Correct Factory Style: PCV Valves and Breathers

This is the correct PCV valve for my 1999 Silverado 5.3 and Flex-Fuel 2002 Tahoe 5.3. Much better than the cheap big auto parts stores that sell them.

Pros
  • Helps ensure your vehicle meets emissions standards
Cons
  • Long Lead Time

rattle version.

This is the "Thunder" version, that's what came out. After 225,000 miles it was really full. Replaced with the membrane supplied with the hose. I think I read on the forum that the rattle was replaced with a neck.

Pros
  • Exhaust & Emissions
Cons
  • Zero
