That's the thing. The valve snaps open easily. No hesitation, no stickiness, no deposits that would prevent it from opening completely. Btw, did anyone try unscrewing the thin bolts in the valve and actually taking the valve apart?
If you clean out the EGR ports you can completely eliminate the possibility that it isn't receiving enough exhaust gasses.
True... I guess I'll go and order new gaskets then...
