Product Details
Features
- True PCV valve regulates crankcase vacuum via engine manifold vacuum
- 90° 3/8" hose barb routes to intake manifold or carb base PCV port
- Fits 3/4" push-in valve cover PCV openings — grommet included
- Requires a separate breather cap on the opposite valve cover opening
Description
This billet aluminum PCV valve is designed to help manage crankcase pressure and support consistent airflow for cleaner, more reliable engine operation. Unlike a passive breather, this is a true PCV valve — it regulates crankcase vacuum using engine manifold vacuum, rather than simply venting to atmosphere.
The push-in design fits a 3/4" neck size and installs into a compatible valve cover PCV opening, with a grommet included. A 90° hose barb outlet (3/8") routes to your intake manifold or carburetor base PCV connection — confirm your hose's inside diameter matches the 3/8" barb before connecting. Because this valve manages vacuum-side ventilation only, the opposite valve cover opening on your engine still needs a separate breather cap for fresh air intake into the crankcase.
Applications
Fits universal push-in valve cover PCV openings with a 3/4" neck size. Commonly used with aftermarket valve covers and engine dress-up systems. Not matched to a specific engine or vehicle — verify your valve cover's opening style before ordering.
Installation
Push-in fitment with grommet included. Verify neck diameter (3/4"), grommet size, and valve cover opening style before installing. Confirm hose inside diameter matches the 3/8" barb before connecting. Pair with a separate breather cap on the opposite valve cover opening — this valve alone does not provide fresh air intake into the crankcase.

Engine Fitment
COMPATIBLE WITH
UNIVERSAL VALVE COVER / CRANKCASE VENTILATION APPLICATIONS
• Fits compatible push-in valve cover PCV openings, 3/4" neck size
• 90° hose barb outlet (3/8") for routing to intake manifold or carburetor base PCV connection
• Commonly used with aftermarket valve covers and engine dress-up systems
NOTES
Verify neck diameter (3/4"), grommet size, and valve cover opening style before installation. Confirm hose ID matches the 3/8" barb before connecting. This is a true PCV valve (regulates crankcase vacuum via engine manifold vacuum) — not a passive breather; the opposite valve cover opening on this engine still needs a separate breather cap for fresh air intake into the crankcase.
Q&A
Is this a breather cap or a PCV valve?
A true PCV valve — it regulates crankcase vacuum using engine manifold vacuum, rather than passively venting to atmosphere like a breather cap does.
Do I need anything else besides this PCV valve?
Yes — a separate breather cap for the opposite valve cover opening, since this valve only manages the vacuum side of crankcase ventilation and doesn't provide fresh air intake on its own.
What size valve cover opening does this PCV valve fit?
A 3/4" push-in neck size — smaller than the 1" neck size used on TSP's breather caps, so confirm which opening size your valve cover has.
What size hose does the barb fit?
3/8" inside diameter. Confirm your hose ID matches before connecting.
Does this come with a grommet?
Yes — a grommet is included.
Where does the hose from this PCV valve connect to?
To your intake manifold or carburetor base PCV connection, via the 90° 3/8" hose barb.
