2001 Accord oil is missing

Yes it can be going through the valve or valves. The compression can be good but there are three rings on a piston. Two are for compression and the bottom one is for oil. That one is likely the problem. Either way, I believe the car is burning oil and this can be done without a noticeable cloud of smoke behind you. What should be telltale is to pull the plugs out and note whether there is black or brown deposits on them. It could be a seal but you should notice some sort of leakage on the floor or ground.
