Vacuum Line Multi Rubber Connector at Valve cover
 

Do the holes in this Vacuum Line Multi Rubber Connector at Valve cover all have to be used? What i meen is should we block the holes if they are NOT used?

Only three of those holes are used and the others should be left open. I'm trying to post a picture of the configuration but I used the pic for something else before so it wont let me add it.

Maybe this will work. go to the reply that I made on this thread and look at the pic.

Thank's Phil!

Maybe if you can explain to us where the vacuum hoses are connected if we are facing the car.Or does it matter where they are connected.

Is that the 3/2 valve? The black box on the cam cover? If so, that is part of the EGR system, can be by passed.

Yes Bob true.But because of our Air CARE system here we can not by pass it.Other wise it fails Air care and no tags on car.I just wanted to know if we block the holes if they are NOT used?

I have pics only of a removed system, wasn't smart enough to take before pics. May be able to find, will take time.

if you plug the line at the EGR valve then you disable the system without removing anything and all looks original.
