Abstract: An oil filter system for a vehicle may provided at a cylinder block of an engine for collecting engine oil from a blow-by gas generated in a crank case. The oil filter system may include a blow-by path to recirculate the blow-by gas so that the blow-by gas generated in the crank case is combusted together with a fuel-air mixture, a filter case that is a space formed between the crank case and the blow-by path, a filter partition disposed to divide the filter case into two spaces, and configured to collect the engine oil contained in the blow-by gas, and an oil pan mounted in the cylinder block for collecting the engine oil that have been collected by the filter partition. The filter partition may collect the engine oil in a forward direction flow and a reverse direction flow of the blow-by gas.
