Factory Outlet Billet Aluminum PCV Valve Push-In 3/4 Neck Universal Black

Overview

This billet aluminum push-in PCV valve manages crankcase pressure and supports consistent airflow for reliable engine operation. Unlike a passive breather, it is a true PCV valve that regulates crankcase vacuum using engine manifold vacuum rather than simply venting to the atmosphere.

Key Specifications

Fitment & Compatibility

This PCV valve is a universal fit for push-in valve cover PCV openings with a 3/4" neck size. It is not matched to a specific engine or vehicle and is commonly used with aftermarket valve covers and engine dress-up systems.

• Fits compatible push-in valve cover PCV openings, 3/4" neck size
• 90° hose barb outlet (3/8") routes to intake manifold or carburetor base PCV connection
• Not vehicle-specific — verify your valve cover's opening style before ordering

Installation & Use Context

The push-in design installs into a compatible valve cover PCV opening with a grommet included. The 90° 3/8" hose barb routes to your intake manifold or carburetor base PCV connection.

• Verify neck diameter (3/4"), grommet size, and valve cover opening style before installing
• Confirm the hose inside diameter matches the 3/8" barb before connecting
• This valve manages only the vacuum side of crankcase ventilation — a separate breather cap is required on the opposite valve cover opening to provide fresh air intake into the crankcase
• The 3/4" push-in neck size is smaller than the 1" neck size used on dedicated breather caps, so confirm which opening size your valve cover has

Key Features

• Billet aluminum construction rated to handle engine bay heat for long-term durability
• Push-in fitment for 3/4" neck size valve cover PCV openings, with grommet included
• True PCV valve regulates crankcase vacuum via engine manifold vacuum rather than passively venting like a breather cap
• 90° hose barb outlet with 3/8" inlet routes to intake manifold or carburetor base PCV connection
• Universal fit for aftermarket valve covers and engine dress-up systems; requires a separate breather cap on the opposite opening for fresh air intake

Frequently Asked Questions

What valve cover opening does this PCV valve fit?
This is a universal push-in PCV valve that fits a 3/4" neck size in compatible valve cover PCV openings. It is not matched to a specific engine or vehicle, so verify your valve cover's opening style and neck diameter before ordering.

Is this a breather cap or a true PCV valve?
This is a true PCV valve that regulates crankcase vacuum using engine manifold vacuum, rather than passively venting to the atmosphere like a breather cap does. It manages only the vacuum side of crankcase ventilation.

Do I need anything besides this PCV valve?
Yes — pair it with a separate breather cap on the opposite valve cover opening. This valve only manages the vacuum side of crankcase ventilation and does not provide fresh air intake into the crankcase on its own.

How does this neck size compare to standard breather caps?
This PCV valve uses a 3/4" push-in neck size, which is smaller than the 1" neck size used on many aftermarket breather caps. Confirm which opening size your valve cover has before installing.

What hose size does the barb fit and where does it connect?
The 90° hose barb has a 3/8" inside diameter. Route it to your intake manifold or carburetor base PCV connection, and confirm your hose's inside diameter matches the 3/8" barb before connecting.
