Tama nga yung nasa link na sabi ay prone mag clog yung pag short trips at madalang patakbuhin ang car, so possible clog nga ung sa ken kc madalang ko gamitin yung car, short trips pa (12 km a day lang tapos 3 times a week ko lang ginagamit kotse).

Theveed, i have no idea kung ano ung compression test? Ano ba giagawa sa ganung test?, may instrumento ba na kinakabit?

hey bro, no problem. also, yung hose sa intake (or any hose (vacuum hose) sa engine) ay talagang titigas over time, mainly due to heat. also, about the Compression Test. you have to take off all of the Spark Plugs and screw a Compression Tester (or a pressure guage) on each of the Spark Plug hole. pero ginagawa to one by one, and you have to crank the engine at least 5-8 seconds so that you could get an accurate reading.

anywayz, I think you dont need to do a Compression Test since na malakas pa naman ang takbo ng Corolla mo. pag humahatak pa naman and hindi nag mi-miss fire ang makina, then it should be good. but you can still do a Compression Test para lang to make sure and for peace of mind.

aite, peace.

wala na pong manipis na asul na usok ang corolla ko now after tune-up and PCV valve cleaning.
Isang tanong na lang po, yung hose ng PCV valve ko eh antigas na, pede ko ba palitan yun ng fuel hose lang? kaya kayang i-resist ng rubber fuel hose yung temp ng air na nagfoflow dun sa PCV valve? ang mura kc ng fuel hose eh, P30 per foot. need ko lang eh mga 3/4 foot. Please advise po, maraming salamat.

hey bro, thats good na ayos na din ang problem mo! also, pwedeng pwede din ang Fuel hose for use in Vacuum. at di naman masyadong mataas ang air pressure and temperature na lumalabas sa PCV, also oil resistant din ang Fuel hose kaya ok lang yun para sa PCV.

aite, peace.

normally the pcv hose is preshaped since may mga liko sila. if you use a regular fuel hose it might kink where the hose turns causing the hose diameter to get smaller in some areas which is not good.

nakabitan ko na po ang bagong hose ng PCV valve, pwede naman po putulan kaya wala po sa syang kink, nailagay po ng maayos kc madali lang po putulin yung fuel hose at maiayos ang liko.

hindi ko sana basahin tong thread na ito dahil akala ko hose lng yan pcv na pinaguusapan nyo valve pala yun at malaki pala epekto neto sa takbo ng oto.

it really got interesting when KBR made those simple but very useful explanations on what it is lalo na posted those links which are very helpful and napakaganda ng explanation pang dummies talaga hehe.

sir KBRmay techniques pa ba sa pagtangal nyan valve na yan o hinuhugot nlng? also, yun pcv na yan napansin ko sa oto ko pareho ng itsura dito sa picture ay nakalagay sa ibabaw ng intake manifold ba tawag dun carb type ksi akin---eto yun metal na in between ng carb at engine block tama ba? eto na kaya yun parehong pareho ksi ng itsura dito sa pic ng link thnx!
