Expect roughly $6–$40 for a typical aftermarket valve cover gasket, and $15–$70 for an OEM Honda gasket or a full gasket kit with seals. Price varies by engine (2.4L 4-cylinder vs. 3.0L V6) and by retailer; labor costs are extra if you hire a shop.
Engine options in the 2005 Accord
The 2005 Honda Accord offered two common gasoline engines: a 2.4-liter inline-4 and a 3.0-liter V6. The 4-cylinder configuration generally uses a single valve cover gasket, while the V6 uses two valve covers, each with its own gasket. Depending on which engine you have, the number of gaskets you need—and therefore the total cost—will differ.
4-cylinder vs V6 gasket needs
With the 2.4L engine, you typically replace one valve cover gasket. The 3.0L V6 may require two gaskets (one for each valve cover), or a gasket kit that covers both sides. This difference shapes the overall price you’ll see at parts stores.
