Hi sir DD. Just when i thought ok yung pajero did 3.2 ko, eto na problema. Tumataas temp nya at napupunta coolant sa reserve. Nag konsulta ako sa mekaniko at sinabi nya na malamang daw ay yung thermostat. Bumili naman ako at tapos na mapalitan ganun pa rin. Umuusok rin sya ng puti pag bagong start, pero pag mainit na engine nawawala naman. Sabi ng mekaniko dapat daw palitan yung radiator cap at yung cylinder head gasket dahil tubig daw yung usok na puti. Ano sa palagay mo problema neto sir? Me posibilidad din kaya na sa turbo may problema? Ty in advance sir DD. Btw sir, nasa abroad ako ngayun, as much as gusto ko dalhin jan sasakyan hindi ko magawa kaya bayaw ko nag aasikaso ng sasakyan. Ty sa advice sir.

Walang relasyon sa turbo ang problem mo.
Thorough inspection ang kelangan before you do anything.
Nauubos ba ang coolant mo?

Hi all,

I need help on my '98 Mitsubishi Adventure, 4D56 Engine.

1st During cold start po, mausok siya, white smoke coming out continuously, pero mag mainit na, wala naman na, at parang sinisinok yung makina, lakas din ng vibration. I have 4 glowplugs replaced less than 3 months ago. normal ba to sa lumang diesel engine? This could be an engine and/or injection pump problem.

2nd is Black smoke coming out kapag pa-ahon or arangkada.
Replace air filter and/or calibrate injection pump if black smoke is still present after replacing air filter.

hindi ko na alam saan ako magsisimula, kasi po this past few years madami nadin akong pinagawa dito sa truck ko, since I'm kinda restoring it and doing preventive maintenance. eto po mga pinagawa ko;

Engine calibrated back in December of 2011.
Nozzle tips replaced around July 2012.
Last change oil Sept. of 2013.

My aim now is to eliminate if not reduce this black smoke coming out. nakakahiya minsan nag i-slow down mga nasa likod ko pag umaarangkada, tapos minsan nag ba-bright pa ng ilaw. heheh Nakakahiya talaga, nag aaksaya ka pa ng diesel, at kulang power mo.

Sir regarding injector nozzle :, due to a bad experienced about clogged or bad spray pattern, would you recommend to check first the cleaning of an injector fluid preferably before a long provincial sunday trip in order to avoid unnecessary problem and just how much is the prevailing nozzle cleaning service fee and do i have to watch out for the technician as the tip might be replaced? TIA

If you are you thinking of using an injector cleaning fluid, I don't know if it really works.
Dirty nozzles can sometimes be cleaned; faulty nozzles cannot be cleaned.

Ty sa reply sir dd, yeah nauubos. Ang nangyari, pinalitan na head gasket, pinarepace syempre sa machine shop ok na. Me problema na naman na nakita, yung puller ng turbo, me play daw. Umaalog sa madaling salita. Pina recondition yung turbo pero me konting usok pa rin, sa egr daw me leak. me butas sa madaling salita. Ang ginawa ng mekaniko sir, bypass ng egr. Ngayun wala ng usok, pero duda ako kase kasama ng design ng sasakyan yung egr dba? Ano kaya pwede gawin sir, hayaan ko naka block yung egr o kailangan ko bumili nito. Thanks again sir dd..

Thanks you sa reply sir DD. May isa pa ko tanong, sabi ng bayaw ko yung thermostat ng ck ko tinanggal yung valve, ibig sabihin free flowing na yung coolant na sabi nung mekaniko ok lng daw kase di na mag ooverheat. Napansin nya na hindi talaga tumataas temperature sa normal level. Question ko sir, ok lng ba yun ginawa ng mechanic? anung pros and cons kung sakali? Thanks again sir DD.
Btw, uuwi ako ng june para personal ko macheck yung pajero, dalhin ko jan sa inyo sa central diesel para through check and professional advice galing sa iyo.

Hindi okay tanggalin ang thermostat. Kung maayos ang thermostat at nagooverheat, may problema somewhere. Hindi tamang solusyon ito. Ang thermostat ay importante para mabilis na ma attain at mapanatili ang optimum operating temperature ng makina.

Ty sa reply sir. Hindi naman daw nag ooverheat, ayun sa mechanic para daw maiwasan overheat> Hindi rin pala tinanggal yung mismong thermostat, binutasan lng daw yung valve. Pansin ko nga puro remedyo ginawa ng mechanis sa ck ko, mahirap din kase wala ako sa pinas bayaw ko lng nag aasikaso. Ty sa info sir, first time ko kase mag diesel na sasakyan kaya nangangapa.

Mag o-overheat ang car pag tinanggal ang thermostat.

Sir dieseldude goodevening po.
Our car is a 2005 hyundai tucson crdi now at 70k kms. Last friday naputulan po kami ng timing belt. Pinalitan na po yung mga nasirang pyesa (4 intake cam followers at yung mga belt tsaka yung injector seals. Pinaltan narin yung air filter).
Today nagstart na po siya pero there is white smoke even at operating temp. Sabi po ng mechanic baka daw tinamaan din injectors. Ano po marerecommend niyo?

Sir Dieseldude,

Newbie here, I'm still back reading and I'm just at page 34. My Father died a month ago, he was the mechanic in our family, I don't know anything about cars, only in driving it. Due to his abrupt leaving, some problems with our Mitsubishi Adventure 99 model has remain unsolved. I hope you could give me some ideas so I could atleast get a better picture on what I am looking at before I go to a mechanic shop.

