Does anyone know the correct name of the circled piece? It's mounted on top of the manifold. There are 5 small holes beneath it and I'm wondering how to properly clean them out. I went to a pull-a-part junk yard yesterday and removed one from that car and the holes were almost completely closed from build up. I stuck a small screwdriver in to remove the buildup but afraid of doing this to my son's car. Not wanting that build up to go somewhere that it shouldn't. Is this something that would require removing the manifild to clean safely?
Thanks in advance for any advice.

 

You people just don't respond, or do I need to be in a clique?
