1989 Ford Bronco II, 6 cyl, 150,000 miles. Just had the engine rebuilt and it has "used" a quart of oil at 1100 miles. No "leaks"; keep it parked on concrete. Does not smoke. Any ideas?

Check the PCV and associated hoses. Also check with the shop that rebuilt the engine.


Yep, make sure the PCV system is fully operational, on the engines I did the very first oil and filter change was at 1000 miles, then you start checking oil consumption if you,think,you have a problem, 1000 miles gives time for the rings to seat, after that if the oil consumption is still that high then something is not right, voice your concerns now so they have a record of it in case it does not stop soon.
