Jim, what I did was turn the engine on it's end, then to tape off all the obvious holes; the full flow lines, the opening in the case to the oil fill where the stud was located, this left the stud hole and any other opening able to release pressure. By securing the air chuck to the oil pressure sender hole atop the oil cooler and holding the chuck open and setting the compressor output to 20 PSI, I was able to supply the case with about 12-15 PSI of positive pressure, as read on the output of the compressor. There was an immediate air leak around the crank at the rear of the case, but minimal. As I drilled and tapped the case, there was a steady amount of shavings and metal dust, as it were, being blown out of the hole (the path of least resistance, I couldn't tell you if more air leaked out anywhere else while I was drilling, I had run out of hands at that point). The compressor only came on 1-2 times during the whole operation so all-in-all, it seemed like the case held pressure enough to accomplish the job. However, when I was drilling the case for the full flow, as per instructions from Berg (essentially the same as what I did for the stud replacement), I did get a small amout of oil and blow-by air from under the cooler when I pressurized the case in the same fashion. I'll have to pull the oil cooler off and maybe replace the seals under it, those may have been damaged by the pressure. I'm not sure, Berg called for 25-40 PSI, I think I split the difference at 32 PSI or so. It seemed like it all went well, but like I said, the proof will be in running the engine. With all the work I've done (new jugs and slugs, head work, full flow, helicoils, etc.), break in will be by the bbok with lots of oil changes until I can be sure it's clean. The body work is coming along, the Wizards have moved into sanding and such for paint prep, hopefully it won't be too long, unfortunately, my car carrier I borrowed is out in Arizona with a Shelby on top of it. I'll have to find another mode to get the Notch home. David Walters '73 1600 L Notchback S.
