Thanks po ulit...

Nasa tabi ng injection pump and dataplate.... makikita mo jan ang make and part number.

Sa casa ko kinukuha ang filters para sa "modern diesel" ko. Sa Banawe ako bumibili ng filters para sa mga lumang sasakyan ko. Hehehe.

OIC..malaki ba talaga yung pinagkaiba ng fuel and oil filter sa casa at sa mga nabibili sa auto supply? Sa mga auto supply kasi nakalagay rin na toyota, mitsubishi etc...so peke ba ang mga yun pag sa auto supply lang bibili?

*Dieseldude.

sir have you heard/read of the 2T oil added into diesel fuel? may mga presentation na (scientifically daw) tested and it improves lubrication, etc. etc.

I was wondering dahil kung makakatulong why not? kung placebo naman, sayang ang pera pero unti lang naman. Parang 1/2L to a tank or mga 65 pesos e 1/2 liter diesel mga 15++ pesos na so mga 50 pesos a tank nasayang.

ang kinatatakutan ko po e yung baka may madamage from injectors, fuel pump at catalytic converter (actually di ko alam kung meron ride ko. noob po. plus 2nd hand).

what do you suggestion sir?

TIA

Sir Dieseldude,

Yung knowledge ko po sa diesel engine eh dito ko lang binabasa sa thread. And its very useful.

Need your advice, first time ko magpapacalibrate and newbie sa diesel engine ang ride ko po is kia besta van r2 2.2.

Before nga po pala bago ko magdecide to calibrate I replaced the fuel filter and air filter and clean the exhaust pipe. I just don't know the original/oem kasi 2nd hand ko lang sya nabili. Presents of black smoke and lack of power is still present. Nangyari po pala siya after ng top overhaull ko.

Tanong ko lang po kung ano po yung nozzle pressure? napalinis ko na po sya at naka set sa 100 bars. Me nabasa po kasi sa ibang thread na for r2/rf engine 140 bars po tung nakaset kay sir duskylim po ata yun. Baka kaya i feel loosing power. Applicable bo sa lahat ng makina yung 10 deg at top dead center ang injection pump timing. Medyo confuse lang po kasi meron din po ako nabasa nga dito sa thread na before top dead center.

Location ko nga po pala eh Sto. Tomas Bats. Medyo malayo po kayo samin kaya advice na lang po..

more power and thanks po in advance,
jon2

My Dear Sir jon2:

Just to clear things up, I did not at any time specifically say or mention the design opening pressure of the RF diesel nozzles - as I don't know them myself.

I believe you were referring to an old post of mine where I pointed out that OLDER diesel engines with Indirect Injection systems (like mine) generally operate at lower injection pressures than the NEW common-rail designs.

I hope this clears up any misunderstanding.

I do NOT propose to give advice on subjects on which I do not have knowledge or experience, nor do I presume to second guess professional calibrators like Sir Jake.

Sincerely,

Dusky Lim

papano malalaman kung may katok ang diesel engine? sadya kasing maingay at hindi ko masabi kung alin dun yung katok kung meron man.

[Dieseldude]

OIC..malaki ba talaga yung pinagkaiba ng fuel and oil filter sa casa at sa mga nabibili sa auto supply? Walang pagkakaiba kung pareho ang binebenta ng casa at auto supply. Malaki ang pagkakaiba ng genuine at fake.

Sa mga auto supply kasi nakalagay rin na toyota, mitsubishi etc...so peke ba ang mga yun pag sa auto supply lang bibili? Hind natin alam kung fake ang binebenta ng mga auto supply. Makikita mo ang pagkakaiba nila kung mapagtatabi mo sila..... mula sa packaging hanggan sa actual part.

Dieseldude.

sir have you heard/read of the 2T oil added into diesel fuel? may mga presentation na (scientifically daw) tested and it improves lubrication, etc. etc. Never heard of adding 2T oil. I've heard of large truck fleets in the US who had been adding up to 4% used oil to their saddle tanks for years with no problems at all. This was during the mid 80s.

