Valve Cover Oil In/Outs

How hard would it be to modify a valve cover to use for oil in/outs like the one in the link below?

hehe I already have a pan tapped, but does the valvel cover oil in/outs work better. That is the question.

My opinion is it is too tight of an angle and the possibility of oil backing up is greater.

For a gravity fed turbo system, the greater height difference between the turbo and the oil return, the better. Some of the early Minnam turbo kits had almost a horizontal line going from the turbo to the oil pan and they were known to smoke the oil due to poor flow. You want a fat line and you want it to drop a ways to get clear of the turbo.

Unless your turbo sits very high, it wouldn't be as feasible to go to the valve cover. The oil pan gives you the best results and allows the froth to settle before going back through the engine. It is also goign to be putting the heat from the turbo into a reservoir, as opposed to right on your valvetrain.
