Engine variants and pricing
The 2004 Honda Accord was offered with two engines, and gasket prices differ between them.
2004 Honda Accord 2.4L I4
Gasket costs vary by whether you buy a simple gasket, a full gasket kit, or an OEM-equivalent option.

- Valve cover gasket kit (includes O-rings/seals): about $30–$70
Overall, 2.4L gasket prices are typically at the lower end of the spectrum compared with the V6, though OEM parts push the price higher.

Where to buy and what affects price

Installation costs to consider
Labor costs to replace a valve cover gasket typically range from about $150 to $350, depending on labor rates, location, and whether any extra parts (like gasket seals) are needed. Some shops may discount if you’re replacing other items at the same time.
Summary
For a 2004 Honda Accord, gasket-only prices generally run from about $8 to $110 depending on engine (2.4L vs 3.0L) and OEM vs aftermarket; most drivers pay in the $15–$60 range for non-OEM and $30–$90 for OEM. Labor can significantly add to the total, so budget accordingly. Always verify part compatibility with your exact engine and VIN before purchasing.
