I need your combined experience to help solve a problem I have with my 912A.
The engine runs very nicely. Smooth, good power, reliable as can be. However, I'm using oil at about 4 ounces every 3-4 hours. The engine has great compression, and the differencial pressure readings are 79-80, 80-80, 80-80, 80-80.
The engine does not visibly smoke, but oil consumption is consistent.
I'm currious as to what may be the problem? Where do I continue to look? I've checked the cylinder walls with a scope, they look fine.
I'm wondering if a cracked oil control ring might be the source of the consumption.
Thoughts?

Cheers,
Ackselle
