Diesel Fuel Injection System Help Desk

[torogi kid]

magtatanong lang po ako regarding turbo, yung kasing isuzu mu ng kapatid ko, may problema sa turbo. kung tumatakbo ito below 80kph, ok lang, di mausok. pag lagpas ng 80kph, yun yata ang time na mag kick in ang turbo, biglang bubulwak ang maitim na usok, parang nag le leak yung lubricant ng turbo sa exhaust manifold. kailangan mag slow down at maghintay ng mga 20 minutes bago mawala yung maitim na usok. pag chineck yung engine oil bawas na ito. Check mo muna ang PCV. Baka nag re-release lang ito ng oil gasses sa intake system at nasisipsip ng turbo.

ang tanong ko ay, pwede ba idisable yung turbo, para maging naturally aspirated ang engine? Pwede.

malaking trabaho ba ang pag convert nito? Malaking trabaho ang conversion. Malaki din ang gastos nito.

may effect ba sya sa engine performance? Oo.....laki bawas sa pwersa.

habang nag iipon nang pang repair, ano ang pwede gawin pansamantala para lang mawala yung maitim na usok, habang nasa 80+ ang speed? Gamitin mo lang hanggan 79 kph.

please help!! Patingnan mo muna ang sasakyan mo sa magaling na diesel workshop para malaman mo kung ano talaga ang sira. Baka okay pa ang turbo.....

thanks DD, will try it one at a time..

Nakakasipsip lang siguro ng hangin sa filter housing or fittings. Inspect mo nang mabuti ang oring seal sa takip. Baka matigas na ang oring, o baka nasugatan ito nung ibinabalik mo ang takip.

Sir DieselDude,

One happy customer with Central Diesel. Sir Jake, Antonio, Karen, Nonoy, Cons, thanks for taking care of my ride. Sir Jake I didn't had the chance to meet you personally sir but your staff was very accomodating and courteous. I just had my innova supply pump replaced yesterday, tried it, drove it, no problem wala ng stalling, choking at pino na ang takbo. I would recommend Central Diesel anytime. Two thumbs-up sir Jake. Thanks again.

Happy to be of service to you. Would have been nice to meet a fellow tsikoter. I was probably out on a client call when you came. Drop by anytime when you are in the area.

Sir DieselDude,
Thank you for fixing my Fuego problem, nag iistart na siya at umaandar...although after 2 days nabitin ako climbing a steep road after shifting to second gear....ayaw tumuloy ng krudo hangang sa nag stall na....i just did a manual pump of the fuel filter and then umandar na....sometimes then the idling would go down so kailangan ko bombahin...i guess that's the drawback for using surplus parts...no guarantee on when it will fail....the staff of Central Diesel were very accomodating and as written in the post they would not jump into telling you to replace this and that without testing....regards to Karen, Antonio, Jayson and Miss Inday for making my puyat worthwhile.

hello. just seeking advice seeing that this thread has been very helpful. have a starex vgt recently serviced for 15k pms. i think it has lost power. some of the symptoms are: 1. upon initial start, it shakes about 4 or 5 times like it is losing its going to die then it normalizes. 2. when in 2nd gear, it sometimes gets stuck at 2k rpm. pushing the pedal further does not elicit any response. pumping the gas pedal 2, 3 or 4 times will let it speed away. 3. i have a hard time overtaking. i dont get the turbo feel it seems. however it still reaches 160kph. just brought it to baguio but i felt the power loss more going up kennon. really had to push and pump gas pedal. i told the casa about this but during testing they said they didnt feel what i described. however they said their gds is broken. i think its the device that reads the car computer. i was asked to bring it to another casa which is notorious for ridiculous charging. they have a gds that works. pls help so that i can avoid getting duped. ty!

Your car within warranty? Is your "check engine light" on? Does engine smoke a lot, black or white smoke? Have you checked/replaced your fuel filter?

i told the casa about this but during testing they said they didnt feel what i described. This is possible if the fault is intermittent. Fault may not have been active when you visited casa.

however they said their gds is broken. i think its the device that reads the car computer. Correct, GDS is their scan tool.

i was asked to bring it to another casa which is notorious for ridiculous charging. they have a gds that works. pls help so that i can avoid getting duped. ty! I will PM you.

there is no check engine light. fuel filter was replaced about a year ago when i did my 10k km pms.

This is possible if the fault is intermittent. Fault may not have been active when you visited casa. got it.

Correct, GDS is their scan tool.

I will PM you. [/QUOTE] i got your pm. thank you.
