Ok, I've had a real slow oil leak that has been dripping from the front of the oil pan and a little from the slit between the bellhousing and engine. I crawled under the car and found that one of the bolts at the front of the pan had rattled loose. So I tightened the bold Sunday night, last night when i pulled the car into the garage I noticed that the pan was leaking twice as much now. I read was reading through some other threads and someone mentioned that if the PVC system was not vented properly that it would cause oil leaks around the gasket. Does that sound right? I know my PVC system is not setup properly, because I converted over to the LS1 intake from the truck intake.

Yes, it can cause it. The crankcase HAS to be vented...somewhere, be it via a PCV system, or just vented to atmosphere via a cap on a valve cover. Without this, blowby (and there is always some) will pressurize the crankcase.
