The first 240 I had, near as I could tell, the EGR valve bound up at some point and hadn't worked in forever. I also had the intake off several times for one reason or the other. With the first motor, it was definately slick with blowby, the second, I never noticed any buildup.

The EGR includes a butterfly linked to the gas pedal that develops a bit of vacuum at idle or part throttle and none at wide open, so it doesn't take in EGR gas when the pedal is floored, which is about half the time on a 240.

So, I don't think it limits performance by buildup or inducing EGR at WOT. If it still works it probably takes the edge off of NOx production, which anyone with breathing problems will appreciate on those bad air quality days.
