and check the oil sending unit i had a 2.3 just pouring the oil it would use 2 courts a day. i thought the rear main was blowed out and i put it on ramps and started it and sure enought it was coming from it on the 2.3 the sending unit is on the side of the motor just right under the intake hard to see and find. i hope this is ur problem lot easier fix than a rear main. but you need to replace ur pcv and check the oil sending unit. even if you gage is working right dont mean it ant leaking.
