Honda genuine valve cover gasket 12341-plc-000 for Honda Civic 7

Genuine Honda OEM valve cover gasket 12341-PLC-000 designed for petrol engines from the D-series (D14/D16/D17) used in Civic, FR-V and Stream. Made from durable, heat- and oil-resistant rubber, it restores proper sealing of the valve cover and helps eliminate oil leaks from the top of the engine.

Honda-branded valve cover gaskets offer significantly better quality than most aftermarket replacements – they keep their elasticity for longer, are less prone to hardening and provide more stable long-term sealing of the cylinder head and cover.

Why choose a genuine Honda valve cover gasket?

• Honda OEM part – exact fit for the cylinder head and valve cover
• High-quality rubber – resistant to engine oil and high temperatures
• Stable sealing – reduced risk of oil leaks and “sweating” around the cover
• Less hassle during service – correct profile for factory grooves in the cover
• Matched to D-series engines – designed specifically for D14/D16/D17 applications

When should the valve cover gasket be replaced?

Typical symptoms of a worn or incorrectly fitted valve cover gasket:

• oil traces around the joint between the cover and the cylinder head,
• oil running down the front of the engine or towards the exhaust manifold,
• smell of burnt oil coming from the engine bay,
• oil present around spark plug wells.

When replacing the valve cover gasket, it is also recommended to check the condition of the cover itself (cracks, deformation) and the seals around the spark plug tubes.

FAQ – Honda valve cover gasket 12341-PLC-000

Does this gasket fit all seventh-generation Civics?
No. The 12341-PLC-000 gasket fits petrol engines from the D-series (D14Z6, D16V1, D16W7, D17A8, D17A9). It is not intended for 2.0 engines with the K20 unit.

How is a genuine Honda gasket different from a cheap aftermarket one?
The Honda OEM valve cover gasket is made from high-quality rubber that is more resistant to oil and temperature. It keeps its flexibility and sealing properties for a longer time, which helps to prevent oil leaks compared to low-cost aftermarket parts.

Do I need to use sealant when installing the gasket?
In most cases only a small amount of factory-type sealant is used in critical areas (for example at the corners of the cylinder head), according to the Honda workshop manual. Excessive sealant application can be harmful to the engine.

Should I replace the spark plug tube seals at the same time?
Yes, if there is oil in the spark plug wells it is recommended to replace the spark plug tube seals together with the valve cover gasket to restore full sealing of the upper part of the engine.

Can you confirm fitment using the VIN?
Yes. If you are unsure whether 12341-PLC-000 is correct for your engine, please provide the VIN so the part can be verified in the Honda EPC catalogue.
