eto yung pics.. yung itim na hose di ba yun ang PCV. tama po ba? tapos sa kabilang dulo eh naka konekta sa air intake manifold..visible yung mga oil residue di po ba?

Nasa valve cover ang pcv. Hose connects pcv to air intake manifold.

sir dieseldude meron po akong MB100 since 2000 po hindi pa din na cacalibrate.... hindi din po mausok kahit floor mo pa pedal... hindi din po nagbago ang f.c.

pero hindi na maganda ang idling the rpm is moving up and down pag naka menor at naka off ang a.c. at may vibration na din po... kahit rev. ko meron pa din vibration
Yan ang madalas na reklamo ng mb100. Injection pump ang problem.
Check mo din engine/transmission supports.



ano po kaya ang problema?

[/QUOTE]

i already change tranny and engine support last year po... ganun pad in may vibration pa din... ( double check ko din po)

sir may filter or screen filter ba sa loob ang injection pump ng mb100?

kailangan po bang ibaba ang injection pump ko?

or hintayin ko nalang tuluyan bumigay? like puti usok, palyado or malakas sa diesel, etc...

5 yrs. na po kasing ganun yun sa matagal ko nang hinihintay bumigay para isang gawaan nalang....

sir if ever it needs to be calibrated much better po ba kung bibile nalang ako ng surplus na sariwa pa? nakakakuha po kasi ako ng murang INJECTION pump na pang mb.

sir yung original na nozzle ko ay bosch pinalitan ko ng replacement lang na korea... ang napancin ko sir pag naka floor ang gas pedal between 1k hangang 3.4rpm walang usok kahit kunti pero pag ang rpm ay tumuntong na ng 3.5k may usok na po ng kunti.(if you are the one driving its not visible pero kung papasilip ko sa sakay ko yung tambutso meron na daw ng kunti... pero dati nung bosch pa ang noozle ko kahit hindi ko pinapahasa totally po walang usok kahit kunti.. ano po ang ibig sabihin nun? mahinang klase yung noozle na pinalit ko?

sir pacensya na sir ang dami kung tanong...

*DD kung titingnan yung picture saan kaya nanggagaling yung oil residue.. posible ba na merong nahahalong langis sa hose?

[Dieseldude]

DD kung titingnan yung picture saan kaya nanggagaling yung oil residue..
Baka may butas ang hose o maluwag ang hose clamp.

posible ba na merong nahahalong langis sa hose?
Shempre, may kahalong konting langis sa hose...

Injection pump nyan ang madalas nagloloko.

Wala..


kailangan po bang ibaba ang injection pump ko?
Yes...

or hintayin ko nalang tuluyan bumigay? like puti usok, palyado or malakas sa diesel, etc...
Decision mo yan...

5 yrs. na po kasing ganun yun sa matagal ko nang hinihintay bumigay para isang gawaan nalang....

sir if ever it needs to be calibrated much better po ba kung bibile nalang ako ng surplus na sariwa pa? nakakakuha po kasi ako ng murang INJECTION pump na pang mb. Pwede, basta meron warranty...

sir yung original na nozzle ko ay bosch pinalitan ko ng replacement lang na korea... ang napancin ko sir pag naka floor ang gas pedal between 1k hangang 3.4rpm walang usok kahit kunti pero pag ang rpm ay tumuntong na ng 3.5k may usok na po ng kunti.(if you are the one driving its not visible pero kung papasilip ko sa sakay ko yung tambutso meron na daw ng kunti... pero dati nung bosch pa ang noozle ko kahit hindi ko pinapahasa totally po walang usok kahit kunti.. ano po ang ibig sabihin nun? mahinang klase yung noozle na pinalit ko?
Hindi ko alam.

sir pacensya na sir ang dami kung tanong...
No problem....

Dieseldud, question regarding euro4 diesel.

I've read somewhere before that using this diesel will shrink the seals of the injection pump of the older vehicles. This will obviously need repairing. But after repairing, will the new seals be able to handle ULSD already?

Thanks

I haven't studied the pros and cons of using ultra low sulfur diesel.

Excessive mix ratio of bio fuel with diesel can damage rubber reals.

thanks sir DIESELDUDE...

magpapalit nalang ako injection pump... may warranty naman po sila...

[Derk07]

Your pump has been pulled down......will check later today.

Madami ang causes ng low power. 4M41 is an electronic engine. It needs to be scanned for faults.

Sir DD ano po nakakabit sa 4M40 engine timing belt o timing chain? TIA

Dapat ma scan muna ang car mo para hindi tayo nanghuhula.

Sir Diesel Dude,
Is it possible to repair the TPS (throttle position sensor) of the injection pump of my kia carnival? Casa people says that the the the TPS of my IP is already malfunctioning and needs replacement. However, they do not already have that part on their inventory and advised us to look for that in the surplus shops or replace the whole IP assembly altogether.
BTW, symptoms manifested are: difficulty in acceleration as if the the AT is stuck at 2nd gear and high RPM with low speed. If ever, could you repair the TPS in my IP and how much? BTW, it is a KIA Carnival 2001 model, TY in advance...

Hi jabr.....I am not sure if your TPS can be repaired. It depends on what the actual failure is. Can you post your IP assembly number?

[jabr]

Hi sir Diesel Dude,
Was able to buy a surplus TPS in Banawe and had it installed at casa, car is now running fine. Casa people erased the DTC pertaining to the malfunctioning TPS. Indeed, the TPS was already at fault, the neck of the vane/propeller like thing inside the TPS was already broken in two. I was not able to get the parts number of the IP, but noted that it was from Bosch. TY for your help anyway and more power to you.....
