Before removing the valve cover, unbolt the cable from the negative terminal of the battery to prevent any electrical short circuiting. After that, take out the bolts that hold the Engine cover and then take out this cover from the valve cover. Purge and remove any hoses or wires connecting the throttle body, alternator or valve cover, pull the connectors off the ignition coils and neatly lay down the harness to one side. After doing this, take out the engine oil dipstick and, ensure that the valve cover is clean to avoid cases where particles get to the exposed cylinder head or
Camshaft/valve train assembly. After that, loosen and take out the valve cover bolts in the direction opposite to that followed while tightening them and, finally, gently raise the valve cover and the gasket off with your hands, although trying to pry with a rubber mallet gently between the cover and the cylinder head if the cover is very stuck to the head and its gasket seal is really very tight. For installation, one has to un-fasten the old gasket and than clean the surfaces to be gasketed; these are the cylinder head surface and the valve cover surface, using the breaker system cleaner and a rag. Place a new molded rubber gasket to the groove raised at the perimeter of the valve cover; use beads of RTV sealant at the joint area of the timing chain cover and the cylinder head. Fit the cover into place and install the bolts with equations to the recommended torque. Lastly, return to procedures of the removal section and connect the battery again.
