    Port and polishing could be helpful to your top engine parts, pinakikinis nya lahat ng tuppets at yung mga rebaba ng mga parts. Imagine those metal parts running smoothly walang tagas o singaw na di kailangan sa loob ng makina. On the other hand, pag di ganun kaganda ang makinang gagawa ng port and polish, or di ganun kabisaha ang mga gagawa, might as well not do it. Baka mas masira pa ang parts instead of helping it run smoothly. :D

    oo sa gas engine may significant increase in power lots of my officemates had their heads p&p'd but i have reservations if it will have the same effect sa diesel engines.

    I've had my D4BB done, mas tahimik ang makina without the "clitty claking" sounds since then. :D

    With regards dun sa extra power, di ko na kasi nasukat, nagkasabay pag baba ng injection pump ko.

    Then it hit me after having it done, natural sa diesel engines ang maingay. :shock: Now I know if something doesn't sound right in my engine, that's when the overhead needs overhaul. :D

    hehe.... am taking up mechanical engineering sa ust... sabi ng proff na master ng M.E. nakakasira daw ng kotse ang port and polish and hindi daw totoo ang tipid ng gas... dahil... pinalalakihan raw nito mga daanan ng air... ninipis lang daw bakal at masasayang ang engine... hp gain lang daw... baka tumakaw pa sa gas... and kung ndi raw marunong gumawa... baka mapalaki pa gastos mo... dahil.... magstall paminsan ang engine... sayang lang... hehehe

    i believe him eh... hehehe

    nakakasira daw ng kotse ang port and polish and hindi daw totoo ang tipid ng gas... dahil... pinalalakihan raw nito mga daanan ng air... ninipis lang daw bakal at masasayang ang engine... hp gain lang daw... baka tumakaw pa sa gas... and kung ndi raw marunong gumawa... baka mapalaki pa gastos mo.
    AC::: Tama yung prof mo..... assuming that the P&P is done wrong. :D When done well ok naman ito. Pag smooth ang surface, less drag diba? Less drag = higher velocity. Higher velocity = more oxygen molecules. More oxygen, bigger explosion :D BTW, an diyan pa ba si Patrick Go sa USTe? Prof siya ng Electrical Engineering, classmate ko dati. :D

    Back to porting, i have no doubt na lalakas ang engine pag P&P. Kaya lang, pag diesel ang pinag-usapan, di ko na alam ang effect. I think im gonna play it safe and not have this done. And you are correct, kung hindi marunong ang gagawa, tope ang kalalabasan. Nakakatakot nang mag-experiment eh :D
