Message So I have been working on this damn car for almost a month now and I am just about there. Sooooo, I hooked up the boost leak tester to find all the leaks to tighten everything up. The last one was under the intake manifold (A bolt was broken off into the lower manifold that I had to drill and pull out), so after I pulled out the broken broken bolt, I put it together and AGAIN same boost leak. I figured it must be the valve cover so....I pull it apart again, this time taking off the valve cover (brand new valve cover gasket). I tightened it down very well and also with the upper manifold (new upper to lower manifold gasket) got it all together and again same leak but I can't figure out exactly where it is coming from! I can hear it, and as far as my finger can feel down between the manifold I can feel it but not exactly where. What the hell is it!!! Can the lower manifold be crack from the bolt breaking off. I don't know how the bolt broke in the first place. Help me out

Sorry if this is a lot of jiberish.
