First, you need to remove the fuel injector sight shield, disconnect the right spark plug wire harness, position it aside, and remove the drive belt tensioner. Then, please disconnect the vacuum brake booster hose from the vacuum connections, position it aside, disconnect the MAP sensor connector and hose, and remove the right valve rocker arm cover. Finally, you should clean the sealing surface on the cylinder head, clean the valve rocker arm cover bolts of all thread locking adhesive, and clean and inspect the valve rocker arm cover.