Hard starting even when engine is already hot. = already replaced glowplug
I have to atleast crank it 2 - 3 x before it starts.
Small white smoke coming out of the tail pipe when it starts, but none I can see when running
Battery was bought last Dec 2102, but I think it still is ok as it still can redondo the engine
Never overheated but almost once in 2010 the temp gauge has almost reach the H level, I immediately park it and let it cool down then add water to the radiator that has a leak. which had been repaired since. Now I am using coolant .
Ride is okay and still has "hatak power"
Mileage is at 180K kms.
Cleaned air filter with air compressor, filter was bought a year ago.
Already replaced fuel filter (OEM, followed your adviced).
Planning to have it change oil and replace oil filter by next month
I am going to try to add 2T oil in the fuel tank as an experiment, gotten from a thread on this site

I couldn't believe all the work and effort, pressure and cost my father has undergone in the maintenance of a vehicle

Thank you very much in advance

Check the glow plug relay. It will not energize your glow plugs if faulty.

Does white smoke deminish as engine reaches normal operating temp?

How much water did you have to add?

Ride is okay and still has "hatak power"
Mileage is at 180K kms. This is quite high.

Hindi yan dapat maputulan ng timing belt at 70k kms. First owner ka ba?

Pinalitan na po yung mga nasirang pyesa (4 intake cam followers at yung mga belt tsaka yung injector seals. Pinaltan narin yung air filter).
Today nagstart na po siya pero there is white smoke even at operating temp. Sabi po ng mechanic baka daw tinamaan din injectors. Ano po marerecommend niyo?
1) Check timing
2) Pull down and test injectors.
3) Kung walang makitang problem, pull down cylinder head to check for bent valves.

Sir where can you find the glow plug relay?

White smoke disappear and is replaced by black smoke

About 3 liters sir

Update: Sir Dieseldude, it seems I have solved my hard starting problem. It seems that when I had replaced my fuel filter, I did not bleed the air out. A friend of mine help me with the bleeding and after that no hard starting. Now its one click and it starts. My problem now is I am seeing black smoke.

check yung air suction-charging system: from air filter, hose connection, turbo charger, inter-cooler & egr. subukan mo paandarin na walang air filter, also baka need cleaning ang egr. Malaki hinala ko na problema ay sa sa supply air lang. I also have 1st gen tucson but only about 75K odometer reading. Never have problem like yours, the only time I seen black smoke was when the air hose in the turbo charger outlet was disconnected. I personally maintain the car though..

[Ivanator]

Ok I will have to check that sir weisshorn, tnx

Sir dd, i have a taxi, accent crdi. white smoke napo lumalabas sa pipe, sabi po ng mekanik ko, kelangan daw po pa-calibrate mga fuel injectors. Tama po ba? Ano po ba dapat ko gawin? Ung mga tinawagan ko po na shop, grabe po ang prices sa calibration. I badly need ur help and advise.
Bagong linis lang po egr,turbo at mga tambutso

Sir dd, i have a taxi, accent crdi. white smoke napo lumalabas sa pipe, sabi po ng mekanik ko, kelangan daw po pa-calibrate mga fuel injectors. Tama po ba? Sa experience ko, bihira panggalingan ng white smoke ang injectors. Pwede naman tanggalin at i-test ang injectors para makasigurado ka.

Ano po ba dapat ko gawin? Ung mga tinawagan ko po na shop, grabe po ang prices sa calibration. I badly need ur help and advise.
Bagong linis lang po egr,turbo at mga tambutso.

May tanong ako:
1) hard starting ba?
2) malakas ba ang blowby pag binukas mo ang oil filler cap?
3) Ok ba ang power?
4) kelan yung huling palit ng air and fuel filters?
5) Kelan ba nagsimula ang white smoke?

Sir DD, Good Day!

I recently got a 2006 Isuzu Alterra, 65k on odometer, 2nd hand from dealer. Changed oil, changed air and fuel filters. Power is good, consumption is ok. The problem: It emits a lot of white smoke (the kind that is nakakahiya) when getting up from stop to go on traffic lights, little to no smoke on idle. I bought it to Central Diesel and they performed diagnostics. Found no fault on their scanner. Mechanic floored the gas pedal and it exhausted a black cloud that overtime gradually reduced. I told him that I don't have problem with that kind of smoke, My problem is the white one that appears when in traffic and the signal lights.. told me that "maybe" I just need to tax the engine more cause its been idle for quite a long time (assuming cause of year 2006 with 65k mileage), baka may mga bara-bara lang na naipon" since it came from a dealer. I'm ok with that but, it really bugs me to see this white cloud of smoke when in traffic and upon going from a traffic sign... please help.

Question:
Upon reading this thread (up to page 90 pa lang eh), I found a similar post to what I'm experiencing and you replied this:

If we assume that your nozzles are good, try these:

1) Check injection pump timing

2) Check valve clearance

3) Check compression

4) Check injection pump

Aren't these parts checked by the diagnostic scanner? Am planning to go back to have these parts check.

This thread is the best resource I've found for troubleshooting diesel and pacifying troubled diesel owners like me....
THANKS FOR SHARING YOUR TIME and KNOWLEDGE!

Jake
