Burning oil at high RPM

Okay, so i started rebuilding my engine, just because it finally spun a bearing, 
But i was looking at the pcv valve, and its just a vacuum line that goes from the valve cover, to the intake right before the supercharger. So could the supercharger be pulling too much of a vacuum and suck oil in, and force it to the engine?
Should i relocate it to the stock location, or should i just get an oil catch can?

My 2020 V6 w/8k is also "atomizing" sythetic....
With what's going on, you might want to consider installing a crankcase evacuation system, something more positive to pull crankcase pressure out. With the pressure you're building up, the small amount of blue smoke and popping the PCV valve out could be the least of your problems. You can eventually pop an oil seal, giving you nice leaks, plus excessive crankcase pressure can hurt your ring to cylinder wall sealing capabilities. Kits like: this one, has the exhaust drawing the pressure and fumes out. Yeah it's more work than slapping in a valve cover breather or two, but your engine is telling you it isn't happy with having only passive venting.
I would have just bought an SS if I knew mine was going to have the problems I am having. Part of the problem is that it doesnt have an oil cooler. I heard that the valve duration is higher and its problem is valve blow by. At 7640 miles I didnt think that oil consumption was going to be an issue. Now cars are mega more expensive to buy. I bought the 6 because I am on a fixed income, and the insurance and payment is affordable for me.$335 a mo @ 2.54% and $99 a month for full coverage.
An SS is $590 for a used one and $180 a month for insurance on a car I just drive on weekends. Now that gas is very high I need that 6th gear for highway 25 to 28 mpg. However all I do is drive it on my childhood back roads where my only fear is hitting a deer. (No tickets since 2016).
So is it this little Supercharger doing it or would any V6 or V8 have some blow by due to the hard charging 6 speed fun I have on weekends? I know it isnt leaking. No dripping under the car. I just dont want to cover my exhaust with sludge and burn out the O2 sensors...plus I have 2 cat converters to get clogged.
Am I being a worry wart? Or should I just lay off the throttle and just enjoy it for what it is and stop ******* it to get my adrenaline going? (Which is what I bought it for).
Frustrated.
