Vacuum port identifier

[dstock]

I pulled the valve cover this evening, & right away noticed cylinder #2 jet valve was stuck. When I took it out, the tip end was missing, leaving it open. I welded the open end shut and reinstalled. I also removed the jet valve adjusters from the rocker arms, so now the jet valves will remain closed at all times. I think I’ll order the “JVE” kit and replace the jet valves.

That did solve my problem….no more blow-back from that port. I’ll have to test drive it tomorrow.

So are you saying that “No” vacuum hose connects to this port?

Thanks for all the help/info.
