so brief summary of my setup:
MS4 cam, heads, fast intake and headers through TH400 trans and 3.73 gears
currently running full syn 5w-30 and next 3k oil change is in 1500 miles. currently running a might mouse catch can and then stock pcv. the other day was cruising to a car meet and had gotten on it a few times between 4K to 5K RPMs during the 15min drive. parked and let the car sit for 2hrs. when it was time to leave and within 2min the low oil light came on. fortunately i was near a gas station and pulled in and checked the dipstick which should barely any oil on there. poured 2 qts in and after checking the dipstick it was in the middle of the hashmarks. i poured a 3rd qt in for good measure and when starting the car the light went away and the car drove fine. is this normal oil consumption with the constant high RPM?
The dipstick does tend to show lower oil than when the car is cold and oil has drained back into the pan.
I'd try to repeat the experiment. I doubt you burned 2 quarts of oil in 15 minutes. Also check for leaks and is the car running hot at all? I had a failed thermostat in the middle of a road trip (it was opening but less than optimal) and as the car got hotter through the road trip I had to add oil often. What was happening is that as it got hotter it made a leak I had on the back of the intake leak more.

car doesnt run hot, stays around 195-205* and no oil puddles when parked or blue smoke on startup or idle.
While you checking the catch can you should also grab a flashlight and have a peak into the intake through the throttle body to see if it looks wet in there. You said it's not burnig oil and if excessive oil was getting in there then it would most certainly make its way into the combustion chambers and through the exhaust. Does this car have cats?
Catch can was virtually empty. Checked behind the tb and it's damp, black sud on the backside of the tb. Also my builder recalled using sealant on the intake rocker bolts when he installed replacement cam.
correction on the catch can, i have a mike norris catch can. the way i have it currently routed is:
from driver side crosses over to passenger and has the factory y union with the passenger port then goes to the factory pcv then into the top of the catch can. the side of the catch can then goes to the one port on the tb. the other port (front) on the passenger goes directly into the port on the tb.

This doesn't sound right. It sounds like you're using the LS1 style valve covers which has a large hole on top on the driver side cover and the passenger has two 3/8 ports with one turning to the back of the car and the other towards the front. The one at the front would connect to the throttle body and the the one towards the back connects to the driver side valve cover and runs between the intake and passenger cylinder head where it connects to the port on the intake manifold. There is a PCV valve in the line just before it enters the port on the intake manifold. If you're installing catch can then leave the throttle body port as is and connect that line that goes to the intake port to the top of the Norris can and then from the side of the can you'd run a line to the intake port with an inline PCV between there.
im confused on how you have it layed out. i do have the ls1 style valve covers. the driver port and the passenger rear port connect at the factory y join. from there it goes to the pcv then top of the mike norris catch and finally to the port on the tb. the front port on the passenger goes directly to the other port on the tb. is that correct?
