Standard - TechSmart PCV Valve
Standard® - TechSmart™ PCV Valve
The product comes exactly as pictured. It was easy to remove the old pieces and install the new one. The only problem was the hard boot that connected the PCV tubing to the intake manifold was larger than the intake manifold connection. The boot that was already installed looked like the previous mechanic had used a rubber boot from a spark plug wire connection to a distributor cap. At first I took the new boot off and connected the old boot to the new tubing and started it up. The suction on the old boot collapsed under the vacuum. I ended up cutting up the old boot and using it like a sleeve to make the manifold connection large enough to accommodate the new hard boot. Everything works fine now and I was able to clear the "Check Engine" lite. I'm not sure why I didn't get the correct part for my car but it seems like the previous mechanic had the same problem.
