sir how much would it cost to have my injectors checked out at your shop? i just want the proper opening pressure back to original specs.. and by the way how much would it also cost to replace the springs inside the injector assembly.. thank sir..

What is your car / engine?

Are you experiencing any engine performance problems?

have a 01 TCI starex with the D4BH engine. i just feel like its lost some of the power that it used to have,, the thing was for about 3 weeks i had a 112 nozzle tip, i noticed the engine was nosier than normal..and it could only go 120kmph.. while benching lots of black smoke.. i then had them replace the nozzle tips to the original 130. which feels slightly better.....

wrong post

Sir Dieseldude,

Hindi naman sya nagoverheat normal temp lang naman from 1/4 to almost 1/2 ang play sa gauge ko. Siguro magpapacompression test na lang muna ako to make sure na yon yung problem ko, saan po kaya meron may services ng compression test? expensive po ba yon and gaano katagal sya ginagawa?

Many thanks sir for the advice, dami ako natutunan about my ride.

Gundamwing,

Any Isuzu service dealer should be able to do a compression test.
Call up the service department and ask how much it will cost.

yes i have sir...

Check injection pump to engine timing.

Hi Dieseldude,

I just wanted to ask if the aircon "idle up" mechanism for the Pajero 4M40 is indeed in the fuel pump? Also, can this be adjusted easily?

Many thanks! You're doing everyone a great service.

You're welcome.

You are correct. Idle-up device is mounted on the pump, near the throttle lever, and easy to adjust. It is vacuum-driven through a 12v solenoid valve.

[SIZE=5]My Diesel helpdesk has just been transferred to the workshop forum. This seems to be a good site. [/SIZE]

[SIZE=5]So keep those questions coming.[/SIZE]

[SIZE=5]Ask ko lang? Where would you prefer to see my thread? Survey lang. I don't mind the move they made, unless you do.[/SIZE]

A sticky would be great

Oo nga sana malagay sa sticky si sir Jake. Idol ko talaga kayo (sipsip aside)
O.T. Sana ma invite sa christmas party ng tsikot ang band ni sir Jake for an honest to goodness old school music.

By the way, what is sticky. I don't know this term.

And how did you come to know that I have a band?

[diesoline]

jake, when this thread becomes a sticky, it will always be on top of the thread list on the subforum where it is located. irregardless of the date of the last post.

thanks, by the way, for attending to my brother-in-law personally the other day.

idol! may banda ka pala!

Tama sir, it will never go down and will always stick on the top threads.

When i pass by Diesel Central and sometimes you where not there they tell me may tugtog si sir. Friend din po ng kapatid ko and anak ninyo, there both from U.P.

keep up the good work sir, more power to the business and the band.

I have been viewing some posts on ECU remapping and system modifications to increase power and improve engine performance.

I would like to caution you about these things, as these tend to deviate from the engine manufacturers' specifications. Engine performance may improve, at the cost of shortening engine life.

An engine's ECU and/or fuel system adjustments are set by the factory. These settings ensure optimal power & performance, proper emission levels, as well as extended engine life.

Extracting more power from a stock engine is easy, as these basically mean adding more fuel and air, etc. But will your engine last long under these modified conditions?

Careful!!!

Will sticky this.

S'Dieseldude, by stickying, this thread is perpetually on top of the thread list.

[4JGtootsie]

At last, we don't have to look for this thread down the line.
Thank you sir Pajerokid. Good work Mbiege.
keep up the good advice sir Jake.

Thanks Jake, 4JGtootsie and Pajerokid, we need to keep dieseling :-)
