Diesel Fuel Injection System Help Desk

[Dieseldude]

Bosch yung pump ko. Bali na calibrate lang siya recently and marami parts na pinalitan. Nung andar ng engine after calibrate wala siyang knock pero wala naman power yung engine. Sabi nung mechanic eh ni retard niya timing ng injection pump pero napansin ko na nagkaroon ng knock na malakas. Dapat itama lang ang timing. Hindi na kelangan mag retard or advance.

Mukhang sa lahat ng cylinder yung knock at medyo low power pa rin at me marami black smoke during accelerating pero at idling wala naman smoke yung sedona. My sedona pala si automatic. Nag perform ba kayo ng injection timing sa shop nyo? Yes.... Baka may problema ang injectors.

Kasi pabalik balik na ako dun sa shop eh ang reason niya is engine na daw ang maingay. Thanks for the rapid reply sir... You're welcome......

Dapat ibaba na ang injection pump, palitan ng overhaul kit, tapos calibrate. Medyo matigas na ang rubber seals and gaskets ng pump mo. Available ang pump overhaul kit and some fast moving parts.

thanks sir sa reply. Kung sa shop ko po ninyo dalhin. magkano po kaya abutin ko. paki pm nlang po sa akin thanks.

Sir pa PM na lang yung price kung magkanu aabutin yung patingnan yung injection timing at kung bubuksan din ang mga injectors. Ty

hi !

I would like to ask what is the injector of 2006 strada pick up now? is it bosch or denso? The Strada DID has the Denso injectors on it.

how about the isuzu trooper 4jx1 turbo local made 2001? coz our tropper suffers lot of injector failure, it is replaced twice. huh These injectors are really a problem.... and nobody fixes them here properly. Population is too low to justify investing on expensive equipment to service these injectors. Isuzu should replace these free of charge.....

thanks You're welcome...

Ipinasok ko early today sa Toyota Cubao yung Innova ko for a 2nd opinion...

As much as possible I didn't share the diagnosis of Toyota Ortigas with them. Pero sa kuwento pa lang ng SA, supply pump agad ang duda nya... then possible din daw na injectors...

Ganoon ba talaga ka common ang issue na to for them to have it as top of mind na possible source of the issue?

Anyway, I am hoping na they would have a more solid basis for their diagnosis. Sinabihan pa ako na they will charge me something like 1,800 petot for the diagnostic... I will check my last PMS receipt kung may item dun na diagnostic for the complaint I had on the acceleration sa Ortigas...

Ipinasok ko early today sa Toyota Cubao yung Innova ko for a 2nd opinion... Good decision..

As much as possible I didn't share the diagnosis of Toyota Ortigas with them. Pero sa kuwento pa lang ng SA, supply pump agad ang duda nya... then possible din daw na injectors... btw, have you checked / replaced your air and fuel filters?

Ganoon ba talaga ka common ang issue na to for them to have it as top of mind na possible source of the issue? Yes, that's correct.

Anyway, I am hoping na they would have a more solid basis for their diagnosis. Their scan tool should be able to detect the fault. It would also be good if you are present when they perform the scan.

Sinabihan pa ako na they will charge me something like 1,800 petot for the diagnostic... This is fair....

I will check my last PMS receipt kung may item dun na diagnostic for the complaint I had on the acceleration sa Ortigas...

My advise:

1. Ask for a worst scenario estimate.
2. If the price is acceptable, request them to do the work one at a time, and not alltogether. This way, you will see the true correction.
3. If they say that the problem is due to a faulty supply pump and or injectors, tell them to first install a test pump. This is cheaper than injector replacement.
4. Lastly, make it clear to them that you will not pay for any installed part/s which did not correct your complaint.

Hi Dieseldude,

No idea. I don't have the air flow specs of both Toyota and K&N. In the absence of specs, you can't go wrong on original.

If the K&N air flow specs match or exceed Toyota's, and if your cost comparison is correct, K&N would be a good alternative....

Thanks..... You're welcome...

Dieseldude,

Many thanks. That is exactly what I'm looking at, the specs of the original against that of K&N.

On another topic, I'm a bit worried about these DENSO Common rail system failures. Do you have statistics (Year Model against Number of cases you have attended to). Will the possible defects result to a significant danger when driving? PM me please if the answer is sensitive.

dieseldude akala ko bosch ang CRDi ng strada, parang meron ako nabasa sa topgear magazine, anyway thanks,

so high risk din masira ang DId ng strada similar to D4d ng toyota?

