Default Very strange question regarding catch can?

I took a hollowed PCV valve and put it in the driver side valve cover by the back of the cowl.I ran a line to a 3 barbed TEE and the attached the TEE to the pass. side vavle cover.

Next I ran the other side of the TEE to my catch can and then the otherside of the catch can over to the PCV valve/hose going into my intake

I now seem to see about a 6PSI drop in oil PSI?
Is this normal,I went from 41 PSI to 35 PSI at idle?

Is is pulling too much vacum and lugging the motor down?
I might go back to my open breathers,This is strange?
Anyone have any thoughts?

PS
I have the truck PCV,Should I replace it with a regular PCV valve as to let alittle more vacum to take place?

My PCV system is stock 2001 with the AMW kit. (did replace the pcv valve couple months back)

The AMW kit basically adds a hose from the tb side of the pcv valve to the can, then from the can back to the tb neck on the intake.
