Change fuel,oil,air filter. At timing belt. Napakalibrate k0 na rin ganun pa din. Nkpg change na din aq ng glow plug. . Kc sa umaga after heater k0 kundi k0 pa aapakan ang silinyador ayaw mag start prang ayaw umahon ng diesel. Then pg ng start sya tatapakan k0 pa ng 2 or 3 times tap0s ung idle nya mababa pr0 pg ng2l0y na at ung parang di na mamamatay engine ok na per0 maus0k padin blue and white smoke amuy diesel baho ng us0k. Pro kapag tumakb0 na aq nabuga parin ng us0k den after mga 10 to 15 mins driving wala na ung us0k n0rmal na.

Heto payo ko:
1) Check pump to engine timing
2) Check glow plug system
3) Measure engine compression while engine is cold
4) If compression is low, perform engine overhaul.

Pero sa palagay ko, mahina na ang compression ng engine.

sir napa overhaul ko na po eh, gumanda n ung andar at lumakas na humatak nun napa calibrate pr0blem lng tlga pag umaga starting hard starting ayaw umah0n ng diesel prang naghi2ngal0 kundi pa tatapakan ang pedal.. Tap0s maus0k hndi n0rmal. Mawawala lng us0k kpg umandar na tumakb0 ng 15 mins.

Thanks very much sir. sorry but what are the usual internal parts that could go wrong with these pumps? TIA

Seals, lever pin, or even pump housing

Dalawa ang gumawa sa makina mo: yung nag overhaul ng engine chaka yung nag calibrate ng pump. Wala ba silang maipayo sayo sa next step na dapat gawin?

1) Ginawa mo ba yung una kong mga suggestion, lalo na yung compression test sa cold engine?

2) Kung mababa ang compression, hindi okay ang pagka overhaul.

3) Pa recheck mo din ang calibration ng pump sa authorized service center para maka sigurado ka.

Good luck................

medjo ok na po ung adventure namin, pinalinis k0 ung n0zzle P350 then inadjust ung timing ng injecti0n pump. Mdli na sya iistart at d na maxad0 mausok. Lumakas ng k0nte ung hatak nya. May epekto po ba ung advance ang timing ng pump?

Very good.

Shempre, may epekto ang timimg change, retard or advance......depende kung gaano tayo lumalayo sa standard specs.

*Sir Dieseldude,

I have a N/A 4JB1 engine po, meron po bang engine-mods for it? Turbo kit? Any suggestions po for modding my unit and how much will it cost?

thanks!
