Starting at $24.95, AutoBuffy stocks 2 Engine Variable Valve Timing (VVT) Solenoid Gaskets from SKP and URO. This small seal sits between the VVT solenoid and the cylinder head, preventing oil leaks at that junction. When it fails, oil pressure to the VVT system drops, causing rough idle, poor fuel economy, and check engine codes that won't clear until the gasket is replaced.
The most important buying decision is fitment accuracy — VVT solenoid gaskets are highly application-specific in size, thickness, and material because oil pressure and temperature demands vary by engine design. You also need to decide whether to replace only the gasket or purchase a solenoid-and-gasket kit, since a leaking gasket often signals the solenoid itself should be inspected at the same time.
| Option | Best for | What you get |
|---|---|---|
| OEM-equivalent rubber gasket | Standard maintenance replacement with a factory-matched fit | Correct thickness and durometer to seal at rated oil pressure; drop-in fitment |
| Solenoid and gasket kit | High-mileage engines or when the solenoid is also suspect | New solenoid plus a pre-matched gasket in one box, eliminating a second R&R if the solenoid fails shortly after |
| Intake-side gasket | Engines with separate intake and exhaust cam phasers | Seals the intake camshaft VVT solenoid; confirm bank and side before ordering |
| Exhaust-side gasket | Engines with independent exhaust cam phaser control | Seals the exhaust camshaft VVT solenoid; often a different shape or thickness than the intake-side unit |
Remove the electrical connector from the VVT solenoid, then unbolt the solenoid from the cylinder head and pull it straight out, being ready for a small amount of oil to drain from the port. Thoroughly clean both the solenoid base and the cylinder head seating surface with parts cleaner, install the new gasket dry or with a light film of clean engine oil as directed by the gasket manufacturer, then reinstall the solenoid and snug the bolt to a firm but gentle torque — over-tightening is the most common mistake. Reconnect the harness, start the engine, and check for leaks before clearing any stored codes.
