Diesel Fuel Injection System Help Desk

Ok naman yung switch, could having my injection pump checked help solve this?

Check the downshift cable. It may be out of adjustment.

You can also try the "transmissions" forum at Tsikot. You my get better inputs.

Sir DieselDude at fellow tsikoteers,

Ako naman ngayon ang nagkaproblema. My engine is 4D56T..kahapon lang e nagfflicker ung oil pressure light. kapag nirebolusyon e nawawala at kapag hindi inapakan ang accel pedal e nago-"on" ung warning light ng oil pressure. nangyari na ito dati last june 2009 i think but due to low oil levels.
Pero ngayon iba naman. ok naman ang oil level. i'm using delo gold 15W-30.
Last oct 2009 eto mga pinagawa ko:
1. change cyl head gasket
2. change valve seal
3. cyl head grinding
4. change oil and filter

Eto naman ang mga iniisip ko na checkpoints:
1. sending unit baka defective
2. due to oil leaks sa oil cooler lines (bka humihigop hangin kasi matagal ko nang hindi napagawa ung kaunting leaks)
3. worn engine bearings (crank and cam)
4. plugged oil filter? ewan ko lang kasi may bypass naman.
5. plugged oil filter? ewan ko rin.

Sa mga nakaexperience nito kindly share naman. it would be a great help at least i have some ideas bago ko ipaconfine ang pipip ko. thanks a lot mga sir!

Try using 15W-40. Mainit na ang panahon ngayon.

1. change cyl head gasket
2. change valve seal
3. cyl head grinding
4. change oil and filter

Eto naman ang mga iniisip ko na checkpoints:
1. sending unit baka defective
Temporarily remove sending unit, and put in a mechanical pressure guage to see the true oil pressure. If pressure is OK, replace the sending unit.
2. due to oil leaks sa oil cooler lines (bka humihigop hangin kasi matagal ko nang hindi napagawa ung kaunting leaks) Hindi pwede humigop ng hangin sa oil cooler dahil pressurized ito.
3. worn engine bearings (crank and cam) Possible cause ito ng low oil pressure. To confirm, you have to check the condition of the crank bearings, and measure bearing to crankshaft oil clearances.
4. plugged oil filter? ewan ko lang kasi may bypass naman.
5. plugged oil filter? ewan ko rin. Hindi siguro pwede ito dahil nabanggit mo na kapapalit mo lang ng oil filter.

Sa mga nakaexperience nito kindly share naman. it would be a great help at least i have some ideas bago ko ipaconfine ang pipip ko. thanks a lot mga sir!

Salamat sir dieseldude sa reply esp. sa #2 item. nga pala i forgot that i was using delo gold monograde sae 40 pala. last year pa yung 15w-30. my problem is finding a mechanic with complete tools esp ung mechanical oil pressure gage. i'm praying na hindi pa sana pudpod ang mga main bearings. ...

sir diesel dude, I just bought a 95' mitsu pajero JDM(surplus) with a 4m40 2.8li engine, A/T tranny, and 4wd. I really dont have any problems with my rig. Yung fuel consumption lang, I only get 6km/li on city driving. Is that normal? or do I need to have it calibrated?
exhaust is ok, no black or gray or white smoke. Tires are all stock

6km/L * city is quite high. Check your air intake system, etc.

City driving cannot be an accurate indication of fuel consumption due to many variables. Try hi-way driving.

DieselDude,

Hey got my bighorn fixed, yep had the cable fixed too and now it runs fine. Thank bro

[blue_gambit]

If I decide to have it recalibrated, how much will it cost me kaya? thanks

sir: need your opinion... may problema ang vacuum system ng 97 hlander ko... noticed na mataas ang idling... had it checked by a mechanic... ang sabi: wala daw suction yun hose connected sa alternator... baka daw barado... ok pa naman ang electrical system ko... di ko alam na may connection sa alternator ang vacuum system ng engine ko... sorry, newbie sa diesel engine kasi...na rerepair pa ba ito? thank you very much!!

sir: need your opinion... may problema ang vacuum system ng 97 hlander ko... noticed na mataas ang idling... had it checked by a mechanic... ang sabi: wala daw suction yun hose connected sa alternator... baka daw barado... Baka may butas ang hose,or collapsed ang hose, or bake mahina na ang vacuum pump?

ok pa naman ang electrical system ko... di ko alam na may connection sa alternator ang vacuum system ng engine ko... Vee belt ang pumipihit ng alternator. Alternator naman ang nag da-drive ng vacuum pump. Nakakabit ang vacuum pump sa likod ng altrernator. Pwedeng paghiwalayin sila para ma-check ang vacuum pump.

sorry, newbie sa diesel engine kasi... No problem, ok lang yan.

na rerepair pa ba ito? Shempre naman. Kaya dapat ng mechanic mo yan. thank you very much!!

hi dieseldude. please pm me where your shop is located. i plan to pay a visit when the time comes i need help on my engine. i have innova 2010 d4d.

Sorry, this is not my line.

Hi Dieseldude,,,

Another question...

Yung mga parts kagaya ng oil filter, fuel filter etc na nabibili sa mga auto supply e original din kaya..? Kayo saan ba kayo bumibili ng mga parts na kagaya nito (casa o auto supply)? Balak ko na kasi magpalit ng fuel filter e pinag-iisipan ko kung sa casa o auto supply ako bibili pati na rin yung oil filter...

TIA po ulet...

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

Engine or timing malamang ang dahilan dahil lumabas ang problem after the overhaul, at hindi mo naman pinagalaw ang injection pump..

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. Hindi ako sure sa required nozzle opening pressure. Baka kaya i feel loosing power. Hindi ito ang cause ng low power.

Applicable ba sa lahat ng makina yung 10 deg at top dead center ang injection pump timing. Hindi. Medyo confuse lang po kasi meron din po ako nabasa nga dito sa thread na before top dead center. Ang timing specs ay nasa workshop manual ng engine mo.

Ano ba ang make and part number ng injection pump and injectors mo?

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