Yes sir, pina check ko ulit at sabi ng mechaniko di daw na bleed ng maayos. Salamat po sa inputs. I hope di sana dahilan yung isuzu fuel filter econo parts.

Cheaper ones , we are not sure of the material components utilized....lalo na yang Fuel filter/ Oil Filter.
Salamat kaayu Bay.

OO nga sir, mas mura ung isuzu econo parts kaya i grab it na lang para maka mura. Pero yun sabi ng mechaniko di daw na bleed ng maayos. Sana walang problema talaga ang fuel filter ko na econo parts. Salamat po sa reply.

Mga Sir follow-up question po. Sa fan belts po natin, alin po mas maganda gamitin, yung may ngipin na belt or walang ngipin? and wat brand po?.. Pa cenxa na po sa term, di ko kasi alam anong technical name talaga ng belt..

Thanks for the clarification dre. Another knowledge for me. CDO pod ka? Kabisado man nimo Osmena lagui. Cheers!

I have a 95 Ls Pickup with 4JA1 engine, no problem so far. tried to ask a couple of mechanics to overhaul, ayaw buksan. except for the usual usok. Normal lang daw yung white na usok. hehehe. Problem nga yung mga nang huhuli ng smoke belching. Btw, does anyone know kung ubra mga kabit ng turbo sa stock 4ja1? Anu con's and pro's on having it? How much does it cost?

Just buy a surplus Crosswind turbo. With the low boost (mga 6 psi), it won't require much adjustment to the fuel pump to make it run... just bolt it on and you're done!

You can go one better by using a 4JB1 turbo, but that might require more fabrication and you definitely want to adjust the fuel pump calibration to match the turbine.
