Diesel Calibration: Central Diesel vs Betan Technique

[jacorb_88]

Pajero 4M40

I went to Central Diesel this weekend and to Betan Technique this morning.This is the most objective I could possibly present their diagnostic service.

Central Diesel (QC Ave)
Mechanic: Hard-starting ho?
Me: There was a time ho na nag-hard-start sya after several days layoff. Nag-hard-start, then palyado, mausok, after few seconds namatay. 2 times na nag-ganon. Pero nung nag-start na sya, okay na sya.
<Started Pajero, popped the hood, accelerated, big cloud of black smoke>
Mechanic: Kelangan i-calibrate pump, tapos palitan din ang nozzel tips.

Betan Technique (Makati)
Mechanic: Ano hong problema?
Me: There was a time ho na nag-hard-start sya after several days layoff. Nag-hard-start, then palyado, mausok, after few seconds namatay. 2 times na nag-ganon. Pero nung nag-start na sya, okay na sya.
Mechanic: Pero kamusta naman ho nung nag-start na sya? Nag-hard-starting pa ho ba?
Me: Hindi na naman. Okay na naman.
Mechanic: Kamusta ho power?
Me: Okay naman. Hindi mo naman mapapansin or masasabi na nag-loss of power na.
Mechanic: Meron lang ho hangin na nag-buildup dahil sa ilang araw na hindi nagamit. Tapos ho sabi nyo naman okay pa naman power. So, hindi naman ho kelangan ayusin pa ang pump.
Me: At saka mausok din. Pa-check kung ano kelangan gawin.
<Started Pajero, popped the hood, accelerated, big cloud of black smoke>
<Removed air-filter, accelerated again, big cloud of black smoke again>
<Removed oil level and oil filler cap to check leaks and blow-by. Seems okay.>
<Removed hose from turbo, accelerated again, no black smoke>
Mechanic: Sir, ito ho ang problema. Kelangan nyo muna paayos ang turbo nyo kasi yung turbo nagdadala ng langis at sumasama sa combustion kaya maitim ang usok. Hindi ho natin pwedeng palitan agad ang nozzle tips nyo kasi ho pag may kasamang langis eh uusok talaga, kahit palitan pa natin ang tips. Kaya ho, paayos nyo muna turbo then balik ho kayo dito para check natin condition. Palitan na rin ho natin ang air filter and fuel filter.

I would like to think that both of them could do calibration service at par with each other, but based on the above, one could really see the kind of service each of them provides to their customers.

Mabilis pala sa Central eh...........saan? kahit ako if ever kailanganin ko Denso or Betan

Napa check mo na ba turbo mo, what is the diagnosis?.

You could really see the kind of service each of them provides to their customers after you have verified the diagnosis.

Pero maganda experience mo kasi masasabi natin na wala pa checklist na ginawa si dieseldude
para sa mechanics nya. This is something he should look into to provide a better failure analysis procedure. Kailangan kasi i standardize nya para kahit sino naka duty sa
tindahan ay pare pareho ang service na makukuha ng mga customers.

Ang tawag namin dito ay "SHOWTIME".

And to the mechanic who provided you the diagnosis dapat i post mo pangalan nya para me
recall. He could be a promising young star, eventually he would want to run his own
independent shop. Atleast kilala na natin sya. Pero I find the filter change uncalled for.
Meron siya "showtime" and I like it. It all add to the service you know.

Sir balitaan ninyo po kami on what happened.
What is your mileage?
Central Diesel repairs injection pumps, injectors and turbos.
If turbo ang problema then Central Diesel should have given its recommendation.

make sure that the turbo is really leaking oil.. most of the time the oil coming from the turbo is the oil mist from the PCV.. sometimes due to intense turbo boost, it can suck oil mist from the pcv, the oil then collects in your intercooler then to your intake resulting to black smoke...

have your intake, turbo intercooler and exhaust cleaned

Sir 4M40 black smoke at hindi white smoke?
Mileage?

Sir Jacorb did you post this on 08-01-2006?

"arl0011,

i had my ride serviced at betan. initially, they replaced nozzle tips then there was still black smoke emitting. Then they calibrated injection pump. That's it, no more black smoke. As for the black smoke during sudden acceleration, it is a bit normal for diesel as I learned. Betan meant not to cripple your pockets by changing everything at once. If it can be 'treated' by administering the first level fix, then good, it will not cost you an arm and leg. But if it still so requires for second level fix, that is, injection calibration, no choice but to do it. That's how they normally address the problem in major contrast to most shops.

Recently, I had my ride checked due to high consumption plus there was smell of diesel all over. The calibration shop assessed that they need to replace repair kit due to leak. I brought it to Betan to have the repair kit replaced. And guess what, the same statement they made during my first visit at Betan, they need to look at the problem and see if there is really a need to replace the repair kit. Cost me 200 pesos for the leak due to washer, that would have been 6,000 to another calibration shop which gave me the first prognosis."

Maybe this is the reason they are suspecting the turbo. Sila kasi gumawa ng pump at hindi Central Diesel.

Dalhin mo sa Kia or sa Delphi Diesel service workshop yan. Delphi ang common rail system ng 2002 Carnival. Lalaki lang ang problem mo kung susubukan gawin ng mechanic na kulang sa hustong training.
