if major repair, sa casa na lang po kahit wala na warranty yon sasakyan at least pwede mo siya ibalik kung sakali na mag leak muli, kesa paulit ulit lang ang repair, lalo lang maragdagan ang gastos mo.

Hi,

I have a mechanic replaced the oil seal of the rear of transmission, the part that connected to propeller. But after a few days, I noticed that there is still a little drop of oil. Can anyone suggest what could be the other problem? is the seal not fitted properly (note: its an OEM Isuzu with correct part number). Hope someone can advise.

Thanks

same sa akin yon pa balik-balik ang leak. Na resolved finally when we had the propeller shaft machined. Kailangan smooth yong area where the oil seal touches.

Guys,

Can someone help to pin point where is the fuel pump of 4Ja1. I got something on the service manual but sort of confusing since its only a black and white drawing. I need to check on it but can having a hard time to locate.

THanks.

Problem solved..nagtono lang ng injector..lakas na ngaun hatak..wala na din kadyot.. tinaasan din nya yung menor at yung idle speed pag aircon on..di ko nagustuhan kasi feeling ko malakas sa diesel pag ganon. nagbasa ako na manual sobra sobra sa recommended na rpm speed.kaya binalik ko sa tamang timpla ung idle..ok na sya ngayon.
