Using oil drain plug as a tap for oil return

Has anyone ever used the oil drain plugs hole and put a fitting in there with the same thread as the hole and a barb at the other end for return line. what are opinions on that?

Because since theres actually no pressure on the lower pan it would be perfect. since oil will be dropping from above and it wont go back in the line.

i think it wouldnt work well because theres oil in the bottom of the pan. no pressure, but the force of gravity is all that pulls the oil down so if theres already oil down thereit would block it due to pressure of gravity

"Also I have an oil pump pushing that oil so it will defently go in the pan. only problem would be wen i turn off the car but the drain hose will be coming from above so there wont be problem of oil leaking back into the line while pump is off. perfect. thanx.

BTW this is Streetzlegend on my friends name."

NO you need to have the return higher than the level of oil. With your rear mount either drain it into the oil cap, valve cover, timing cover, or upper oil pan.

Is it possible to overfill the valve cover and cause a valve to float?

The amount of oil in the return should be very minimal. The STS systems all drain back into the valve cover. Valve float has nothing to do with oil any how. Valve float is when the rpms are so fast the valve doesnt stay in contact with the cam, the spring cant keep it seated at those speeds. Also many motors have oil squirters that direct oil onto the cam lobe (our motors have oil passages in the cam shaft bearing caps to keep them well lubed), so there is oil up there to begin with. IF there was to much oil it could be sucked in by the PCV, but again I think the return should have very little volume of oil.

Not to mention there will always be oil in the lower pan since the pick up needs to be submersed at all times.
