An oil circulation block for an automotive engine is provided to improve engine efficiency and response property because a check valve and a bypass valve are set up in the flow path. An oil circulation block for an automotive engine comprises a block(50) in which an oil filter(60) is formed, a discharge hole unit(52) which is formed in the block, an inlet hole unit(54) which flows the oil cooled in the oil cooler into the block, an inflow path(62) which is extended from the inlet hole unit to the oil filter, an exhaust path(64) which is extended from the oil filter to the block outer side, a bypass(66) formed between the discharge hole unit and the inflow path, a check valve(70) formed at the bypass, and a bypass valve(80) formed in the bypass hole unit.
