    then belt finally snapped.
    tirik engine.

    in some engine designs,
    cylinder head, valves and seats, and pistons, are designed in such a way, that no metal will clash against another (valves versus pistons), when the timing belt/chain breaks.
    my sentra engine is like that.
    what is that term?
    interference engine... resulting to tukod when the timing belt snaps.. making the valves baluktot and sometimes makes butas on your piston

    Meron palang ganun? Yun hindi siya tutukod? I mean hindi mag-aabot ang valve and piston?

    yup.. but mostly interference ang engines natin.. that is why when an engine fitted with a timing belt suddenly dies, check the belt first before restarting.. if you force it to restart then say goodbye to your engine if the timing belt snapped.

    sentra 1.4 .
    one time,
    lumuwag yung timing gear bolt.
    kumalas ang chain at tumirik.
    kinabit lang ng mekaniko uli, at umandar agad.

    that was the largest volume of exhaled air in my life.

    non-interference engine - iyon ata term dyan doc.

    i think my dad's good ole galant sigma was like that. our suki mechanic told me that that car's timing belt snapped once before and no damage was incurred by the motor. hinila pa nga daw nila papunta sa talyer nila.

    yun na nga.

    ano na kaya si post-er?
    naluwagan na kaya niya yung distributor at na-paikot na niya yung distributor?
    the procedure is in youtube.

    pag ayaw gumalaw o mahatak, spray liberally with wd40 and pukpok mildly.

    we used to paint the crankshaft pulley marks with typewriter corrector fluid, for live timing adjustment using xenon timing light. the neon timing light is simply too dark.

    sir, hindi ko pa natanggal ang rotor. Im afraid that it might be broken, sarado pa naman mga auto shop ngayon due to ECQ. I badly need the car now wla kasi public transpo. Anyway, I will take the advise of spraying wd40 baka luluwag.

    Thank you so much for your suggestions mga masters, it will help a lot!

    Some rotors are locked by a tiny beveled screw. If stubborn still, some heating using a torch and a reasonable whack of a mallet should loosen the rust.
