Need a little help I did an oil change using the Scavenger total oil change system. It worked great. What should I toque down the tapered pipe plug to. There was red lock tight on the treads. I looked in the Maint. Manual but it did not show a torque value. The Oild plug and trany plugs have a torque setting of 14-21 Ft Lbs but nothing listed for the tapered pipe plug.
