When I switch to a DIY oil change and install a Fumoto valve I hope have my questions answered.Just in case:
The F108SX torque spec is 18 foot pounds. It's brass instead of steel and uses rubber o-rings instead of crush washers like the steel oil drain plug. The steel plug's torque spec is 31 foot pounds so Fumoto warns not to over-tighten their valves. 18 foot pounds is the correct torque for the F108SX.
Edit: Fumoto may have revised their instructions -
Here are the recommended torque values to use for our valves. Please find the matching torque value with your Fumoto valve below: Warning: We don't recommend using the torque value you may find on ...help.fumotooildrainvalve.com
- Why does Fumoto not use steel for their valves so the torque can be the same as the OEM steel plug? Less torque seems to say less security of the hold. O-rings are usually more susceptible to destructive aging compared to a crush washer. So again, why not provide a steel valve that can be torqued enough to be able to use a crush washer?
- I don't see a place on the valve to grip with my torque wrench socket, so what are my options to get to the 18 ft lbs torque? Fumoto says not to use the obvious hex on the nipple.
- Has anyone left a Tygon drain hose attached & tucked away to the Fumoto valve between drains? Maybe secured with a clamp/tie-wrap to the nipple. Fumoto advises not to leave a drain hose attached because it could melt from the heat. Tygon will withstand up to 200°C so leaving it attached and tucked away would provide every tool I need for an oil drain to be in one place.