I was wondering dahil kung makakatulong why not? kung placebo naman, sayang ang pera pero unti lang naman. Parang 1/2L to a tank or mga 65 pesos e 1/2 liter diesel mga 15++ pesos na so mga 50 pesos a tank nasayang.

ang kinatatakutan ko po e yung baka may madamage from injectors, fuel pump at catalytic converter (actually di ko alam kung meron ride ko. noob po. plus 2nd hand). Sa palagay ko, hindi naman madadamage ang old style pumps and injectors. Pero hindi ko ito gagawin sa modern CR diesels.... baka mawala pa sa warranty.

what do you suggestion sir? Ingat lang tayo lahat. When in doubt, don't.

[Dieseldude]

papano malalaman kung may katok ang diesel engine? sadya kasing maingay at hindi ko masabi kung alin dun yung katok kung meron man.

Ano ba ang ibig mong sabihin "katok"? May tunog katok naman talaga ang mga diesels. Luwagan mo isa isa ang high pressure line papunta sa injectors hanggan mawala ang knocking sound.

Doowan is ok. Bad number yung nakuha mo.

Sir ask ko lang yun engine ko 4d56 pag start sa morning it produces white smoke ng sandli. pero recently nabalian ako ng glow plug while removing it so tinangal ang cylinder head para imachine shop to remove the broken glow plug tinangal ng shop yun isang injector and tinangal niya yata from the middle muna bago dun sa nakakabit sa cylinder head and nun inassemble na lahat jerky and shaking yun engine. when check sa lahat ng tinangal na part napansin kasi mechanic na may kulang na isang small part sa loob ng injector nung ibinalik na yun head from the shop. then kumuha siya from an old injector yun part na nawala. so when the mechanic put it back and lahat back to the car pagstart sa umaga the engine shakes and produces white smoke pero pag init na wala na and the shaking stops also. whats the problem kaya? and ano gingawa if loss compression ang engine? Thanks

Thanks for the info.

Calibrate injectors, check cylinder head torque, test engine compression.

and ano gingawa if loss compression ang engine? Replace pistons, rings, and cylinder sleeves.

Thanks. You're welcome.

Ano ba ang ibig mong sabihin "katok"? May tunog katok naman talaga ang mga diesels.

yung engine knock or "pinging", sir. naninibago pa ako sa diesel ko (pregio 97, 100k+ mileage). sabi naman ng mga mekaniko ganun daw talaga, maingay at mabagal sa arangkada. sanay ako sa compact cars na gas fed.

Luwagan mo isa isa ang high pressure line papunta sa injectors hanggan mawala ang knocking sound.

may mali kaya na nagawa yung mekaniko? after reading this entire thread last month, pina linis ko yung injectors tsaka tune-up, nabawasan yung usok. hindi nila ni-recommend na ipa-calibrate ko agad, tignan ko daw muna kung may major problem. wala naman sa tingin ko, or baka hindi ko lang alam kung papano makita yun problem.


salamat sir.

Ok na yan kung masaya ka na sa hatak at konsumo ng diesel.


salamat sir.

hello sir dieseldude...sir tanong ko lang if ever na mababa ang CO2 reading sa emission test does it mean na walang problem ang engine (loose compression) or injection pump ng car?Mine is a 05 Crosswind XT at nag log na siya ng 173Kms but the reading for CO2 is 0.29 compared to max allowable of 2.5.thanks po dieseldude and more power...

[Dieseldude]

hello sir dieseldude...sir tanong ko lang if ever na mababa ang CO2 reading sa emission test does it mean na walang problem ang engine (loose compression) or injection pump ng car? Hindi ko alam kung may direct correlation and CO2 reading sa engine and/or injection pump condition.

Mine is a 05 Crosswind XT at nag log na siya ng 173Kms but the reading for CO2 is 0.29 compared to max allowable of 2.5.thanks po dieseldude and more power...You cannot compare these. CO2 is a measurement of discharged carbon dioxide gasses. 2.5 is the K value for maximum allowable opacity (darkness) of a naturally aspirated diesel engine's exhaust.

I'm not sure if this has anything to do with the fuel system but it might. On my diesel Adventure, the accelerator pedal vibrates when speed is approaching 80KmH. This occurs at around 2K RPM but only happens in 4th and 5th gear. Reaching 2K RPM on lower gears does not produce the same vibration. Only the pedal vibrates. Not the steering wheel and definitely not the whole vehicle.

Check engine / transmission supports, wheel balance / alignment.

Will do sir. Thanks.
