mausok sa arangkada

[ghosthunter]

patulong lang po.
may nissan series 3 kami.
pag idle at mabagal na takbo ok naman po sya.
pero pag mablisang takbo lalo na pag 4-5 gear at hi rev, mausok na sya.
napansin ko yun nung tumatakbo kami sa SLEX at paakyat sa antipolo.

ano po kaya ang possible problema? loose compression na kaya to?

I was thinking loose compression or just enough for engine oil to leak up into the cylinders. Do you re-fill your engine oil every few weeks or months?
