Valve Covers

Valve Covers Seal Your Engine's Top End

For classic car restorations or DIY repairs, Stellantis Canada is your one-stop shop for all necessary parts. Valve covers bolt to the cylinder head and contain oil that lubricates camshafts and valve train components. These stamped metal or plastic covers use gaskets that create oil-tight seals. Factory valve covers include baffles that separate oil vapor from crankcase ventilation. Quality sealing prevents external leaks and maintains proper crankcase pressure.

How Valve Covers Protect Your Engine

Your valve covers enclose the cylinder head's upper section where camshafts operate valves. Oil circulates continuously across rocker arms, lifters, and cam lobes before draining back to the pan. The cover gasket seals against the head surface using rubber, cork, or composite materials. Bolt torque specifications ensure even compression across the gasket. Breather passages in the cover route vapor into the PCV system. Some covers include integrated oil filters for direct injection systems. Mopar valve covers for vehicles like the Dodge Charger Hemi and Jeep Wrangler Pentastar use materials matched to engine heat cycles. Thread inserts in aluminum covers prevent stripped mounting holes.

Why Valve Covers Develop Leaks

Valve cover gaskets harden from heat cycling and crack along bolt holes. Gasket material shrinks with age, reducing compression. Overtightening bolts crushes gaskets and creates leak paths. Warped covers from improper installation prevent even sealing. Plastic covers crack from impact or stress around bolt bosses. Gasket sealer products fail and leak. Generic aftermarket gaskets use inferior materials that deteriorate rapidly. Crankcase pressure buildup forces oil past seals. Corrosion between mating surfaces creates uneven surfaces that gaskets cannot seal properly. Cold weather makes gaskets brittle and prone to failure.

When Valve Covers Need Attention

Replace valve cover gaskets when you notice oil leaking down the side of the engine. Fresh oil spots under your vehicle after parking indicate active leaks. Check oil level frequently if consumption increases without visible exhaust smoke. Smell of burning oil while driving suggests leakage onto hot exhaust components. Clean the engine exterior and monitor for new leaks to locate the source. Replace covers showing cracks or damage. Gasket replacement typically occurs every 60,000 to 100,000 miles. Address leaks promptly to prevent oil contamination of ignition components. Some engines require valve cover replacement rather than just gasket service. Inspect mounting bolt threads during gasket replacement. Genuine Mopar valve covers and gaskets use correct materials and fitment for reliable sealing, unlike aftermarket parts that may not match mounting patterns or withstand engine temperatures properly.
