Walker 590-4001 Engine Variable Valve Timing (VVT) Solenoid Filter

Walker 590-4001 VVT Solenoid Filter

Walker 590-4001 is an OE replacement engine variable valve timing solenoid filter built to keep engine oil clean before it reaches the VVT actuator. It uses a stainless steel filter element with a rubber gasket to help maintain proper oil flow and support accurate camshaft timing control in Honda and Acura applications.

Key Features

• Stainless steel filter media for oil filtration in the VVT oil circuit
• Rubber gasket material for a secure seal in the original housing or bore
• Chrome filter finish with black gasket color
• OE-style fitment for direct replacement service
• Built for high-temperature, oil-exposed engine environments
• Part number 590-4001 for service lookup and ordering

Product Details

This Walker VVT solenoid filter is designed for engines that rely on clean oil pressure to move the variable valve timing system. By filtering contaminants before they enter the solenoid actuator, it helps preserve timing response and reduce restriction in the oil feed path. It is a practical service part for Acura NSX, Acura Integra, Honda Civic, and Honda Civic del Sol applications where VVT-related oil contamination can affect drivability.

Walker 590-4001 is a direct-fit OE replacement for maintenance and repair work on the VVT oil control circuit. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• VVT solenoid screen clogging from sludge, varnish, or metal debris
• Timing-related check engine lights such as P0011 or P0014
• Delayed or inconsistent camshaft timing response
• Oil flow restriction at the solenoid actuator
• Drivability concerns tied to contaminated VVT oil passages

Installation Notes

Install 590-4001 into the original bore or housing specified for the vehicle’s VVT solenoid filter location. Clean the surrounding oil passage and inspect the solenoid area for sludge or debris before installation. For best results, verify the vehicle’s year, make, and model against the listed fitment before service.
