Product Details

Features

  • Billet aluminum body with polished finish and finned oval top style
  • Built-in 90° PCV valve with 3/8" hose barb for direct PCV hose routing
  • Fits 1" push-in openings on compatible Chevrolet, Ford, Chrysler valve covers
  • One-piece design combines finned oval styling with PCV function

Description

The Finned Aluminum Oval Push-In Breather with PCV Valve – Polished combines a finned oval dress-up cap with a built-in PCV valve, so crankcase ventilation and PCV routing come from one valve cover opening. Billet aluminum construction with a polished finish and finned oval top style gives the engine bay a distinct look, while the integrated 90° PCV valve with a 3/8" hose barb inlet supports proper PCV hose routing.

This unit is sized to a 1" neck and pushes into compatible valve cover ventilation openings — neck or inlet sizing must match the valve cover grommet, hose, or opening style for proper fitment. It's commonly used on universal hot rod, muscle car, truck, and performance builds, including Chevrolet, Ford, and Chrysler V8 applications with matching valve cover openings.

Before installation, verify neck diameter, grommet size, PCV routing, and valve cover opening style, along with clearance around the rocker cover, coil, and hood.


Applications
Fits compatible push-in valve cover ventilation openings sized to a 1" neck. Commonly used on universal hot rod, muscle car, and truck builds, including Chevrolet, Ford, and Chrysler V8 engines with matching valve cover openings.

Billet aluminum body with a polished finish and finned oval top style — length 4", width 2 3/8", height 2 3/4". Built-in PCV valve is set at 90° with a 3/8" hose barb inlet. No grommet included, so the valve cover opening must accept the push-in neck directly.
