Thinking compression ring because no smoke.
As you know replacing a ring requires the whole front of the engine to be taken out. What else should be done, or should I yank the engine and rebuild the whole thing?
Do a leakdown test on the weak cylinder and listen for where the air is leaking out to diagnose. Most internal engine problems related to compression warrant a full rebuild, the exception being a single valve problem.
