Honda Civic Engine Cylinder Head Gasket Kits

Honda Civic Engine cylinder head gasket kits

Engine cylinder head gasket kits for the Honda Civic start at low prices and include everything needed to reseal the head to the block. We stock multiple kits from top OE-quality brands. The head gasket creates a pressure-tight seal between the cylinder head and engine block, keeping combustion gases, coolant, and oil in their separate passages. When it fails, the engine can overheat, lose compression, or mix fluids — causing rapid and expensive damage.

Signs your Honda Civic needs a new engine cylinder head gasket kit

  • White or sweet-smelling smoke from the exhaust, especially at startup, indicating coolant burning inside the combustion chamber
  • Coolant level drops repeatedly with no visible external leak under the vehicle or around hoses
  • Milky, frothy oil on the dipstick or inside the oil filler cap, caused by coolant mixing into the engine oil
  • Engine overheating consistently or temperature gauge spiking, often because combustion gases are pressurizing the cooling system
  • Bubbles visible in the coolant reservoir while the engine is running, a sign of combustion gas entering the cooling passages
  • Noticeable loss of power, rough idle, or misfires on one or more cylinders due to compression escaping past the failed gasket

Which engine cylinder head gasket kit should you buy for your Honda Civic?

The most important decision is choosing between a standard replacement kit and an upgraded multi-layer steel (MLS) gasket kit, since the two suit different engine conditions and machining histories. You also need to confirm whether the kit covers just the head gasket or includes all associated seals, o-rings, and cam seals needed for a complete job. Buying a full kit rather than the head gasket alone typically saves time and prevents repeat disassembly for a forgotten seal.

Standard Replacement (OEM-style composite or fiber gasket)
Best for
Stock engines with a freshly cleaned but unmachined head; budget-focused rebuilds
What you get
A gasket that matches original factory material and thickness; straightforward fitment with no surface prep beyond cleaning
Multi-Layer Steel (MLS) Kit
Best for
Engines with a resurfaced or machined head; high-mileage rebuilds; engines prone to overheating distortion
What you get
A durable steel-layered gasket that tolerates minor surface imperfections better and handles higher cylinder pressures
Complete Head Gasket Kit (full top-end set)
Best for
Anyone doing a thorough rebuild who wants every seal in one box
What you get
Head gasket plus valve cover gasket, intake and exhaust manifold gaskets, cam seals, and all related o-rings for the upper engine
Oversize / Retorque Kit
Best for
Engines with a bored or lightly over-decked block where standard thickness changes compression ratio
What you get
A gasket with adjusted compressed thickness or bore size to restore proper compression after machine work

Replacing the head gasket on a Honda Civic requires draining the cooling system, removing the intake manifold, valve cover, timing components, and all hardware securing the cylinder head before the head itself can be lifted off. Once the old gasket is removed, both mating surfaces must be thoroughly cleaned and inspected for flatness before the new gasket and head are installed. Head bolts should be tightened in the manufacturer-specified sequence and method — typically in multiple stages — to ensure even clamping force across the gasket surface.

Frequently asked questions

How much does it cost to replace engine cylinder head gasket kits on a Honda Civic?
Parts alone start at low prices for a Honda Civic head gasket kit. Total repair cost depends heavily on labor, since the job requires removing the cylinder head, which is several hours of work at a shop. Additional costs can include head resurfacing, new head bolts, and coolant flush, so budget well beyond the kit price alone.
Can I drive my Honda Civic with a blown head gasket?
No. Driving with a blown head gasket on a Honda Civic risks severe engine damage within a short distance. Coolant entering the combustion chamber can hydrolock the engine, and oil contaminated with coolant loses its lubricating ability rapidly. Continued overheating can warp or crack the cylinder head, turning a gasket replacement into a full head or engine replacement.
Do I need to resurface the cylinder head when replacing the head gasket on a Honda Civic?
In most cases, yes. Any Honda Civic that overheated is likely to have some warping of the cylinder head surface. A machine shop can measure flatness and resurface if needed. Skipping this step and installing a new gasket on a warped head almost guarantees the new gasket will fail again, often quickly.
Should I replace the head bolts when installing a new head gasket kit on a Honda Civic?
If the Honda Civic uses torque-to-yield (TTY) head bolts, yes — they must be replaced. TTY bolts stretch permanently during tightening and cannot be reused reliably. Standard hex head bolts can sometimes be reused if they are undamaged and within spec, but most professional rebuilds replace them anyway. Check your kit description and service documentation for guidance.
What causes a head gasket to fail on a Honda Civic?
The most common cause on a Honda Civic is overheating, which warps the cylinder head and crushes or erodes the gasket unevenly. Age and high mileage cause material degradation over time. Pre-ignition or detonation adds extreme pressure spikes that can breach the gasket between cylinder bores. Some engines also have known design vulnerabilities that make gasket failure more common.
How long does a head gasket replacement take on a Honda Civic?
The job on a Honda Civic typically takes between 6 and 12 hours for an experienced technician, depending on engine layout and accessibility. Front-wheel-drive transverse engines and vehicles with overhead camshafts generally take longer due to the additional components that must be removed. Head resurfacing at a machine shop adds extra time if the vehicle cannot be driven.
