normally, what you should do is to just have a regular tune-up. change plugs, oil, tapos i normalize yung timing. a 4 year old car will not do bad..
secondary thing that you may do is to ask your gasoline station guy who does the carwash to spray water into your muffler pipe while THE ENGINE IS RUNNING, tapos to rev your engine up para ma-expel yung tubig sa loob ng muffler. Do it around three to four times to ensure yung carbon build-up sa loob ng tambutso eh matanggal.
i have a friend who failed the emission test three times, tapos pag dinadala nya sa Honda Casa, eh sinasabi na wala namang daw problem, so it cost him money pa. ang naging problem pala is yung emission test machine eh hindi caliberated. so hindi porke casa maintained yung sasakyan, means, makakapasa sa emission test.
as i stated above, just get a regular tune-up and yung suggestion # 2 ko and everything else will be ok.
p.s. that is what i have been doing for the past two years.... ;)
What you can do is avoid cramming, emmission certificates have 60 days validity from date of issue. Have it tested over two different testing centers. Other equiptments are not calibrated daily.
1. Tune-up; air filter clean, spark plug clean, change oil.
2. There are numerous shops all over the metro. Even gas service stations do it for a fee.
3. Dipende po yan sa mga aayusin o papalitang piyesa.
Pag nag-adjust kayo ng timing before testing and reverting it back to norm after, ganun din ang risk na pollutant ang sasakyan. Why cheat over a Php300 test when you can help preserve our environment?
another way is to buy your comprehensive insurance from someone who will take care of the registration and emissions testing for you.
yes, i know it is cheating. and sometimes i get so pissed off seeing smoke-belchers on the road when i realize that the reason they are still on the road is the same reason i'm beside them -- cheating on the emissions test (not that my car is a smoke belcher, it's clean)
anyway, both me and a friend of mine had good experiences at Toyota Pasong Tamo. 893-8084 or 893-8453 and look for Mark.
my 10-year old car cost about 8,600 to insure (250k coverage) plus i paid around 1,000 more for the registration assistance and emissions testing. i faxed Toyota my OR/CR and that was that. their messenger dropped by 2 weeks later to give me my stickers and new OR.
best is to have your emmision test done at a "casa" of the same brand as your car. pag mitsu car mo, punta ka sa testing center ng mitsu (sa santolan). pag honda, nissan o toyota, punta ka sa testing center ng honda, nisan o toyota. at least pag bagsak ka they will know what to adjust, or fix.
saka ang emmision test naman pag bagsak sa una e free yung re-test.

That is a very bad idea. Water can get into your catalytic converter and mess it up.
If you fail emissions there can be many reasons but carbon buildup in your muffler is not it.
1 A tune up is the first and cheapest solution.
2 you can have a bad catalytic conveter. If your exhaust gasses smell like sulfur, its probably your cat conv.
3 you can have a blown or a pinhole in your headgasket. this is expensive to fix. you can tell if your exhaust gasses are very white. this means that water or coolant is mixing with oil.
4 your car can be burning oil- normally blue somoke. this means you need an engine re build.
If you have a 2000 and your car has gotten scheduled maintainance, you should have no problem.
With newer cars. that Run OBDII ECUs they dont even need to test the exhaust gasses with their machines. they just plug in to your cars serial port. your car has the ability to run an emissions test through its MAF and O2 sensores. The ECU just sends a report is everything is ok. Normally you know you wont pass emissions ahead of time cause your car's CEL will light up.
peterock17:::Very few and I mean very few cars here in the P.I have catalytic converters. I guess it's because of the low quality fuel we have here. There are accredited emission tester that are usually quite near an LTO branch. They usually test the emission of a vehicle from it's exhaust pipes.
di naman kaya yun equipment ang kelangan i-calibrate? i mean kung ganun kadami usok na pumapasok dun everyday, dapat at least once a day eh nililinis or calibrated dapat yun equipments... saka yun human factor na din.. kung pano tumapak yun tetster sa gas pedal.. baka naman biglaan....
What's cheating again? I must have missed something on the previous posts.
I just had my car tested in January, but unfortunately failed the test. The person who was doing the testing told me to step on the gas to make it pass and it did. (Hindi ako naglagay...) I guess you can say I'm guilty :whoa: for cheating on my emissions test. Although, I had made up for it by immediately taking the car and had the filter changed, cleaned throttle, changed oil, changed spark plugs, and changed coolant.
I had been doing regular tune ups before and don't know why I failed the test (and miserably), although I never encountered any problems and the car shop tells me there's nothing wrong with the car. :confused:

catalytic converters, imho, cars here are not equipped with one...

baka diesel nasa isisp mo sir afrasay. lahat na yata ng gasoline cars na lumalabas ngayon may catalytic converter na. ever since nag-take effect yung clean air act mandated na lahat ng car manufacturers na lahat ng brand new cars ay equiped na with cat.

hmmm... D*mn too much diesel in my system. :D But then again there are still a greater number of pre clean air act cars on the road.
