    Hi klemme8181,

    The valve on our project vehicle wasn't riveted, and the GM factory service information doesn't mention anything about a riveted bracket, either. But, if you're sure that's the PCV valve you're looking at (in the front cylinder bank valve cover), you'll have to drill out the rivet to get the valve out.
