[Walt Fricke]

I'd try it without draining anything. Jack the car us as high as you can on the side where you are removing the tube. "Try" means putting a large pan under the case end of the tube in case you have so much oil in the sump the even at a high angle the oil level is above the case hole.

This tilt method works fine for pulling an exhaust valve cover to adjust valves or fiddle with rocker shafts or any other work there. Haven't tried it for pulling a tube, though. But you won't lose too much any way, and won't have to fuss with a full drain or to try to work fast on a hot motor. Though you could combine a hot (or warm) motor with the jack it way up approach.
