Gunk Engine Cleaner helped, as I ran the engine with it in the oil I could hear the change. The oil consumption is down but still high, a quart of more every tank, 300 miles.
I can get the engine to smoke out the tail pipe if I rev the engine numerous times quickly Idle to 4000 RPM and back. Steady RPM it's no smoke.
Review of items done and the engine:
154K 2.5 SHOC 2000 - Had bent intake valve, so I surfaced the head, glass plate and replaced and lapped all the valves. Engine runs great.
- New Subaru PCV
- All hosed clean and connected properly
- Seafoam in the gas and Oil
- MMO in the oil
- Leak down check, see numbers above
- Gunk Engine cleaner, seemed to help but did no solve the problem
- No external leaks
- Runs Great
Pretty much down to stuck Oil control rings, engine pull.
