Mga bro, what are the ill effects of overfilling your engine oil? Kase, my mother-in-law's car (civic vti 99), when I checked dipstick, the oil level was way above the high level (parang 1/2" higher). I noticed oil leaks na sa cylinder head cover (maybe because sobra nga oil, naghanap ng lalabasan yung oil -- tama ba?). What other parts kaya affected? Thanks in advance!
