The other day i was under the car inspecting everything and i saw oil on the oilpan. I just had a new one put on about 6 months ago and the pan isnt dented at all. I couldnt tell where its coming from. If theres a new gasket and oil pan where else could it be coming from the oil filter ?? I was told tht is only supposed to be hand tight... what it the actual spec on how tight i should make it ? Any idea on where the oil can be coming from ??
