Diesel Fuel Injection System Help Desk

[Dieseldude]

I have a starex 2k model TCI engine. 6months ago i had my injector nozzle tip replaced at bosch banawe nozzle tip is bosch 130. Previous Fuel consumption before the replacement was around 7.5km/li but my ride was a bit sluggish. After tip replacement, the FC now is 6 to 6.5km/li but the power improved. I still feel that the FC is far from the average as some other starex of same engine and model even lower have an average of 7 to 8km/li. Should i have my injection pump recalibrated? FC is influenced by a lot of conditions: eg. road & driving conditions, average number of passengers, aircon temp setting, fuel injection pump settings, etc..... Your injection pump can be tested to verify if it's settings conform to specs, and/or adjusted as necessary.

My other concern though this is not bout fuel system but i would appreciate if you can advice me though, is that on highway when i reach around 85kph my tranny locks at override and its suppose to stay locked at that speed or above. The problem is i need to keep a press on the pedal to keep my tranny locked. IF i relax a bit on the pedal, it downshifts and the rpm increases indicating a downshift in gear. What do you think should i do? This is the first time I've heard of such problem. So I don't have an answer at the moment. But I can study this and ask around.

By the way, is your injection pump electronically controlled?

Hi Iceman,

Can't post a fix for your tranny problem. Haven't had the opportunity to check on this issue. And I'll be away for a while on diesel training.

I'll post you if something comes up.

Try to ask an opinion from your nearest dealer.

Bye

Hey,
My EX12D 4 cyl diesel Honda generator injector pump is leaking fuel from the deliver valve holder or (outlet ports).
Can I remove these without causing any damage or decalibration?
There is a plate with 2 bolts that appears to hold each one down but they are 5 point heads (pentagon)and will require a special tool.
The outlet ports are steel and the pump housing is aluminum, I'm wondering if the threads are corroded?
Thanks for your time.

I believe you can remove the hexagonal delivery valve holder to replace the seals.

These screws are specifically made to tamperproof the pump. I don't recommend that you loosen these as pump calibration will be affected.

The outlet ports are steel and the pump housing is aluminum, I'm wondering if the threads are corroded? This is possible. But limit your checking to the DV holder only. Your leakage problem will probably be corrected.

Thanks for your time. You're welcome.

Dieseldude need your expert advice about my subic pajero 4m40.

1. Ang lakas sa oil almost 1 liter every week. Wala naman leak.
2. Hard starting sa morning and everytime na i park siya, kailangan i pump yung fuel para mag start. Sometimes maraming beses pa rin na try bago mag start, kahit pump mo pa yung diesel.
3. Laging namamtayan ng makina kahit nasa rekta, then pump muna ulit bago mag start.
4. Eratic Idling
5. Nung last cleaning ng fuel lines and fuel tank pansin namin na madumi parang may halong langis yung tank.
6.As of my last reading 4.9 km/liter fuel consumption ko.

I'm from Tacloban City leyte if ever pwede ko ba padala jan yung injector kung kailangan ng i calibrate then ship niyo nalang ulit pag nagawa na? How much po charge niyo estimate para maayos ko yung budget? Ilang days po matapos?
TIA

Subic 4M40s come in two injection pump versions, regular rotary mechanical pump or elctronic COVEC F pump. Which one do you have?

Your complaints seem to indicate an injection pump failure. But first check your glow plugs and glow plug relay. If these are ok, your injection pump may be faulty.

Rough estimate is 6 to 9k for the injection pump. Work duration is 1 to 2 days.

My mechanic suggested to do a top overhaul first to check the oil leak he suspects that the valve seal is the culprit since wala naman ibang leak sa engine. I ask him also to change all the fuel line hose, check the egr, change the air element and fuel filter to oem.

Sir affected din ba shifting ng AT from first to second gear pag cold pa yung engine pag faulty yung fuel injector? I'm experiencing this every morning pero pag normal temp na yung engine wala naman problema shifting, yung first to 2nd gear lang talga problema sa umaga.

