Check your oil flow when it is back together, as your cam is worn for quite possibly a lack of oil. Cylinder leakdown test sounds right. Make sure both valves are closed, then listen for air moving into the exhaust or intake manifold. If both valves are closed and you hear air moving, then you have a valve issue. I have seen an old crusty engine have a piece of carbon lodge in a valve, killing compression. Check that too.
