Oil separators?

[ew1usnr]

This is a gizmo (in black or aluminum finish) that is aimed at new Mustang V-8s:

It is an oil separator that goes on the hose going to the pvc valve. It is supposed to keep the intake manifold clean.

See: http://www.cjponyparts.com/jlt-oil-s...3/p/OILSEP4-V/

"Easily one of JLT Performance's most popular products, their oil separator will help keep oil out of your intake. While your engine is in the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors, can coat your intake runners, throttle body and even dilute your gas, lowering its octane level. And a lower octane rating means less power!"

If it is a LARGE amount of oil, maybe it would be a problem, but the engine would be having problems anyway. This product is being promoted as something to put on a new car.

Is there any point to that? Do any of you use one of these?

I know that my 260 V-8 has some steel mesh upstream of the pvc valve that is supposed to catch oil droplets. Does the new Mustang V-8 not have anything like that, making an aftermarket oil separator necessary?
