I have an IO-360 A series engine and want to put a Christen inverted oil system on it. This is an angle valve, horizontal induction engine with the air plenum under the oil tank.
The paper work I have says "extended modification required", but doesn't explain what that is. The modification is for the oil pick-up for when the plane is right side up, and says an 812-1 weld on boss. The boss it calls out is only long enough for the pipe thread in it. If the weld on boss has to be in the middle of the oil pan, like the origional is, it would require a long enough boss to be welded to the floor of the oil pan, extend through the intake plenum, and be welded to the bottom of the plenum. Has anyone done this modification or had this done? Any information would help.
Thanks
Mike
