Oil Drain Valve Torque

[larry philbin]

Does anyone know the torque setting for an oil drain valve?

Thanks.

What engine? It will make a difference.

Thank you. I have a Lycoming O-235 and can't find the spec in the maintenance manual. I am putting in a Saf-Fly quick drain oil valve (aluminum).

Try here: https://www.lycoming.com/sites/default/files/SSP-1776-4 Table of Limits - Complete.pdf

I think you want Part 2, Table 3, which doesn't give a torque value, but rather an angular measurement after contact of the sealing faces of the crush washer.

Thank you so much.
