Post 5 nailed it. That Wagner PCV valve is the schiizznizzle. Most over the counter PCV valves are universal, in that they fit mostly nothing. After 5-7 years the manufacturers start consolidating part numbers. And believe it or not, those things were calibrated for size and spring pressure. When they start eliminating part numbers you get a PCV valve that isn't right, and you can't fix it.
Plus, the Wagner is tuneable for idle and cruise. That makes it double cool.
