Are you saying that in order to remove the 3 spark plugs towards the firewall i don't have to remove the upper intake manifold? Access is through the wheel well?
Do i need a valve cover gasket set together with the spark plug tube seals in order to stop the oil leak?
sorry i was thinking of a rear wheel drive engine , my mistake the intake on this engine has to come out and the plenum gasket to the intake manifold replace , the valve cover has to be replace with the seals to the spark plugs it comes as a kit
