humina yata ang engine ko?

[boybi]

dati i can easily reach 160-165kph, ngayon from 140-150, hirap na. pag dating ng 150, ayaw ng umakyat.
also, when overtaking, medyo mabagal na. i always have to downshift, hindi kagaya dati, kahit hindi ako mag downshift, swabe ang pagovertake.
kaka change oil ko lang, changed fuel filters, changed coolants. 82,000kms na odo ko. akala ko before after kong magpa PMS lalakas ulit, pero hindi nangyari. ano kaya problem?

[Ungas]

Baka naman nasanay ka lang sa gas enigne ng Previa? Or engine innards may have finally settled in. Another possible theory is added weight of bumper and larger than oem spec tires that adjusted your speed readout.

[afrasay]

could be the clutch system.

[kiper]

nagpalit ba ng bigger tires si kuya boybi..? if yes..mababago talaga speed read-out mo..saka mejo hirap na rin ung makina because of the larger tire over-all diameter.

[mikaztro]

Yup. Did u change ur tires to bigger ones. Surely it will be slower but better when you have the momentum. I for one experience it when I changed my tires from 225/75/15 to 30 x 9.5 mud tires. Or it could be the mis matched spark plugs.

[ARB]

when you change to bigger tires the speedometer reading will be the same it is the actual speed that will differ with the readout. how big is the difference of your new tire to the old one? acceleration will be compromised, automatic ba car mo? you might need to change the ATF. also air cleaner. what kind of oil did you use?

[Jeepcruizerph]

opo air cleaner big factor din baka nakalimutan nilang nilisan pag ka change oil

sa amin xwind madaling madumihan almost once a month ko nilinilnis...pagmisan nararamdaman ko na mabagal dahil madumi pala yung air cleaner

OT:
arb: diba iba iba yung mga atf fluids may ordinary and may mga dexron, or 2- 3 or etc... may alam ka ba na site that is comparing this atf fluids? or yung mga information nila

magiging mabagal ba ang pag shift dahil sa lumang atf? di ko kasi alam kung magkano aabutin ng sa prado ko...baka papalit ko narin :D

[fierari]

gear oils?

[boybi]

ngayon lang ako nakapagpost ulit, brownout kasi the whole day dito.

i changed my tires from 265/70R16 to 265/75/R16, not a significant increase in diameter. but this was more than a year ago. napansin ko lang ang paghina ng engine mga a month ago, so hindi rin siguro ito dahil sa bumper. i first thought that after ko magpa PMS ng 80,000kms e babalik ang power, pero hindi rin.

air filter ko pala is Finer Filter, meron bang effect sa engine power kung nasobrahan or kulang yung oil na nilalagay sa filter?

regarding sa gear oils, ito ba yung sa diffs or sa transmission? pano ko malaman kung kulang na or kelangan ng palitan?

[afrasay]

gear oil? have it check sa service station. they will do the finger method (hindi yun nasa isip ninyo ah). makikita din kung ok ang gear oil mo (kung may halong tubig). but better change it every year or two. ang pagka alam ko pag may problem (kulang or old na) ang gear oil maingay o maugong o makalansing ang tunog.

[GlennSter]

might be the clutch?

[afrasay]

yun nga might be the clutch. 82,000 km na, big vehicle, strong engine.

Pag kulang sa langis ang FF mo, magpupulbos ito at papasok sa makina. Kung sobra naman, mahihigop ito papasok at mag-iipon ng dumi at alikabok dun sa chamber after the filter. Tama lang na maging blue ang foam, pwede naman pigain ng ang foam pag sumobra ang lagay.

Nakakaramdam ka na ng sliding pag nananakbo ka sa highway, lalo na after shifting into 5th gear?

[boybi]

July 2001 nabili yung patrol. considered bago pa ba yan?

ma try ko nga yung 5th gear method tomorrow. pano na kasi yun? habang naka stop, shift to 5th gear tapos dahandahan i-release yung clutch? kapag namatay ang engine, good pa yung lining, kapag hindi namatay, kelangan ng palitan. tama ba?

ano bang feeling kapag sliding?

[Ungas]

Pag shift mo sa 4-5 gear delayed yung power ng makina sa apak ng pedal.

[frt]

Sliding sa A/T naman tumataas RPM when the tranny shifts

[afrasay]

Pag hindi namatay ang makina when you start from 5th gear grabe na yan. After awhile you will get use to the acceleration of your patrol until the next stage of clutch wear comes in, that is, when you feel the lag on the lower gears. ask your suking casa on what is the usual clutch replacement for a patrol. I replaced my clutch on my 80,000 km mark.

[boybi]

kung yung clutch nga ang salarin, does it mean nagiislip na ito kaya hindi ko na ma achieve ang speed na naaabot ko dati?

[GlennSter]

parang ganun na nga po manong boybi....
