It appears my EGR is in trouble.... tried to deflect by pushing up on the bottom through the metal body, barely budges. Hmmm. Probably need a new one. Pulled off the little hose and a bunch of cream colored "sand" (very fine) poored out. Maybe half a thimble of the stuff. Looks clear as far as I can see down this vacuum hose, which actually isn't very far. And I couldn't feel any vacuum on this line at any point. Is this an easy off-the-shelf replacement or is it time to check the junkyards for this little hose?
Can this cause damage to the engine?
And how much should an EGR valve cost?
