How to remove and reinstall a valve cover on the Honda Ridgeline?

Disconnect the cable from the negative terminal of the battery. Remove the ignition coils. Remove the engine oil dipstick. Remove the upper intake manifold. On Honda 2WD models, disconnect the injector connectors, the rocker arm oil control solenoid connector, and the rocker arm engine oil pressure (EOP) switch connector. Detach the PCV hose from the valve cover. At the rear valve cover, remove the bolt retaining the power steering hose bracket and move the hose aside, if necessary. Remove the harness bracket bolts and disconnect the heated oxygen sensor connectors, the EGR valve connector, and the ECT sensor connectors. Remove the retaining bolts (Valve cover retaining bolls (rear valve cover)/ Valve cover retaining bolts (front valve cover)), then lift the valve cover off. If the cover is stuck to the head, bump the end with a block of wood and a hammer to jar it loose. Remove the original gasket and seal washers and clean the mating surfaces of the cylinder head and valve cover. If you removed the front valve cover, remove and inspect the PCV valve. Position a new gasket in the groove and install new sealing washers on the bolts. Install the cover and tighten the bolts, a little at a time. Follow the correct torque sequence. Reinstall the remaining components. Reconnect the battery. Run the engine and check for oil leaks.

Honda Ridgeline Valve Cover

Valve Cover of Honda Ridgeline cars includes rocker arm covers that have the responsibility to retain oil within the engine and to keeping off unwanted particles from penetrating into the same. Usually used from aluminium or plastic, these covers have fasteners that are interchangeable with gaskets to the crown of cylinder head or may contain other fixtures such as PCV valve, oil filter, etc. Eventually the gasket material used in valve cover can become very brittle and crack, develop leaks that can drip oil and cause further problems, while using plastic covers to can result in cracking and warping. It could be preferable to get metal, as it also provides an improved look for more clearance or if the engine has to be adjusted rather frequently. These are not for the street car as factory stamped steel covers are made to be permanently bolted to the engine while performance engine valve covers are made to be bolted and unbolted often possibly for a few times during a single season.
