Which line? There are lines for vacuum pump,intercooler, aircon step up, two going to the injection pump if mechanical not sure if EFI has.

lahat po tinanggal niya. from injection pump to egr valves at idle compensator , 4wd hub lock . gusto ko sana ikabit di ko alam gamit sa mga bilog na mukhang filters

tried guessing naging mausuk sa exhaust, sa inter cooler meron po dalawa isa sa manifold, yung isa sa parang actuator di ko mahulaan saan papunta. sana po matulungan niyo ako malayo kasi sa amin zamb pa local isuzu subdealer says no shop manual daw sila

I see. EFI ba unit mo? Medyo iba ng kaunti ang routing natin dahil sa EGR. Will try to take a picture of similar units so you will have an idea. Basics on the system is every hose is dependent on the boost/vacuum. Diaphrams will open at higher boost based on fuel output and high EGT for recirculation. knowing the rout/nipple for openning the diaphram then this is for boost source.

Sir hindi pa po EFI. Bale subic po ito coverted 1994-1996 4jg2tc engine bighorn Irmster (hope spelling correct). 148000 kms on it. problem ko talaga sa ngayon ay sa intercooler actuator lagi na full open (di ko ma hulaan saan ito ikakabit) ang vacuum line papunta actuator, tried to connect to vacuum port nag uusok at no power sa hatak. di ba masira engine ko nito kung iwan ko open na lang at huwag ikabit actuator intercooler (full open).

tried to connect intake manifold nipple hose directly to injection pump vacuum hose fuel compensator medyo nawala ang usok. gusto ko irev at sukatin manifold pressure pero takot ako madamage engine kasi di ko malaman kung ok lang full open ang intake manifold ng inter cooler, kung i rev ko ng husto. sa menor no pressure ang manifold kasi.

Naghanap ako ng kamukha ng bighorn dito iba ang laman nila. (mas luma kasi itong akin)

paano ba malaman kung timing belt or gear type ito without openning engine.

saka ko na lang paganahin ang 4wd and inportante umandar engine and EGR.

meron din mga tatlo round parang check valves di ko rin alam paano ikabit, isa pink, isa blue at isang maliit puti lang kulay. yung blue and pink check valves (one way hangin) yung maliit baliktaran ang hangin pero meron resistance konti (number on side of each round thing blue, pink, white is Aisin 4d21 Aisin 4d25, 4d22, respectively)



Hintay na lang po ako ng inputs ninyo..

Thank you

naalala ko tuloy yung Van namin. some stupid mechanics removed the vacuum lines, peru mali-mali ang pag sauli. ang dami ng solenoid kasi eh...

worst, naging problema yung shifting ng A/T. very very late up-shifting, too early downshifting, less responsive... and super shift shocks.

got help from a Toyota Van forum, but by the time I got the vacuum lines fixed. the clutch of the a/t is damaged na...

I suggest, hingi ka nalang po ng Pic from fellow owners. that's what I did.

and replied with a colored trace of the same pic they provided to me, to confirm it na tama ba gawa ko.
