Crown Automotive Variable Valve Control Solenoid Seals

Crown Automotive variable valve control solenoid seals (or gaskets) are crucial for preventing engine oil leaks and maintaining proper oil pressure within the VVT system, ensuring the solenoid can precisely control camshaft timing for improved engine performance, better fuel economy, and lower emissions by optimizing valve operation for different driving conditions. Without these seals, oil pressure drops, leading to rough idling, stalling, reduced power, poor fuel efficiency, check engine light, and engine noise.

Sealed Power Hydraulic Lifters

Sealed Power hydraulic lifters are precision-manufactured to maintain precise valve timing under all operating conditions. A patented constant orifice metering valve provides precise oil metering to the overhead valvetrain, and longer plungers or pistons provide increased bearing surfaces, resulting in longer lifter life. Their check valves are lightweight flat discs, allowing for higher speeds and more uniform operation than competitive lifters.
