I'm betting valve guides are going to leak more than worn rings. Or hitting VTEC a lot at higher RPMs (3000+).
You're best bet to finding the leak is to mix up some Simple Green, spray the block down when it's cold, and wipe down any remaining grime. Fill the engine to the upper oil mark, watch for leaks and keep track of how many miles you drive to how much oil you burn. Easiest way to do this would be to check your oil after every drive and see how many miles it takes to go from the upper mark to the lower mark on the dipstick. The distance between those marks equals 1 quart.
The rear main seal (seal around the crank where it exits the block to the transmission) is a common thing to leak, valve cover, distributor seal are also known culprits. Look in the oil fill hole and in your coolant reservoir tank, if the coolant is a brown color or even creamy beige that could mean your head gasket is blown or leaking.
You can also check behind the crank pulley (has the A/C, alt and power steering belts on it) there is a seal similar to the rear main seal there.
