hi po dieseldude. gusto po sana naming ilipat ng ibang shop ang alterra and have it checked thereat pero di na umaandar. the mechanic informed us na it is because of the damaged injectors and suction control valve problem. my family had decided to ltercontinue with the suggested repair by isuzu davao that offered a 20% discount on parts and labor sa 184+ na expense kesa ipa-tow pa ang car papunta sa ibang shop. sabi din kasi ng ibang shop na pinuntahan namin e baka ipasa ng isuzu ang liability sa shop na sasalo sa alterra pagpinull-out dun. ang plano muna namin ngaun is ipatanggal ang damaged injectors sa alterra and have them checked for a second opinion sa ibang shop. do you think this is wise? mga magkano kaya pacheck? we just hope na di nila pinalitan ng totoong damaged injectors yung sa amin.

sobrang bad trip na talaga kami ngaun sa isuzu. actually, 2nd major repair na to. the engine control unit was replaced in mid-2010 dahil nasira din. after this mess, we intend to dispose of our alterra this year, which we now believe has several design flaws.

The problem in your area is the absence of qualified independent workshops that can provide expert second opinion and service support on common rail diesel systems.

ang plano muna namin ngaun is ipatanggal ang damaged injectors sa alterra and have them checked for a second opinion sa ibang shop. do you think this is wise? Yes, this is correct. Have the supply pump and injectors tested by a qualified workshop.

mga magkano kaya pacheck? I will PM you.

we just hope na di nila pinalitan ng totoong damaged injectors yung sa amin. You can go to the casa and request them to pull down the pump and injectors in your presence. Did you previously authorize them to pull down your injectors? I recall that this car was sent to them for change oil and clutch service only.

*DD maaari bang malaman kung ginalaw na ng casa yung engine nya particularly the injectors? Oo, kung marunong ang tumitingin.

Hi DieselDude,

You seem to be in the know regarding Diesel Engines, and I am contemplating to jump into the Diesel arena. I have Nissan Vanette with a gas engine, and am a bit torn between maintaining the gas engine, or should I convert to diesel, perhaps a d4bx (4d56) engine.

I am, however, at the moment unable to find a reliable shop that would help me with the conversion process.

I'd like to hear your thoughts on this matter, if it is even possible (or a good idea) to convert to a diesel engine or not.

Looking forward to your reply.

I don't recommend it. You can do the calculations. To calculate, you need the following info:
1) Your approximate travel distance per year
2) Number of years you intend to keep the Vanette after conversion
3) Cost per liter of gasoline and diesel fuel
4) Fuel consumption of your gasoline engine and estimated fuel consumption your desired diesel engine
5) Approximate cost of conversion

Do the math, and you will come up with a sound decision. Good Luck

Sir dieselsude nozzle ba ng 4m40 pwede adjust para tumipid sa diesel or kailangan palitan ng bagong nozzle tnx sir

Kamusta po idol DieselDude...
Dati po mausok yung Fieldmaster lalu pag sudden acceleration, pina-tuneup changeoil palit bago air/fuel/oil filters ganun pa din. May mechanic po nagsabi sakin na posible din daw na nasa quality ng diesel kaya mausok madumi daw diesel natin sa pinas, example pa nya may mga bagong montero nga daw wala pa plaka mausok na.
After browsing some forum, nabasa ko po about Euro4 and Euro5 compliant Diesel fuel which is cleaner daw. Ang nabanggit po is Unioil Euro4 and Seaoil Euro5. Big3 is Euro2 only.
Kaya sir, tried Unioil, after a couple of Fills with unioil napansin ko very less smoke na nga kahit sudden acceleration or pataas ang daan need to step more sa pedal di na nga mausok.

Question ko po, totoo po ba na posibleng by using cleaner euro4/5 compliant diesel e mawala ang emission ng black smoke or nagkataon lang yung experience ko.

Another question po, I read na euro4/5 diesel has less sulfur that can adversely affect older diesel engines due to lack of lubrication etc, totoo po ba to sir? Or safe naman ikarga euro4/5 ng unioil seaoil diesel on older engines as is without adding 2T.
To counter this naglalagay din po ako ng 2T oil 200ml/50L mix po, so far so good naman, lesser vibration and better response. Wala po ba bad effect ang 2T oil sa older diesel engines like 4m40 fieldmaster?
Thanks MasterDD in advance!
