Burning Oil conundrum
Aloha!
The original owner of my '64 replaced the original 327/300 with a '70 Chevelle 350. The engine burned a quart of oil every 500 miles or so when I first drove it from Houston to Long Beach but I never saw smoke. I replaced the carburator with one too big which fouled the plugs (fast) so I thought it was valve guide seals. Did a valve job and the guy said the carb was too big and that it didn't need a valve job. Good, no more fouled plugs but what was minor smoke got worse.
Once at operating temp, after idling or low rpm driving, upon accellation I get a cloud. Bad but not horibble disaster type, But then it mostly goes away. Mostly. I punch it and yes there is some blue smoke but not a lot and its not continuous.
Problem is mostly on passenger side but still, both sides. Compression psi when I tested it upon arrival here, just to know what it was, readings are, from 1-8 are 145, 155, 145, 155,155, 150, 155, 175. It made lifter noise on the passenger side after the valve job (not prior) but not bad and not continuous. Mehanic says that causes the smoke... only...its one lifter on one side.
Do those compression numbers sound like rings? The scenario is confusing. I don't know what else it could be. I'd appreciate input. Check my pics. When I bought the car, the engine was so clean you could eat off it. Based on what I know, the second owner would not have found a worn engine acceptable.

. Mostly. I think my plugs are fouled enough again that it no longer hums at idle, but not far off..it was perfect, smooth, steady rpm recently however. Some 3500 rpm between shifts might help that a little.
