Masyadong mabilis mag-carbon!!! help!

[NoOne]

hello peeps,
I got my ride fixed 2 weeks ago. Napansin ko lang, parang ang bilis magkaroon ng carbon yung tambucho ko.. kapag unang arangkada, ang dami mag-emit ng black smoke. Tried washing it out with water, putting the water hose inside tambucho, but after 2 days, parang ganun na naman karami kaya ang usok ko ulit.
I ask the mechanic who fixed it, sabi nya normal lang daw to, linisin ko na lang lagi ng linisin.. duh! meron bang ganun!

need your expert advice.

salamat po ng marami.

Sir anong inayos? Yun bang injector pump at fuel injectors? Baka malakas masyado ang bugso ng diesel from the injectors kaya mabilis magkaroon ng carbon ang tambutso ninyo.........

ang pinaayos ko talaga is yung turbo. umuusok kasi dati ng puti. I think nagleleak yung oil from the turbo to the exhaust manifold kaya white yung smoke. Alam ko inadjust din nila yung injectors dahil kahit na noong maayos yung turbo usok pa rin ng usok. If i'm not mistaken yung pressure bago nila ginalaw is 80, and sabi noong expert technician nila i-adjust daw sa 150. don't know kung doon nga nila ina-adjust yun sasakyan kaso since then, mas mausok na itim na kaysa sa puti...

i think rich ang mixture mo.

u must target the root of the problem: your engine. have the fuel injectors adjusted or have ur engine "carbon-cleaned".

anong car ito?

kung maitim na usok, pwede manggaling sa:
1. Defective na fuel injection pump.
2. Blowby na engine.
3. Defective na turbo.
4. Maruming air filter.

Kung maputi ang usok, pwede manggaling sa:
1. Injectors
