Removing PCV valve on 4.7

[jminz]

I've recently replaced the valve cover gasket and am also experiencing oil wetness on the upper intake manifold bolts. I'm assuming bad intake manifold gasket. That being said I thought it'd be a good idea to replace the pcv valve. However it appears to be seized. Is pb blaster safe to use in this area? Or any other suggestions on removing it?

Yeah, I replaced mine. Get a big wrench slow and steady it will break lose

Did you use a lubricant to break it loose?

I used a quick spray of wd40 blue torch... steady hard pressure with good leverage on a big wrench and it broke loose.

Slow and use a long wrench. The threads have a sealant on it so it will be a little more difficult.
