    Most common cause we see for an oil leak in the area of the engine you are replacing parts in is the oil filter stand gasket. Also check the vanos gasket and vanos line and washers.

    For the coolant leak you need to pressure test the system as it could be coming from any of the parts you already replaced or someplace else.

    The oilf filter housing gasket may be cause of the oil leak . Has the breather system been updated with the correct tubes? The cooling system needs to be pressure tested. call 617-773-3900 for further assistance.
