Ok, I was not able to find any leaks with the WD 40 trick.
I did borrow a vacuum pump from a buddy as well as a vacuum gauge.
The vacuum pump held true on the EGR Valve and I also heard the EGR valve return once the pump was pulled off the valve. So, I think the EGR valve is good. I check the PVC Valve and that seems ok, I can hear it rattle when shook and I see no cracks or anything of concern.
The odd part, It seems to idle smoother without the vacuum hose connected on the top of the EGR Valve. Does this Indicate anything?
