Hi All,

87 civic HB, D16A3, 145k/mi, smokes (apparently only at idle). Compression test (dry) is 150+ across the board and vacuum test is green and steady.

Engine winds out nicely at WOT and as it sits it seems to smoke more and more so I'm thinking the vacuum at idle is sucking oil through the valve seals... anything else I should check?
 
Could be piston rings, pcv if the car even has one, valve seals
