Smoking Out Of Drivers Side Exhaust

Noticed my car is smoking blue out of the drivers side exhaust, only after when its warmed up and hot, i replaced the pcv valve, and intake manifold gasket, and it still did the same thing, i took a compression test and found all cylinders on drivers side as follows: 145 145 155 140, im running out of ideas to think, i have a pair of brand new brodix IK200 Heads on there, i have no clue what to think??? any help would be appreciated, btw car still runs really strong!!!
