How was your visit to the casa? Share mo naman dito sa forum.

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.

di kaya sir napalitan na yang mga injectors ng mga sira na talaga?
*DD maaari bang malaman kung ginalaw na ng casa yung engine nya particularly the injectors?

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

[Paj699]

Wrong type, dieseldude po yun

[halimaw]

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!

Inaadjust ang injector/nozzle para umayon sa calibration specifications. Ito lang ang tamang adjustment; ito din ang pinaka-matipid na adjustment. Pwede i-adjust ang lumang nozzles kung okay pa ang kundisyon nito. Pinapalitan ang sirang nozzle.

sir, considering po na binuksan nila ang makina without my authorization, ano po kaya ang magandang gawin sa bagay na ito? nakausap na po namin ang OIC sa service pero wla ring nangyari. would a complaint with the DTI consumer protection desk suffice or is it better to file a criminal complaint with the court? by the way sir, how much will it cost for the check up of the injectors? thanks

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. Madaming montero sa kalye......hindi naman sila mausok.

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. That's good to know. Nag improve din ba ang power?

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. Hindi ko alam.

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? Less sulfur means less lubrication. But it depends on the formulation. I haven't really studied this matter.

Or safe naman ikarga euro4/5 ng unioil seaoil diesel on older engines as is without adding 2T. I don't know. But I'm quite sure that these new players have studied their fuel's applicability to our market.
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? Di ko pa naaral ang effects ng 2T oil. Pero kung ganyan mix ratio, palagay ko okay lang.
Thanks MasterDD in advance!

sir dieseldude, anong problem ng engine kung sa may dipstick may steam na lumalabas? blowby na ba yun?
mausok rin yung exhaust ko ng puti during idle and gear shifting pero konti lang.

[kompressor]

Dieseldude,


I noticed that I started having fuel backflow problems after I replaced my fuel filter. The former one was an Asahi brand while the replacement was something really el cheapo (Sakura or something similar sounding) as I had no time to get one during the time I changed it. Do diesel fuel filters also have one way valves like those in oil filters?

If not, how about feed/primer pumps? Are they equipped with a one way valve? Or am I missing a fuel check valve along my fuel plumbing?

[Dieseldude]

sir, considering po na binuksan nila ang makina without my authorization, ano po kaya ang magandang gawin sa bagay na ito? Did they totally disassemble the engine, or injectors and supply pump lang?

nakausap na po namin ang OIC sa service pero wla ring nangyari. would a complaint with the DTI consumer protection desk suffice or is it better to file a criminal complaint with the court? This not my line. You can consult a lawyer about this.

by the way sir, how much will it cost for the check up of the injectors? I will PM you.

thanks You're welcome...

[Dieseldude]

sir dieseldude, anong problem ng engine kung sa may dipstick may steam na lumalabas? blowby na ba yun? Of course blowby yan. Pero normal ang blowby sa lahat ng engines, bago or luma. Lumalakas ang blowby habang naluluma ang engine.

mausok rin yung exhaust ko ng puti during idle and gear shifting pero konti lang. Mahirap ito sagutin. Ipa-check mo sa diesel specialist workshop ang car mo. Maraming pinanggagalingan ang white smoke......wrong timing?

Btw....sabihin mo naman kung ano ang make/model ng car mo next time...

[dingch]

Sir Deiseldude,

I acquired a 1998 Adventure GLS M/T Dsl. Its in running condition, not really worn looking. Aircon is ok, instrument panel is also working. 110k sa odometer, hindi naman na-ondoy.

Its my first time to handle a diesel car/engine.

I dont hav a background as to its maintenance or repair history so i plan to have it checked. Parang general checkp. so my question is this:

What are the parts/components that need
1) replacing outright
2) adjustment or repair
3) checking

Like for example, sabi ng driver namin, change oil na agad along with filters since we dont know when was the last change oil. Palitan ko ba lahat ng mga belts? Any particular belt na dapat pinaka importante mapalitan? Fuel pumps? Compression test ba?

Is calibration in order na? Kelangan ba ipacheck ang fuel injection (i just read this from another thread).

Meron bang common electrical issue ang adventure na dapat unahan ko na at maipagawa?

May nakabudget ako na money for engine rehab na around 20-30k kung talagang kailangan.


THanks dude!

What are the parts/components that need
1) replacing outright: Replace timing belts and tensioners
2) adjustment or repair: Check/replace brake pads/shoes, check handbrake adjustment, check tire wear.....wheel alignment if necessary
3) checking: Check for cracked/weak coolant hoses, intake air hoses, and fan belts, check coolant additive

Like for example, sabi ng driver namin, change oil na agad along with filters since we dont know when was the last change oil. Correct, replace fuel and air filters.
Palitan ko ba lahat ng mga belts? Better.
Any particular belt na dapat pinaka importante mapalitan? Timing belts and tensioners.
Fuel pumps? No
Compression test ba? No

Is calibration in order na? Kelangan ba ipacheck ang fuel injection (i just read this from another thread). No if it's running well and doesn't smoke..

Meron bang common electrical issue ang adventure na dapat unahan ko na at maipagawa? Depends on what you see..

May nakabudget ako na money for engine rehab na around 20-30k kung talagang kailangan. Okay na yan...

sorry sir, nakalimutan ko hehe isuzu ls/tfr 1994 model.
pansin ko po kasi hindi ganun kalakas yung white smoke pag idle pero mapapansin mo na may usok talaga.. tapos pag nag sshift po ako sa 3rd gear makikita mo nag eemit ng medyo makapal na white smoke.. sa 3rd gear lang nangyayari sir..
