Standard Ignition PCV Valve P/N:V263
$24.99
Keep crankcase pressure managed and route blow-by vapors back toward the intake with the Standard Ignition PCV Valve V263. It installs as a direct-fit replacement for the 1986-1990 Acura Legend, the 1987-1988 Sterling 825, and the 1989-1991 Sterling 827.
- One-way ventilation valve: designed to let crankcase gases flow toward the intake while limiting reverse flow back into the crankcase.
- Vacuum-metered flow: meters the flow of blow-by gases in response to manifold vacuum, drawing more at higher vacuum and less under load.
- Positive crankcase ventilation: helps route blow-by through the intended PCV path so vapors are recirculated rather than vented, supporting normal crankcase ventilation.
Over time a PCV valve can stick or clog. Signs it may need replacing include a rough or unstable idle, oil in the intake tract, or oil seepage past seals from built-up crankcase pressure. If a failed PCV valve is the cause, this replaces it; diagnose the condition first, since these symptoms can have other causes.

Frequently Asked Questions
What does this PCV valve do?
It is a one-way valve that meters the flow of crankcase blow-by gases back toward the intake based on manifold vacuum, supporting positive crankcase ventilation.
Which vehicles does the V263 fit?
It is a direct-fit replacement for the 1986-1990 Acura Legend, the 1987-1988 Sterling 825, and the 1989-1991 Sterling 827. Confirm your vehicle in the Buyer's Guide tab.
What are signs my PCV valve may need replacing?
Common signs include a rough or unstable idle, oil in the intake tract, or oil seepage past seals from crankcase pressure. Diagnose the cause first, as these can have other sources.
What part numbers does this valve interchange with?
It cross-references 17130PH7003, PCV340, 2-9340 (29340), and 12612600039.
How does a PCV valve regulate flow?
It responds to manifold vacuum, restricting flow at high vacuum near idle and allowing more flow under load, while limiting reverse flow into the crankcase.
