Description:
Universal PCV (Positive Crankcase Ventilation) valve for classic V8 engines. The PCV system pulls blow-by gases out of the crankcase and routes them back through the intake to be re-burned — essential for reducing oil consumption, sludge buildup, and emissions while keeping crankcase pressure in check.
Standard fitment in any 1.25" valve cover grommet. Replace your PCV valve when it stops rattling (stuck shut) or when oil consumption climbs unexplained.
Specifications:
- Type: Standard PCV valve
- Fits: 3/4" ID grommet (1.25" valve cover hole)
- Application: Universal V8 — Small Block Chevy, Big Block Chevy, Small Block Ford, etc.
