How to Change A Valve Cover Gasket on a 4-Cylinder Engine

How To Change A Valve Cover Gasket | River City Tire & Automotive

You're cruising down the road, and suddenly, you notice a distinct smell of burning oil or see that telltale puddle of oil under your car. Chances are, your 4-cylinder engine's valve cover gasket is the culprit. But don't worry, we are here to help out - here is how to change your valve cover gasket like a pro!

What is a Valve Cover Gasket?

Before we start, here are the basics. The valve cover gasket is a crucial component that seals the gap between the valve cover and the cylinder head. Its primary job is to prevent oil from leaking out of the engine while keeping dirt and debris from entering. Over time, this gasket can deteriorate, leading to oil leaks.

Tools and Materials You'll Need:

  • New valve cover gasket
  • Wrench and socket set
  • Screwdrivers
  • Ratchet and torque wrench
  • Cleaner and rags
  • Sealant (if needed)

Our Step-by-Step Repair Guide

Prepare Your Workspace

Start by ensuring you have a clean, well-lit workspace and have gathered all the necessary tools and materials.

Disconnect the Battery

For safety reasons, disconnect the vehicle's battery to prevent any electrical mishaps while working.

Locate and Remove the Valve Cover

Find the valve cover on your 4-cylinder engine and carefully remove any hoses, wires, or components that may be in the way. Then, using your wrench and socket set, loosen and remove the valve cover bolts. Keep track of their location, as they'll need to be reinstalled correctly.

Remove the Old Gasket

Gently pry off the old valve cover gasket from both the valve cover and the cylinder head. Take care not to damage the mating surfaces.

Clean and Prepare Surfaces

Thoroughly clean the valve cover and cylinder head surfaces using a cleaner and rags. Ensure there is no old gasket material or debris left behind.

Install the New Gasket

Place the new valve cover gasket onto the valve cover. If required, apply a thin layer of gasket sealant to the gasket for added security.

Reattach the Valve Cover

Carefully position the valve cover back onto the cylinder head, aligning it with the bolt holes. Hand-tighten the bolts initially and then use a torque wrench to secure them to the manufacturer's specified torque settings.

Reconnect Components

Reattach any hoses, wires, or components you removed earlier.

Reconnect the Battery

Reconnect the vehicle's battery, and you're ready for the final step.

Test for Leaks

Start the engine and carefully inspect the valve cover area for any signs of leaks. If everything looks dry and secure, you've successfully fixed the leaking valve cover gasket.
