oil filter lines

One of the fittings will have a smaller opening thru it, it will restrict the flow of oil to the bypass filter. Only part of the oil will flow thru the filter. This is normal operation, if the restrictor is not in place, your oil pressure to the rest of the engine will be low or non-existent. ...Terry
