Product Details

The Honda OEM K-Series Valve Cover Bolt B is a genuine factory replacement designed for select Honda and Acura K-series engines. This specialized fastener secures the valve cover to the cylinder head assembly, helping maintain proper gasket compression and a reliable seal.

Unlike a standard valve cover bolt, the Honda OEM Bolt B features an integrated upper stud that can also serve as a mounting point for engine wiring harness brackets or other factory components. Its specialized design makes it important to use the correct bolt in the correct mounting location.

Over time, original valve cover bolts can become damaged, stripped, corroded, or lost during engine maintenance. Using the correct OEM hardware is especially important when replacing a valve cover gasket, servicing the valvetrain, or rebuilding a K-series engine.

Manufactured to Honda's original equipment specifications, this genuine valve cover bolt provides factory-correct fitment and dependable fastening performance for compatible applications.

Whether you're maintaining an Acura RSX, replacing the valve cover gasket on a Civic Si, or assembling a K20/K24 engine, this genuine Honda OEM Valve Cover Bolt B is an excellent choice for restoring factory-quality engine hardware.

Installation Notes

Proper valve cover bolt installation is important for maintaining a reliable seal and preventing damage to the cylinder head cover.
Before installation, inspect the valve cover, gasket, mounting holes, and cylinder head threads for damage or contamination.
Ensure the valve cover gasket is correctly seated and that the cover is positioned properly before installing the mounting bolts.
Honda Valve Cover Bolt B (90012-PNA-003) is not interchangeable with every valve cover bolt location. Confirm the correct mounting position using the factory parts diagram.
Thread the new bolt into its mounting location by hand to prevent cross-threading.
Tighten the valve cover fasteners gradually in the sequence specified by the factory service manual, using the correct torque specification for your engine.
Avoid overtightening, as excessive torque can damage the valve cover, mounting threads, or gasket.
If the integrated upper stud is used to secure a wiring harness bracket or another factory component, reinstall that component using the correct mounting hardware.
After installation, inspect the valve cover perimeter for proper gasket seating and check for oil leaks once the engine reaches operating temperature.
