    gud day!

    hindi pa naman nangyayari sakin pero assuming na may mahulog na bato na
    kasin laki ng monggo sa opening ng oil cap
    saan pupunta yun o iikot? babagsak sa baba ba yun?

    may effect ba sa mga internals. hindi kaya madurog yun tpos masira mga inernals, seals or ma wash ng oil din. thnx!!

    You mean inside the engine? That will cause havok inside the engine. Suggest you change your oil ASAP and hope it goes out. Check the dirty oil if its there. You can also cut open your oil filter and lokk for it there if its not in the oil.

    Depende kung saan nahulog, kung anong type ng makina (how it was designed) at kung hindi mo alam about it tapos pinaandar mo yung makina.

    Kung malapit sa timing chain or belt (internal) there's a chance na mag circulate yon and could jam the timing chain/belt teeth, oil pump, tensioner, etc. Kung sa valve train it might interfere with valve timing although highly unlikely unless sa loob ng valve springs siya napunta.

    Once you know pwede mo naman tanggalin yung valve cover tapos hanapin mo. Emergency cases pwede mo gamitin yung old gasket pero since tinanggal mo na when you can do it the earliest, replace mo na yung valve cover gasket mura lang naman yon.

    If it's really small and easily crumbles ok lang yon it might just get filtered off by the oil filter. Tapos ma-flush yon sa oil change. Also remember to remove oil pan if you suspect this. Check for metal filings na rin while you're at it tapos hanapin mo yung bato if it's still there.

    Worst case scenario siguro 4 or 5mm nut yung mahulog sobrang liit pero matigas at buo siya. It can damage all sorts of stuff in the engine and possibly make it at least run bad.

    Did anything happen?

    nice question.

    though di parin nangyayari sakin yan.

    imo, kung nadudurog naman ang nahulog na bato: magagrind din yan into smaller bits at masasala ng oil filter. not so much damage sa internal.

    at kung matigas talaga kahit maliit, parang bearing: just wish na mahulog agad yun sa oil filter. otherwise babara talaga yan sa inner mechanical parts ng engine.

    anyone wanna try???

    hmm kung bato yung mahugulog ipapa-takedown ko yung oil pan for cleaning; hindi ko idadaan sa drain lang ng change oil. mahirap na baka maiwan sa loob and mayari pa ang engine.

    edit: or drain muna ng oil, pag di lumabas saka lang takedown yung oil pan.

    meron na nangyari sa amin yan ...

    we overhauled a pajero na intercooler and found a 1/2 inch bolt inside ... grabe tumirik yung car nasira yung piston niya and mga gears inside...

    so it is a very very dangerous thing to happen

    sa akin naman, sa besta namin, my driver told me kulang na oil so nagpabilia ako, and dagdag kami, pagtingin ko sa oil cap yung part before the thread bungi na, ask my driver kung nahulog nya yung cap kaya nabungi, sabi nya hindi and last week pag check nya buo pa yun, so we opened the valve cover and swerte naman nakita agad namin yung parte ng oil cap, sitting between two valves, buti walang tinamaan, kundi gastos nanaman.

    kapag may nahulog sa oil filler na maliit na bagay na may kabigatan, at di basta lulutang sa langis, palagay mananatili lang ito sa ibabaw ng cyclinder head. kung madala man ito ng langis ay mahuhulog siya sa oil pan. dahil sa mayroong wire mesh ang oil sump, di rin ito basta basta mapupunta sa oil filter, o kaya mag-circulate sa oil system ng makina.

    if it falls in just open up the valvecover and take it out... this is assuming di mo pa pinapaandar yung makina.
