Check the passage under the valve for clogging. This would result in excessive back pressure when EGR valve opens.

Ok here is the whole story.
Hose keeps blowing off the bottom of the egr valve. It first started when the port of vacuum got hot and melted so I replaced it then I replaced the vacuum modulator because the hose kept blowing off it. Now the hose is blowing off the EGR valve so I replaced it but it is still blowing off.

Check for clogging of the passages.
