Oil consumption can come from several places and it doesn't have to be piston ring issues. Valve seals can wear out, valve guides can wear, PCV valves can go bad, intake manifold gaskets can leak.
Some careful investigating will let you know where it's coming from. I'd start by pulling the carb off and seeing if there's oil laying in the plenum. If so, then it's probably something like a bad PCV valve. If you see oil on the intake valve stems, then it could be valve seals or guide wear. |
Sorry to get your goat, but these were on brand new engines, not just one but two. Every part in the engine was new. Burned a quart every 100 miles. Took the wrist pin out of the oil land, and not a drop of oil burned. BTW these were professionally built, not by me.
