Default Compression test recommended

What exactly are your symptoms? The first thing that I would recommend is getting a compression test done. Any shop with a quality OBD device can perform the compression test, in diagnostic mode. The reasoning is; what is pushing the oil out through PCV?

The Saleen supercharged 5.4's aren't running a lot of boost. Meaning there isn't enough pressure being generated to push oil back through the PCV system. A catch can is cheap enough, it would be installed on the drivers side, though. I would get the compression check done, first. Please let us know how you make out.
