapaoil change which is di ko alam kung ok na ba yung mineral or fully synthetic dapat so nagstick ako sa mid nung dalawa, nasales talk ata kasi ako ng Shell station sa amin na lagi ko pinagpapachangoil. Sundin mo yung nakasulat sa owner's manual.

Sir Dieseldude,

I have a 1995 A/T Pajero with 4M40 engine (Japan unit). It is about to reach 160,000 kms this year. I regularly replace my engine oil, air filter, oil filter, and fuel filter every 5000 kms.

Since I want to avoid future problems, I just need your professional advice regarding the ff.:

1) Is my nozzle tips due for replacement already? Is this one of the reason for high f/c? It depends on the nozzles' spray pattern.

2) Since my timing chain is not yet rattling, adviseable ba na palitan na to, including tensioners and sprockets? If I were you, I won't replace it.

3) How about injection pump, would you suggest to calibrate it already kahit na wala hard starting or smoke belching (but mine emits smoke under load...3k rpms or more)? Would calibration at this mileage recommended, to improve my f/c, acceleration, etc. May isa kasing Zexel shop na nagsabi baka kinakapos ng fuel delivery yung pump kaya nahihirapan sa rekta....would you agree on this? Your engine may be starved of air. Check your air filter and turbo boost pressure first,

4) Is it possible to test injection pump performance without taking it out of the engine? No way..

5) My friend said that Japan 4M40 and its rotary injection pump is slightly different from the local 4M40, ano po ba ang pagkakaiba nito? Do you have calibration data for Japan units? Yes we have it, we have a complete set of Zexel calibration info.

Thank you very much. Hope to visit your shop one day.
