Yes, that's the old school method of determining the reason for a cylinder with questionable compression. Test dry, then test with oil, if comp jumps up the rings are suspect, if comp stays the same, that points to the valves are bad. You can use the oil trick with a simple comp test or the bleed down. Do a compression test and go from there, as was mentioned, and hope for the tests to run close on both cylinders.
Ho w much oil do you squirt in the plug hole? I was going to say plug port but plug hole sounds better.
