Did cyl leak down test and #1 way off, added oil to check rings pressurized cly, could see oil mist coming out of intake. Seems to be very minor leakage but can't explain why it's not misfiring. It's is fine at higher rpms, so I'm guessing higher compression pressures are actually sealing valves, could be that it's leaking on compression stroke but sealing when it fires.
