What is the Valve Cover all about?

Valve Cover – also called a rocker cover – is a vital component of the engine; it’s a plastic or metal component that is bolted to the top of the cylinder head. The gap between the valve cover and the cylinder head is sealed by a valve cover gasket. The whole setup keeps oil inside the engine, which is important to the engine’s overall health and performance.

Keep in mind:

  • Your valve cover gasket and seals will naturally break down over time.
  • The majority of today's valve cover gaskets and seals last up to 60,000 miles provided that oil changes aren't delayed.
  • When a check engine light on it might mean there's an oil leak in the valve cover gasket, hence oil may have caused damage to your ignition.

How it's done:

  • Open the hood and take off the engine cover.
  • Remove valve cover bolts.
  • Check your manual's recommended torque sequence.
  • Part of the valve cover can be sealed by silicone RTV; if so remove silicone RTV entirely.
  • Perform this procedure backwards.
  • Finish the repair with a test drive and check your oil dipstick to ensure appropriate oil level.

What common symptoms indicate you may need to replace the Valve Cover?

  • Engine runs rough or unevenly
  • A decrease in your engine's horse power
  • The smell of burning oil
  • Dirt on your valve cover
  • Oil dripping under the vehicles

How important is this service?

Loose or broken valve covers cause oil to leak out and it's a vital service to avoid extreme engine wear. Without enough oil, there’s excess friction between the fast moving parts and significant break down of parts, leading to potentially expensive damage.
