Turns out I'm not insane. A bunch of the LS guys do this relocation all the time with almost the exact same sensor because some aftermarket intakes don't have the provision for the sensor. Some have made custom billet blocks with a barb running to them, but others have just run a hose with some clamps to it! I'm going to tee off the vacuum for the catch can and try that to start with, just in case it doesn't work properly. That way I can just temporarily plug the stock pcv vacuum intake and route a catch can temporary to see if it works first before I go drilling holes!
Didn't realize this, but I forgot that the L67s have MAP sensors fed simply by vacuum. Same sensor, just connected externally like I'm planning!
If this works, that means anyone with a L26/L36 can easily adapt their pcv systems to run a catch can without running a breather, and without re-routing their entire pcv system! (plus could be easily reverted back) This method might be adaptable to the L67 but I'd have to do more research first.
