I have a 2002 outback with a 2.5 liter engine. I purchased a replacement PCV valve, but the new valve did not match the valve I removed. The engine is a four valve engine, not a six valve like the 3.0 liter engine. However, the PCV valve I removed is the valve for the 3.0 liter engine, but the engine, according to the VIN is a 2.5 liter engine. Anybody experienced this issue before?
