    Opinion ko lang po ito, im not saying na sigurado ang mga ito.

    -Overheating
    -worn out valve seals
    -worn out piston rings
    -age of car
    -delayed oil change
    -driving habit

    ..correct ka dyan brader,.. mostly nga worn out piston ring/s.. one of the signs? hmm? some or many other vehicles can experience less top-end power,.. paghumataw ka, parang bitin na humatak,..less torque pati!..imho!

    worn out piston rings is one cause of low compression. early sign is white smoke sa exhaust pipe.

    pag naka-aircon lang ba sir? baka madumi ang throttle body mo. search ka tungkol sa throttle body cleaning.

    siya nga pala mga sir, paano nga pala ang process nang pag check nang compression? di ba may 2 type yun? saka, tama ba, wala nang engine brake kapag worn-out na ang piston rings?

    Ganito din problema ko. 2 years ago ako nag pa overhaul, pero mausok na siya ulit. pati sa breather ko going to carb pumapasok ang oil due to hi pressure.

    parang kailan lang tas eto overhaul ulit.. magastos ah..

    Kung na overhaul na malamang isa lng ibig sabihin. Hindi maayos ang pagkaka overhaul mas maganda sa kilala at mahusay mag overhaul mo paayos. Hindi lng kse basta palit ng piston ring yan.
