    It might be coming from your Turbo (since you mentioned lack/decrease in power). Have it checked aSap. mahal yan pag nasira.

    do all d4d innovas have turbos? may ganun din po kasi na tunog yung innova namin pero mahina lang noticeable at high rpm pero wala naman loss of power.

    Yup, D4D innovas have turbos. (albeit no intercooler)

    Pag medyo mahina yung hissing sound then lumalakas engine then normal yan, it means the turbo is kicking in. Pero mag malakas yung hissing sabay ng paghina ng hatak then I guess singaw nga sa turbo yan. It probably means nag kick in na yung turbo pero imbes na pumapasok sa intake eh sumisingaw resulting to a very rich diesel mixture (kasi mas malaki ang amount ng diesel injection pag spooling na ang turbo).

    Probably a gasket that went wrong.
