Honda Accord Crosstour Engine Valve Cover Gaskets
Honda Accord Crosstour Engine valve cover gaskets
Engine valve cover gaskets for your Honda Accord Crosstour start at $13.95, and AutoBuffy stocks 3 options from Elring. The valve cover gasket seals the top of the engine, keeping oil inside while blocking dirt and debris out. When it fails, oil leaks onto hot engine components, creating smoke, odors, and potential engine damage if ignored.
Signs your Honda Accord Crosstour needs a new engine valve cover gasket
- Visible oil residue or a crusty brown buildup along the seam where the valve cover meets the cylinder head
- Burning oil smell from the engine bay, caused by oil dripping onto the exhaust manifold or other hot surfaces
- Low oil level warnings or frequent need to top off oil without any obvious external puddles under the vehicle
- Rough idle or misfires if oil has leaked into spark plug tube seals and contaminated one or more plug wells
- Smoke rising from the engine compartment, particularly after the engine reaches operating temperature
- Oil residue or fouling on the outside of spark plug boots, indicating the tube seals within the gasket set have also failed
Which engine valve cover gasket should you buy for your Honda Accord Crosstour?
The most important decision is material — rubber, cork, or cork-rubber composite — because each handles heat cycling and compression differently across engine designs. You also need to confirm whether your Honda Accord Crosstour requires a single gasket or a full kit that includes spark plug tube seals and grommets, since replacing only the main gasket and leaving worn tube seals often leads to repeat leaks.
OEM-equivalent molded rubber
Best for
Daily drivers and owners who want a direct, leak-free fit with no trimming
What you get
Pre-formed profile matched to the cylinder head, consistent compression, long service life
Cork or cork-rubber composite
Best for
Older engines originally sealed with cork or budget-conscious repairs on low-mileage vehicles
What you get
Traditional sealing material, compresses to fill minor surface irregularities, lower upfront cost
Full gasket kit with tube seals and grommets
Best for
Engines showing oil in plug wells or any Honda Accord Crosstour with high mileage
What you get
Complete set that addresses all common leak points in one repair, prevents repeat jobs
Performance or silicone gasket
Best for
Modified engines, forced-induction builds, or extreme heat environments
What you get
Superior heat and chemical resistance, reusable on some designs, holds a tighter seal under high thermal stress

Replacing an engine valve cover gasket on a Honda Accord Crosstour
Moderate⏱ 1–3 hoursSocket set and ratchet (metric and standard)Torque wrenchPlastic scraper or gasket removal toolBrake cleaner or engine degreaserRTV silicone sealant (if required by gasket instructions)
Remove the old valve cover after disconnecting any ignition coils, breather hoses, or engine covers blocking access, then thoroughly clean all sealing surfaces with a plastic scraper and degreaser — no gasket adhesive or old sealant should remain. Set the new gasket in place, apply RTV only at the corners if specified, reinstall the cover, and tighten the bolts in a cross pattern to the manufacturer's recommended snug specification without overtightening, which can warp the cover or squeeze the gasket unevenly. Allow any RTV to cure before starting the engine, then check for leaks after the first heat cycle.
Frequently asked questions
How much does it cost to replace engine valve cover gaskets on a Honda Accord Crosstour?
Parts start at $13.95 for a Honda Accord Crosstour valve cover gasket at AutoBuffy. DIY total cost is typically just the gasket and a tube of RTV sealant if required. Professional labor adds roughly one to three hours of shop time depending on how accessible the valve cover is on your specific engine layout.
Is it safe to drive a Honda Accord Crosstour with a leaking valve cover gasket?
A minor seep may allow limited driving, but it is not safe to ignore. Oil dripping onto a hot exhaust manifold creates a fire and smoke hazard. If oil reaches plug wells and causes misfires, continued driving can damage the catalytic converter. Address the leak as soon as it is confirmed to avoid compounding repairs.
Do I need RTV sealant when replacing a valve cover gasket on a Honda Accord Crosstour?
It depends on the gasket design and engine. Many modern molded rubber gaskets seal without RTV, but most manufacturers require a small bead of RTV at the corners where the camshaft bearing caps or timing cover meet the cylinder head. Always follow the gasket maker's instructions and consult your Honda Accord Crosstour service manual for the correct application points.
How long do engine valve cover gaskets last on a Honda Accord Crosstour?
Most valve cover gaskets last somewhere between 50,000 and 100,000 miles, though heat cycling, oil type, and maintenance habits all affect lifespan. Engines that run hot, use conventional oil changed infrequently, or sit in high-mileage service tend to harden and crack gaskets earlier. Inspect the gasket area during routine oil changes to catch seeps early.
Can a bad valve cover gasket cause my Honda Accord Crosstour to burn oil or fail an emissions test?
A leaking valve cover gasket does not directly cause the engine to consume oil internally, but the external leak lowers the oil level, which can cause elevated oil consumption symptoms. Oil contaminating plug wells can trigger misfires that fail an emissions test. Fixing the gasket before a smog check is the right first step if leaks are present.
Does replacing the valve cover gasket on a Honda Accord Crosstour require removing other components?
On many engines the valve cover is accessible with basic hand tools, but some Honda Accord Crosstour designs route intake ducting, ignition coils, engine covers, or even coolant hoses directly over the valve cover. Budget extra time to identify and safely remove any obstructions before starting. Taking photos before disassembly helps ensure correct reassembly.
