so i got this h22. i was changing the oil one day and i accidently overfilled about 2quarts. later i realized my mistake, so i drained the oil and put the correct amount back in. the problem is, my oil lamp starts to flash only after i drive for a while.... i looked inside and i saw oil pumping but then after i take it for a test drive (my oil lamp turns on) no oil is pumping?! a clogged oil pump is my guesse. HELP!
