adhesive has sufficient cohesive strength to hold the valve cover in place
during normal operating conditions;
b) contacting the mating surface of the valve cover with the mating
surface of the cylinder head such the continuous bead or film of adhesive
is disposed between the mating surfaces of the valve cover and the