I ask him also to change all the fuel line hose, check the egr, change the air element and fuel filter to oem. 4M40 injection pump is gear driven (no timing belts or chains). Lube oil could be pulled in from the pump's drive end if the drive shaft, oil seal, and/or bushings are worn out. Oil sucked in by the injection pump will return flow to the fuel tank. Result is a dark and thick appearance of diesel fuel due to oil contamination, and seemingly high oil consumption.... These were your initial complaints on your previous post...

I'm experiencing this every morning pero pag normal temp na yung engine wala naman problema shifting, yung first to 2nd gear lang talga problema sa umaga. I do not see how a faulty injector/s will affect transmission shifting when cold.... There is just no connection..

So even if we do the top overhaul the problem with the injectors sucking air will still continue? and the fuel tank will still be contaminated with oil?

So its a different problem all together, nyikes.

I'll update you sir on the developments though I believe the injectors still needs to be shipped to central diesel for evaluation.

This is very possible as your previous post seems to indicate an injection pump problem. You also first have to differentiate between the injection pump and the injectors.


So its a different problem all together, nyikes. I believe so.... my advise is based on your post. You can however opt to take your mechanic's position. He may be in a better position to analyze your problem as your car is with him.

I'll update you sir on the developments though I believe the injectors still needs to be shipped to central diesel for evaluation. Your injection pump may have to be serviced, not your injectors.

Good luck.

sir dieseldude, hope u can help me out on this one..

posted it also on kia carnival thread...

guys, gud pm...baka pwede nyo ako matulungan ulit..

just this afternoon nung paalis n kami sa parking lot ng walter mart munoz

nung nag start na ako ng carnival, ung rpm ko biglang umakyat, nag rev mag isa....so i decided to switch the key off...dami tuloy usok sa labas ng parking....anyways, inulit ko ulit, start again, same result, rpm would shoot up....so patay ko ulit susi...then i decided to check the throttle cable, pero ok naman sya at walang slack....tama lang ang kabit....i also check my gas pedal, wala naman ako nakita problema....ilang beses din ako nag try mag start pero same result.....rpm would shoot up..basta umabot na ng around
2.5k rpm pinapatay ko na makina....i was in the parking lot for almost 3hrs...hassle

so nag pa tow na lang ako.....then malapit na ako sa circle, i decided to "kadyot" the car.habang naka tow....(taxi lang pala ang nag tow sa akin).....saying to myself, what the heck try ko paabutin hanggang dulo ung rpm....dahil bwiset na bwiset na ako.......

so i "kadyot" the car...then rpm went up.....1.5k....2k...3k then around 5k rpm...the needle went down and it returned to normal condition.......so i told the taxi to pull over...so ayun normal na ulit...

then dito na sa house....i turned it off, then start again...normal na naman sya.....

guys long story pero, ano kaya cause nito..baka pwede nyo ako matulungan mag detect kung ano problem......hay gastos na naman

tnx guys






na post ko lang dahil nag ask ako sa friend ko kung ano ang possible na sira, though di nya kabisado ang diesel engines also ang carnival, he mentioned something about a "governor"?

then i search it and this thread came up.....meron ba nito ang kia carnival?

BTW: ride is '00 kia carnival diesel..

tnx

nung nag start na ako ng carnival, ung rpm ko biglang umakyat, nag rev mag isa....so i decided to switch the key off...dami tuloy usok sa labas ng parking.... Kung medyo maputi ang usok nung mag-wild, malamang lube oil yan... Baka nasobrahan ang karga ng engine oil.

anyways, inulit ko ulit, start again, same result, rpm would shoot up....so patay ko ulit susi...then i decided to check the throttle cable, pero ok naman sya at walang slack....tama lang ang kabit....i also check my gas pedal, wala naman ako nakita problema....ilang beses din ako nag try mag start pero same result.....rpm would shoot up..basta umabot na ng around

sir until now ok naman ang pag start..di na ulit nag wi wild..pero katakot pa rin kasi baka pag nasa parking or other place ulit eh baka mangyari nanaman...
how do i clean the intercooler? pwede ba ito basain at sabunin? tnx



lastly, sir dieseldude...san po located ang "governor" ng kia carnival?
many many many tnx po sainyo...

sana maraming pang taong katulad nyo na nakakatulong sa amin.....

also: do u have a shop? tnx
