Oil heat continued
For this version of oil heat, I needed a stand tube for the oil sump.
Tubing was welded to a fitting
I was cut 3.5” which hopefully only allow oil to be removed from the sump at a level great than 4.5 quarts. If the sump gets below the level the tube will be come uncovered and protect the engine. This is needed in case of a hose break (unlikely).
I needed to move my oil sump drain to a new location since then hole is now being used by the stand tube.
The oil suction filter cap was removed and drilled and tapped for the quick drain plug.
I wanted to control the air from the preheater so a door was fashioned,
and a control cable was installed to allow opening/closing the door in flight.
