How to Replace Valve Cover Gasket in Honda Cars

by Contributing Writer

The valve cover gasket on a Honda car is the seal that surrounds the inner edge of the valve cover. The valve cover is the metal plate that covers the valves. Every Honda car vehicle has valves and valve covers, but the location of the valve cover will vary from model to model. The bolts that secure the valve cover to the engine will need to be torqued to the specifications for that specific Honda car model once the valve cover has been replaced. This is not a difficult job to complete, but you will need to have a complete knowledge of the top end of the Honda car engine.

Removal

Remove the spark plug wires from the valve cover by twisting them from side to side while pulling on the boot. Set them aside.

Use pliers to squeeze the clip on the end of the vacuum line that runs from the air intake duct to the valve cover and slide the clip back. Slide the vacuum line off of the valve cover.

Remove the Positive Crankcase Ventilation (PCV) valve from the valve cover, with the vacuum line still attached, by twisting then pulling it out. This is the plastic elbow that is in the center of the valve cover. Set it aside.

Use a ratchet, extension and 10 mm socket to remove the bolt that attaches the ground wire to the front of the valve cover. Remove the four valve cover bolts, washers and rubber washers.

Place the screwdriver between the valve cover and the head of the engine and twist it to pry up the valve cover. Lift the valve cover off of the engine.

Remove the valve cover gasket and spark plug tube seals. Note how the spark plug tube seals are inserted into the valve cover.
