Dieseldude, I have toyota revo with a 2LII-T in it..Just wanna know if its possible to convert a 2l-t into a 2l-te?? or swap nlng sa 2l-te?

2LII-T na ba yung revo pagbili mo?

ito sir website nila...

Bale approved fuel enhancer sya.... Salamat sa information. Binisita ko na ang Bioactiv website. Mukhang ok naman ang produkto nila.
Pinatataas ko lang %blend ng biodiesel na kinakarga ko kaya naglalagay ako ng additive....
Thanks for the reply.
Pag balik ko sa pinas, mga October eh magpa check ako ng usok or compression test. Meron ba sa Isuzu Quezon Ave? or sa Inyo?
Mga magkano kaya yun sir? Wag mo na muna isipin ang compression test dahil model 2007 ang Sportivo mo. Batang bata pa yan. Siguradong maayos ang compression pressures mo. Btw, nasaan ka ba?

Nasa Russia ako ngayon sir./.....bali ang work ko dito eh 6 weeks nasa russia ako then 3 weeks eh nasa pinas naman ako for vacation.
Thank you ulit sa reply.

Mabuhay ka kabayan. Parang maganda yata ang work jan mo dahil pwede ka makapagbakasyon every 6 weeks.


Good luck, chaka ingat lang,

Dieseldude, tanong ko lang po. I had my 4 nozzles replaced and installed by Betan-Makati last month (my engine is 4M40) to correct the black smoke. After the installation, wala na ang smoke. However, ngayon mahirap magstart pajero ko kahit maiinit na ang engine (so i think not the glow plugs ang reason). What i did, I stepped on the gas pedal (maximum to the floor), with this, magstart na siya after few revolution of the starter motor (around 2-3 seconds). what do you think is the problem?


Possible problems are:

1. glow plugs or preheat system
2. weak battery if your cranking speed is low
3. air in your fuel susction lines
4. injection pump
5. low compression pressure

Btw, ano na ba ang mileage ng Pajero mo? Your engine needs glow plug assist even when hot if it's mileage is high due to normal wear on the piston rings and liners. High mileage = low compression pressure = low ignition temperature.

Start with 1, 2, & 3 before considering 4 & 5.

Good luck,

Dieseldude

Dieseldude * what was the common trouble of CRdi engine?

We have only serviced a few CRDIs as these engines are still quite new. So it is still quite early for me declare a common problem on the various systems.

But from my limited experience, I beleive that "water in fuel" is the killer, which affects the high pressure pump. It cannot deliver enough flow and pressure. Symtoms are no start, hard start, and hesitation after a gear shift.

By the way, do you have a common rail diesel? What's your make and model?

Yes it is possible. It fits perfectly as size is almost identical.

However, modification is not easy. You will have to get a good running 2LTE, complete with ECU, harnesses, throttle position sensor, fuse box, starting relay, etc.

If you lack the experience and know-how, I don't suggest you try it. The mechanical 2LT's power is sufficient for the Revo anyway.

Dieseldue, thank you for the reply.

Btw, ano na ba ang mileage ng Pajero mo? Your engine needs glow plug assist even when hot if it's mileage is high due to normal wear on the piston rings and liners. High mileage = low compression pressure = low ignition temperature.

Ang mileage ng Pajero ko is 80km. I wonder also, I have been replacing glow plugs every six months (starting last year) and mitsubishi parts pa, which cost 1.8k/pc. do you think something is wrong with the electrical, that's why the glow plugs got busted easily?

Last, how to check the battery if it needs replacement? kasi kaya pa nitong magstart. Many thanks for your help

Ang mileage ng Pajero ko is 80km. Your compression should still be fine at 80k kms, not unless your engine has experienced overheat condition/s.

I wonder also, I have been replacing glow plugs every six months (starting last year) and mitsubishi parts pa, which cost 1.8k/pc. Mahal talaga ang original Mits glowplugs, but they last long.


do you think something is wrong with the electrical, that's why the glow plugs got busted easily? Possibilities are:

1. You may be buying fake glow plugs.
2. Preheat system is defective, voltage is applied to the plugs on an extended duration.
3. Injection pump may be causing a hard start condition. Prolonged and repeated starts puts a heavy strain on the glow plugs as they are cycled and energized everytime you do a start.

Last, how to check the battery if it needs replacement? kasi kaya pa nitong magstart. Many thanks for your help. Low cranking speed is a good indicator of a weak battery if your starter, bat cables and terminals are in good condition. Motolite etc. can check your battery. You can also do a voltage drop test while cranking.

Do you experience hard start and hesitation during morning starts?

Dieseldude, thank you for the reply. You are really of help . Just an update, I removed the glow plugs last night, to my surprise 2 are not working and the other 2 are still fine.

Is there a possibility that location of the glow plugs matters? Of the two glow plugs that are still working, one is already +10months old, while the other one is still 3 months old (kasabay it sa pag-install sa other 2 busted glow plugs). I wonder why this +10 month old glow plug outlives the others? and its located in the 2nd cylinder (starting from the front). Does location matters? or the "new" glow plugs which are installed at the same time were just fake?

Preheat system is defective, voltage is applied to the plugs on an extended duration.

Ok, ill check with the preheat system. Tama kaya if i test the preheat system like this? Ill remove one glow plug (the one still working), attached to the wire leading to the glow plugs, and turn ON the keys (but not crank the engine). If the glow plugs remains glowing after the heater light turns off, therefore the preheat system is defective because it extended the duration of heating the glow plugs = short life of glow plugs?

Injection pump may be causing a hard start condition. Prolonged and repeated starts puts a heavy strain on the glow plugs as they are cycled and energized everytime you do a start.

Hopefully the injection pump is still working

Low cranking speed is a good indicator of a weak battery if your starter, bat cables and terminals are in good condition. Motolite etc. can check your battery. You can also do a voltage drop test while cranking.

Ok, ill do the drop test

Do you experience hard start and hesitation during morning starts?

I experienced hard starting in the morning and also in the afternoon. This morning what i did, before cranking, i stepped on the gas pedal to the floor + turn ON the keys twice (without cranking, just to extend the heating of the glow plugs ), and cranked. Once lang ang cranked ko (around 2 seconds) umanaadar kaagad ang engine with 2 hiccups (but I stepped the gas mid-way, so na wala na ang hiccup)

Many thanks again for the inputs.

No, cylinder location does not influence glow plug life.

or the "new" glow plugs which are installed at the same time were just fake? I'm not sure; but this is a possibility. Close inspection might answer your question.

No, this is not the way. The system may not even preheat if only one working glow plug is hooked up as it will see a wrong resistance value.

Injection pump may be causing a hard start condition. Prolonged and repeated starts puts a heavy strain on the glow plugs as they are cycled and energized everytime you do a start. Hopefully the injection pump is still working.

Once lang ang cranked ko (around 2 seconds) umanaadar kaagad ang engine with 2 hiccups (but I stepped the gas mid-way, so na wala na ang hiccup) Install 4 good plugs, and check if engine easily starts in the morning. If you still experience difficulty in morning starts, injection pump may have to be checked.


Many thanks again for the inputs. You are welcome...
