I bought the PCV valves at a local auto parts warehouse. I initially called the local auto parts store to see if they had any. The customer rep said they had 5 in their local warehouse. They showed none were sold in the past 5 years. They did a bulk buy years ago and that's all that was left. When he gave me a price of $7.95 ea. I said I'll take all of them. I'm saving them for my customer's cars. Every once in a while I get a car in with the wrong or leaky aftermarket valve.
