    I can hear tiny rattling sounds from my FD's engine lalo na kapag acceleration. It's like a bicycle kadena hehe. pero masyadong pino at mahina lang. you can't hear it of you won't look for it. but kapag nasa asphalt ka maririnig mo talaga kapag mag accelerate ka gradually. ok naman ang power ng engine, tsaka hindi naman madalas nangyayari,. pero meron rin times na kapag full stop ka, pag tapak mo ng gas pedal may "TOK!" kang maririnig sa engine. is this engine knocking?

    naremember ko lang kasi dati dito sa tsikot meron rin thread about engine knocking ng vios ba yun or ano, baka kasi meron nang issue ating fuel quality? im just using unleaded. baka bumababa na quality ng fuel natin sa pinas?

    Been using Shell Unleaded for my 2004 Altis since I got it 2nd hand last year. No fuel knocking problems encountered so far. I suggest filling up with premium gas next time you gas up and observe. If the problem goes away, your engine is acting up on lower octane rating fuel.

    the noise that you have been hearing is actually valve tappet noise. this could be due either to low octane fuel, water contaminant on fuel or valve tappet out of proper clearance. this occurs duiring acceleration. try using clean fuel with higher octane rating (95-97) or have your valve tappet clearance adjusted to correct specification...
