If you got a lot of miles try the Seafoam internal cleaning. That stuff will break/remove all the junk in the combustion system. Some oils have wax in them and other stuff that will gum up the rings and cause your blow-by issue.
ICV would never cause positive crankcase pressure only gasses getting by the piston rings
