The PCV valve on a 1995 Buick Park Avenue is located on the top of the valve cover. Twist the valve and pull to remove and replace it.
The oil filter on the 1995 Buick Park Avenue is located on the driver's side in the engine compartment. The filter is close to the firewall on the driver's side.
I believe they are 3/16"
The Buick Park Avenue Started In 1991
How do I change the head gasket on a 1995 Park Avenue. and what are the specs.

By disassembling the engine. Not a DIY job.
