Ok, so i took off my egr off my 73 240z and now theres a gaping hole on the balance tube on my intake manifold....so i need some kind of block of plate or anything to block it off....have any ideas?

You could buy the "Euro-Style Balance Tube Polished and Plated" from http://www.ztherapy.com/

But that runs $160.

I was going to make a snide remark, but then I realized that my 71 never had EGR, so my experiences didn't apply.

screw that i made my self one out of aluminum =]

are you guys talkin about the hole that the EGR sits above on? my 280z has been popping like crazy after a headers and intake install. I plugged the bung on the header, but the EGR and the diaphragm is still open. Can I take off the EGR and block the hole with an aluminum plate? or will the off readings of the EGR blocked still cause the issue (hiccuping, popping in the intake, hesistation)?

Been tryin to get this thing running smooth for a while.

Any help is appreciated.

check timing or other vaccum leaks

I replaced all the vacuums, and timing should be dead on since it was running completley fine before the headers and intakes went on. i guess i can double check things. But does not plugging the EGR cause hesitation when applying initial throttle?

thanks.
