    there as been so many mods on the oil pump/assy on this car
    check the oil pump hexagonal drive
    check the shaft is 100mm long not 65mm
    check the hexagonal drive in the balance shaft
    if its had the short hex drive it will have rounded out the hex in the balance shaft and even the oil pump
    also check the chain drive if its a 140bhp engine