[Dieseldude]

dieseldude akala ko bosch ang CRDi ng strada, parang meron ako nabasa sa topgear magazine, anyway thanks, DID uses Denso..... sure yan...

so high risk din masira ang DId ng strada similar to D4d ng toyota? We don't know. There may be a product improvement from Denso.

I got feedback from Toyota Cubao na on my Innova 2.5G D4D acceleration problem.. .

they recommended to change the ATF and change the fuel filter... which I think are reasonable naman so pina - go ko na.... although sa tingin ko lang, sa Toyota Ortigas dapat nabanggit na yun pero hindi eh...

anyway, they also recommend to bring down the fuel tank for inspection / cleaning - this I know will take more than 2 days so hold off muna...

They also suggested na ibaba yung EGR and injectors eventually para makita talaga.... ang weird... meaning kailangan ibaba para makita? so they are also guessing? They don't have test equipment to check kung within spec pa ba ang buga ng pump, buga ng injectors etc?

they recommended to change the ATF and change the fuel filter... which I think are reasonable naman so pina - go ko na.... although sa tingin ko lang, sa Toyota Ortigas dapat nabanggit na yun pero hindi eh... Correct. Those are the first things to check...... the air filter too.

anyway, they also recommend to bring down the fuel tank for inspection / cleaning - this I know will take more than 2 days so hold off muna... Do the above first. And if the problem is already corrected, they don't have to bring down the fuel tank.

They also suggested na ibaba yung EGR Again, if the problem is fixed, they don't have to touch the EGR.

and injectors eventually para makita talaga.... ang weird... meaning kailangan ibaba para makita? so they are also guessing? They don't have test equipment to check kung within spec pa ba ang buga ng pump, buga ng injectors etc? These are the most expensive things to replace. The only way to check these is to put in test pumps and injectors.

Like is said from the very beginning...... one at a time lang. Wag sabay sabay. You have to know what was really causing your problem... And it will be very costly if they do these work scopes altogethr.

Grand billing yan. Kawawa ka naman...

hello dieseldude...

I have another inquiry about engine oil nga lang part na rin ng engine un kaya sana hindi ito out of topic...tanong ko lang sana kung ano ba mas OK sa 2 ito Royal Purple or Motul? Any pro's and con's? Tsaka nagbebenta ba kayo ng ganyang products sa shop nyo? Tsaka ano ba yung nirerecommend nyo sa clients nyo pag nagpapachange oil sila..?

TIA ulet...

>hi' at 130kph normal lang ba na umusok ang innova 2.5 D4D...??? 20k na odo niya 11months old pa lang...''' ok' thanks...'

madami ako nkikitang mausok na 2.5 innova specially pag biglang tapak ang driver.

pero in my case sa strada wla ko nkitang smoke na mkikita mo sa side mirror while cruising 180 km/hr.

check mo sa casa, alam ko yan amg madalas na reklamo ng mga innova owners,

diseldude bkit yun hi ace d4d ng pinsan ko gingamit sa pamasada pero wlang usok, but yun innova same engine sila pero mausok yun iba at injector problem.

meron ba silang difference sa internal parts like injectors? thanks

[speed unlimited]

Tanong ko lang maraming mga sasakyan rito sa atin na kahit bago o lumang diesel na sasakyan ang mausok . Dahil ba sa quality ng diesel fuel o sakit na rin ng makina ng diesel dito sa atin .

Tsaka nagbebenta ba kayo ng ganyang products sa shop nyo? No.

Tsaka ano ba yung nirerecommend nyo sa clients nyo pag nagpapachange oil sila..? Sinusunod ko lang ang recommended oil grade sa owner's manual para walang mali. Never pa naman ako nakaroon ng engine lubrication problems.

TIA ulet...

[Dieseldude]

Tanong ko lang maraming mga sasakyan rito sa atin na kahit bago o lumang diesel na sasakyan ang mausok. Hindi naman mausok ang mga bagong sasakyan. Lahat nang diesel ay meroon usok. Kaya meron tayong smoke emission test. Ito ang tool na ginagamit para masukat kung pasado sa batas ang smoke level ng isang sasakyan.

Dahil ba sa quality ng diesel fuel o sakit na rin ng makina ng diesel dito sa atin... Hindi naman masama ang diesel natin, at hindi rin ito ang pinanggagalingan ng usok. Mausok ang sasakyan dahil sa poor maintenance.
