bad idea or terrible idea?

I would do a leak down test to see how much blow by you are getting. What was your compression test method and brand of gauge? Also did you check all the machined surfaces on the block to make sure they are flat, with a straight edge and feeler gauge? If the block is warped it will leak oil like crazy. Also where is the oil coming from? and do not say "from everywhere" it has to be coming from seals, gaskets, cracks, etc. The idea of venting more crank case pressure is good, but I do not see it as needed in this case, the valve cover is a little easy to drill into. Who did the machine work and assemble on the motor again?
