PCV plumbing
does anyone out there have a diagram of an pcv system on a gs corvette c6. I just rebuilt my engine in my vette and didn't take pictures of the pcv vacuum system and don't how to route the plumbing now that I have an supercharger. if anyone could shed some light or provide a pic of their engine without the valve covers one it so that I can see the routing of the pcv system I would be greatly appreciative. If there is someone with pic of a supercharged c6 with catch can with the routing that would be awesome also.

Here is how my GS / wet-sump is routed ... I am using a Magnuson Heartbeat SC and a MightyMouse catch can (without the filter on top of the catch can).

you need to move to a place you can put the pressure release back on the can, or at a minimum connect the driver holley valve cover to the air bridge and cap the valley

I need a source of fresh air into the system, so I take the clean fresh air from upstream of the throttle body and route it into the crankcase valley cover (blue line).
As far as needing a 'pressure release' (MightyMouse catch can top filter), I don't think my engine ever see's positive pressure (blow-by) in the crankcase ... Am I wrong?

the valley can be used for fresh air supply in this configuration, not venting. same for the driver (oem) cover, no good for venting.
the only one good for venting is the passenger cover, which is why it hooks to the can, but with the vent disabled you have little to no venting through the cans pcv or the stock pcv to handle stock hp, let alone additional power. it can easily result in main seal failure, dipstick popping etc.
since your driver cover is aftermarket you could at least run that to the air bridge vs. the valley, but the better thing to do would be to run the system as designed.

Thank's for the advice ... The only reason I removed the top cap filter on the MightyMouse catch can was because it was too tall and I could close my OEM hood.
Where the catch can is mounted now was about the only place that it could be [easily] mounted in my wet-sump engine compartment ... It can't be mounted lower because of interference with the coolant hoses below it (that's down as far as it will go).
