This thread mentions possible problem of PCV hose getting kinked when you close the hood:

If you still had the car I would suggest putting a dollop of shaving cream on top of that PCV hose and closing the hood. If you see a smeary mess on your hood liner you know the hood touched the hose and pushed it. The shave cream should be easy to clean off.
my guess is this car may work just fine in the shop with the hood open.
More posts commenting how the LT2 basically touches the hood liner when closed, and you have to modify the PCV fitting to prevent kinking of the hose:
