How many people have tried to reduce oil consumption by installing a catch-can on the pcv line into the intake manifold to reduce oil ingestation? I've tried a new pcv valve, AutoRX, and now different brands of oil, thinking of a home made catch-can (air/liquid seperator for compressed air lines) just for fun. My spotless Civic engine (ran on M1 for first 100k of 131k total miles thus far) drinks 1qt per 2-3k miles without visible smoke or leaks anywhere. Quite liveable by my standards, but it would be more peace of mind if I don't have to check my oil every 1k miles (2 weeks @ my commute).
