How tight should oil plug be.On my 2000 protege the torque is 30-41 Nm.what a range I just tighten it with socket and socket wrench.The crush washer is changed every time to prevent leaks is there a danger of overtightening.I once torqued the oil filter and then I coudn't get it off.I just put that on as hard as I can by hand.I don't use the 3\4 turn after gasket contacts base method.How do you convert inch\pounds to foot\pounds and newton\pounds to foot pounds.I have a torque wrench but it only goes up to 265 inch\pound.
