Good morning Mr. Chua,

My name is Jay de Vera and I’ve recently come across an old post of yours in the Tsikot Forum about the problem you had with your 2003 trooper. I’ve recently purchased a second hand trooper November of last year and 2 months after I had to take it to Isuzu Pasig for PMS and they had me replace 3 components, a throttle positioning sensor, an oil pressure sensor and an Oil pressure valve. I asked if my injectors had a problem, they said that it didn’t. Until last week! I noticed a decrease in power and after returning it to Isuzu Pasig they said that the Oil and Coolant are mixing and that my Cylinder head needs to be replaced. Estimate is at 200K just for the head! That was when I saw your post and am now finding a way to solve my problem. I hope you could extend your experience on this matter to help a fellow victim. Thank you.

good day sir i know someone who does oil and coolant mixing, coolant and diesel fuel mixing all they have done is replace the oring of the injector sleeve... injector sleeve has two oring upper and lower if i remember correctly lower oring prevents mixing of water and fuel while the upper prevents mixing of oil and coolant..worse case scenario is replace the injector sleeve...but then again there are still conditions that the head is really blown or has a leak it is when the injector sleeve is removed and by seeing the inside of the head if there is any form of rust/cavitation then its time to replace the head...the mechanic is from pampanga sir...pm me sir if you are interested...

by the way the oring deterioration (or worst case head with cavitaion/rust)is most often associated with not replacing coolant or by not even using coolant...

Good Evng. I have an 2003 Isuzu Trooper 4jx1 engine local edition

1) napansin ko na "nagrarattle" ang steering wheel sa trooper ko when i reach more than 70 to 80 km. tapos parang nagvibrate ung mga gilid ng door. considering na due na ang pagpalit ng gulong sa front. pinalitan ko ng 2 new tires sa harap.pinacheck ko wheel alignemnt at camber - ok naman. wlang probelma daw sabi ng yokohama mekaniko. after this i experience steering and door upholstery rattle at 70 km. pero when i release (mawawal ung rattle) then pagtapak ko naman. minsan it will rattle or wala. can u help me this

2) last week, ung trooper sabi ng kapatid ko. iba ung tunog ng engine. so pinatingin namin sa mekaniko. sabi nya. palit air filter (wla na weird sound) at ok na ung takbo fom 0 to 60km.. tapos pagtapak ng gasolina. ayaw mag pick up (takbo agad) kahit nasa 20 to 40km parang hindi kaya ng trooper na takbo agad. pls help

3) kung nakabilad sa init. ayaw talaga lumamig at nasa traffic. pero kung sa gabi at kahit nasa traffic (malamig ung aircon)

4) how will you know na hindi bagay ung atf na ginamit mo?

thank you

1. try to check the upper and lower suspension bushing and also the balljoints...
2. it sounds transmision problem...pati yung pagrattle more than 70-80kph ang takbo may be asociated with the transmision..
3. try mo magpalinis ng ac...it will cost you around 2500-3000

good eveng sir

1) pinalitan na namin lower and upper balljoint, stabilizer, upper and lower suspesion bushing(front and back)
2) after that pinawheel alignemnt ok naman ang alignment. pina wheelbalancing ang front kasi doon ang bago (un parin mag raratle kung tatakbo 70 to 80) pero hindi mu tapak ng gas pedal. ok naman. then ok naman (pawala wala ung rattle after u reach 60) - may recommended na trusted mechanic?
3) bago lang palinis sir. malamig sa gabi. hindi kaya ng aircon na nakabilad sa init at traffic
