Hi,
2.8 Pajero 98, JDM, 4m40 automatic with 180,000 mileage.
Sirs, May humahalong oil sa fuel kaya ang itim ng crudo sa fuel tank, mahina rin ang power.
Hard starting din ba sa umaga?

Ano kaya problem ?
Malamang injection pump ang problem...
-- Mga magkano kaya budget para dito?
thanks...

Sir Dieseldude,
I own an isuzu alterra '07. I had problems with my alternator this morning and as the electrician dismantled the air filter and tubes to view the alternator, i saw some oil in the inner lining of the tubes. There is also some oil residue on the turbo assembly. Maybe is is whats causing thick black smoke whenever i reach above 90km/h or 3,000 rpm. Also sometimes while idling there is minimal black smoke which smells like charcoal (not fowl). With these facts what do you suggest i do? I regularly change oil every 5,000 kms and have my 1 yr old original air filter cleaned. My fuel filter was also replaced by isuzu not more than a year ago. Looking forward for your answer

Hi Dieseldude,
I have a question w/c needs your urgent reply. Just bought a Mitsubishi Adventure last Dec 2011 and just after a month, even after the first 1,000km pms, I encountered a problem. One Sunday, it just didn't start, battery is ok, fuel filter is ok but there is no fuel going to the engine. Towed it to the casa, first they told me its a solenoid problem in the shut-off valve then after that, they want to replace the entire injection pump. My worry is this, my car is brand new, doing that makes my engine a repaired engine, is that type of repair grounds for a replacement? I'm not sure you can answer this since its not really a technical question but I'm just hoping you have an idea since you have a lot of experience.

sir mag kano mag pa linis ng nozzles sa central diesel?

The question should be "magkano ba magpa service ng injectors". Think about this......
1) Injectors and nozzles wear out. This is why spare parts are available.
2) Some nozzles can be re-used, and some just have to go to the trash can.
3) Nozzles coming from poorly maintained engines with very high hours/mileage cannot be put back to service.

Normally, reputable diesel workshops will help you, and they will only replace parts that are found to be unserviceable.
Cleaning can never fix a worn out part.

This is normal. Oil is coming mainly from the PCV and a small amount from the turbo.

Maybe is is whats causing thick black smoke whenever i reach above 90km/h or 3,000 rpm.
Replace you air filter.............

Replace your air filter .................

Casa will not replace a car due to a faulty injection pump.

If I were you, I would accept the replacement pump as long as it is new and carries the original vehicle warranty.

Maybe because it is an assembly that's why they need to replace the entire injection pump even the the shut off valve is only small and there will be no repaired from the engine just the injection pump replacement

Hi Dieseldude,

A year ago every time my speed reaches 60 kmph, I can already hear my turbo whistling. But now, even I have already reached 120-140 kph di ko na naririnig ung dati nya na tunog. Is it because sira ung turbo? or may kailangan ako na check?

please advise.

Thanks.

I will not be concerned about this as you are hitting 120 - 140 kph. Power is good...........turbo is working fine.

Sir,

What's your take on the Bosch CRDi system Foton uses on their 4JB1 turbo motors? Have you had any experience with them already? Anything to watch out for? Are they expensive to service?

The View passenger van is available only with the CRDi engine variant.
