Standard Ignition V237 PCV Valve

PCV Valve for Ford and Mercury Applications

The Standard Ignition V237 PCV Valve is a direct replacement crankcase ventilation valve for select Ford and Mercury vehicles from the mid-1980s through 1989. It is built with a straight nipple orientation, two hose connectors, and 3/8 in. (10 mm) hose sizing for a straightforward service replacement.

How It Works

This PCV valve helps manage crankcase vapors by routing them back into the engine intake stream, supporting emission control system operation. Standard Ignition designs its emission components to address common OE failure patterns, and the V237 is manufactured with quality control maintained through the process from component parts to finished product. This part cross-references AP Exhaust 28015 for the same application.

Common Problems It Can Address

• Rough idle caused by a sticking or restricted PCV valve
• Excess crankcase pressure from poor ventilation flow
• Oil vapor buildup in the crankcase ventilation system
• Emission system faults related to worn PCV hardware
• Vacuum routing issues on select Ford Mustang and Mercury Topaz applications

Installation Notes

Verify hose size and nipple orientation before installation. The V237 uses a straight nipple layout with 3/8 in. and 10 mm hose sizing, so confirm the existing hoses match the valve connections on your Ford Ranger, Thunderbird, Aerostar, Mustang, Tempo, Cougar, or Topaz application. Inspect the hoses and surrounding vacuum lines for wear before replacing the valve.

Quality Assurance

Standard Ignition manufactures emission control components with in-process quality control from componentry through final assembly. The V237 is built as a service replacement PCV valve for the listed Ford and Mercury applications.
