Pcv is rattling

I worked on it today,did a compression test.HOT.all cyl did 152 -156-psi with s/p out ign grnded and throttle w/o..pretty even across the board...no oil in cyl.[new mtr]..put a vac gaude on it,pulled 17.5 after adjusting idle screws and when I first started with gauge the needle was vibrating 4 inches till I snmoothed it out with the adjustment..then while I had the gauge on it and while it was vibrating wildly I pinched off the pcv hose[brand new] and the wild swing of the needle went away...I took pics of the plugs ..ill post them here as soon as I get em processed..how do they look?????
