Mga sir.

Newbie question lang po. I just got a '03 trooper na skyroof 4jx1 engine (ODO 69500 kms) a few days ago. Nag pa change oil ako sa petron using Besco oil 10w30 and original filters at nagpalit ng mga fan belts. Ang haba kasi pila sa kasa kaya petron ako tumuloy. Pagkatapos change oil, pauwi na ako sa bahay nahalata ko na everytime inaapakan ko ng mabigat ang gas pedal may parang tumutunog na fan belt/ parang hangin na hirap higupin ng engine. Binawasan ko yung apak ko para mawala yung tunog.
Nung mag park na ako sa isang grocery bigla na lang namatay makina. Sinubukan ko start pero ayaw na. We towed it to Isuzu (casa).

May naka experience na ba ng ganito sa inyo ?

nochemd, Interesting yang experience mo. I have same model trooper as yours, 68k on the odo & happy with it so far. It's not the oil - Besco 10W/30 naman yung oil mo. Yung iba kasing tumirik na trooper gumamit ng thicker oil - dapat 05W/30 or 10W/30 lang para sa CRDI engine natin. Hindi ka ba nag overheat? Pa check mo rin timing belt. Keep us posted. Thanks.

nochemd, kung injectors nga yan & since nasa isuzu casa na yung trooper mo they should replace the injectors free of charge for as long as the failure is not due to misuse or abuse. They wrote letters regarding this to trooper owners - ask a copy from the previous owner. Pa check mo rin yung RPCV [rail pressure control valve], injector sleeves, injection system wire harness - 6 years na rin kasi trooper natin.

Thanks for the replies.
I justr talked with the Isuzu Service supervisor this morning. He feels that the sensors (RPCV and something else ) caused the problem. He also told me that If the original owner didn't change the recalled injectors, he would replace it for FREE.

Hopefully walang ibang problema para less gastos. Will keep posting here for updates.

I like the size and shape of the trooper and that is the reason why I bought it. I just have a couple of questions for the owners of the Isuzu Trooper 2003 Skyroof.

1. How long will it take before I can get my ride back assuming that the injectors and sensors caused the problem ?

2. Has anyone here tried converting/changing the engine of this trooper model ? What engine did you use ? How much did everything cost ?

Thanks in advance

Update lang po.
Nakuha ko na trooper ko from casa. Sensors lang problema. Pero had it checked by a person who knows turbos. Bumigay na turbo ko. I had him rebuild the turbo. Hindi na siya ngayon bearing type.

problema ko lang. Bakit mula nung kinuha ko sa kas mausok na siya (puti ata ).
Injectors na ba ito ?

Please help.
