Function And Description

The valve cover protects the camshafts, rocker arms and valve train while keeping engine oil contained in the top end. It also provides mounting points for ignition coils, breather hoses and the PCV (positive crankcase ventilation) system. A secure seal between the valve cover and cylinder head is essential to prevent oil leaks, contamination and pressure loss in the crankcase ventilation system.

Replacement Procedure (Overview)

• Work On A Cold Engine: Allow the engine to cool before starting work.
• Remove Obstructions: Detach air intake components, ignition coils and hoses that obstruct access to the cover.
• Remove Cover Bolts: Loosen bolts in a cross pattern and remove the valve cover.
• Clean Mating Surfaces: Carefully clean the cylinder head and cover mating surfaces; remove old gasket material without scratching.
• Replace Gasket And Seals: Fit a new gasket and any damaged grommets or seals.
• Refit And Torque: Reinstall the cover and tighten bolts to the manufacturer’s torque specification and sequence.
• Reconnect Components: Reinstall ignition coils, hoses and intake components. Start the engine and check for leaks.

Installation Recommendations

• Always Use A New Gasket: Replace the valve cover gasket and any worn bolt seals or washers when installing the cover.
• Clean Surfaces Thoroughly: Ensure both mating surfaces are clean and dry to achieve a reliable seal.
• Follow Torque And Sequence: Tighten bolts in the correct sequence and to the manufacturer’s torque values to avoid warping or leaks.
• Inspect Related Parts: Check the PCV valve, ignition coil boots and mounting studs; replace if cracked or degraded.
• Professional Tools: Use proper tools and, for best results, a torque wrench. If uncertain, have the job performed by a qualified technician.

Why The Part Commonly Fails

• Gasket Deterioration: Rubber and composite gaskets harden, shrink or crack with age and heat, leading to oil leaks.
• Overheating And Warpage: Excessive engine temperatures or improper bolt tightening can warp the cover, breaking the seal.
• Cracks Or Impact Damage: Physical damage from tools or debris can crack the cover, especially around mounting points.
• PCV System Faults: A blocked or failed PCV valve can create excess crankcase pressure, forcing oil past the gasket.
• Worn Mounting Hardware: Stripped threads, damaged studs or missing washers reduce clamping force and lead to leaks.

Signs To Watch For

• Visible Oil Leaks Around The Valve Cover
• Oil On Ignition Coils Or Spark Plug Wells Causing Misfires
• Burning Oil Smell Or Smoke From Engine Bay
• Low Oil Level Without External Leak Elsewhere

Why This Part Fails Most Often

Valve covers commonly fail due to age-related deterioration of the gasket and cover material under continuous heat cycles, chemical exposure to engine oil and additives, and mechanical stress from vibration. A blocked or malfunctioning PCV/pressure valve can raise crankcase pressure and accelerate leakage. Timely replacement and inspection during routine maintenance prevents oil leaks, engine bay contamination, and related ignition issues.
