Notice I specified unlit. It is scary but I have had a few responses through the years about how do you not burn things!!

So I slapped myself around a bit and started to look for a vacuum leak. I haven't found anything particularly bad. Anyone have any tip or tricks on looking for an intake leak? I tried pressurizing the intake to a few PSI with my compressor and listening for hissing, but it has been really hard to localize- possibly going through an open intake valve?. One thing that I was wondering- how much of the stock 1.8l engine's cycle has all of the intake valves closed? I did find a better place to put the fuel pressure regulator's vacuum hose, but wiggling stuff around hasn't brought me any closer to bringing the vacuum down to a more appropriate value.
