The FA motor sucks a decent amount of oil through the PCV valve. Pull the rubber hose off where it meets the intake manifold and you will see the oil inside the hose and on the nipple of the intake manifold.
FYI, we are making over 400 HP / 400 TQ and revving the motor to 9000 RPM with a fully built motor using forged pistons. The car has over 5000 miles and we have never had to add oil to the motor. We did install an AOS when the car had 100 miles on it though
