yes, the seal rubs away the dirt on the hood in a line so i know its sealing 
there, and iwent thru the whole climate control system  and replaced the 
flapper seals w/ new ones and the spring holder thingy that always breaks so on and 
so forth..

i think its a cracked EM or DP....i get a "fast paced gargling noise" when i 
accelerate...let off on the pedal, and its gone.   ??
