2.76 open to 3.55 Sure Grip...expectations too high?

I cannot accurately express my level of annoyance at the leaks in my shop air, although I'm sure you understand. The compressor is back in the corner, where a leak lives, and a line is plumbed up and over to the hose reel, where another leak lives. So, I get to enjoy the sound of hissing in stereo whenever the system is charged. I always kinda just tuned it out and thought I'd deal with it "someday" until I actually needed to LISTEN for something, and that something just so happened to sound just like the shop air leaking. I will be addressing my list of priorities that is never-ending.

SO. I don't feel the need to say this was my first leak down test. I thought I was supposed to run pressure closest to the compression psi (~130), without exceeding the equipment limits (100psi), so I decided on 90. I'm going to run another test on all of the cylinders at a lower pressure and see what the results are. I did notice several times that the engine seemed to turn over backwards at about 40 or 50 psi, but then the pressure would hold once everything settled in place. Also, per the instructions, I merely disconnected the PCV hose from the valve, but did not seal the valve covers afterwards. I interpreted this as I was supposed to listen at the PCV valve for leaking.

Again, I'm going to have another go at this, hopefully with some better wisdom going into it. I also paid some attention to the intake and header bolts, since I seemed to have forgotten to visit them again after the initial break in. Needless (or not) to say, most (if not all), had a bit of tightening to do. I also noticed some oil accumulation near a couple of the intake bolts.
