12341-PNA-000 Engine Valve Cover Gasket
OEM‑Spec Replacement for Acura CSX RDX RSX TSX – Honda Accord Civic CR-V Element – K‑Series Engines
Product Overview
This listing is for a brand new, high-quality Engine Valve Cover Gasket, OEM part number 12341-PNA-000. This gasket is a critical sealing component designed specifically for various Acura and Honda models equipped with K‑series engines.
The valve cover gasket sits between the valve cover and the cylinder head, preventing engine oil from leaking out. Over time, heat cycles and age cause the rubber gasket to harden, crack, and lose its sealing ability, leading to oil leaks, burning oil smell on exhaust components, and low oil levels.
Replacing a worn valve cover gasket with this precision-engineered replacement restores a perfect seal, keeps your engine bay clean, prevents oil loss, and protects spark plug wells from oil contamination.
