Why would oil leak into your air filter on a 1991 Chevy lumina?

Two possibiities: 1. your positive crankcase ventilation valve is clogged. A new one would cost aroung $4.00. 2. If your engine is a very high mileage engine you may have some "blow by" causing oil vapors to be forced back up through the intake. The only remedy for that is an engine rebuild. If the PCV is okay and the engine seems to run okay I don't think I'd spend the money to rebuild the engine in a car that is that old. Just keep wiping out the excess oil and drive her until she is completey worn out.
