Before I (temporarly) reinstalled the intake and returned the engine to proper configuration I placed a long peizo electric flex strip over the two front channels. One end is secured by bolt, the other end is expoxied into the cavity. I ran the wires up the rear 'firewall'. This way I should be able to check if the the flex strip changes its orientation significantly while I run it in the garage (indicating that the epoxy is being pushed out). I realize their would be air leaks, thats okay, I'm not going on a trip or anything, just running it in the garage to see if I have plugged the only hole, and to see how it holds. I put some liquid gasket around the intake ports near the broken bolt. Then I gave it a oil+filter change and let it rip. I'm glad to report, no oil leaks. The engine sounds great. The flex strip hasn't changed resistance since installation, I'm going to wire it to a solid state LED bar display in the engine compartment that will indicate visualy if resistance has changed. Before I call the repair a tentative sucess I'm going to replace the oil pressure sender and verify a stable reading there. I've been working on the bolt carefully tonight. I broke a couple of my nicer small bits, so I'm thinking of having someone qualified work on it instead:). Anyway, thanks again for everyone's support and technical insight. I very much appreciate it! I'll post a picture that will indicate where the hole was found, and the repair. -Nate vin11501 > > Do not attempt to reinstall the intake manifold without repairing the > broken bolt.
