Nissan 13207-ET000 Seal-Oil,Valve

First, twist out the cylinder head and lay a flat clean surface on a very strong table. Utilize a large clamp type spring anchor that also uses a valve spring compressor adapter to compress valve springs for Toyota Sequoia gathered at the recommended locations to compress each valve spring, with the bottom part of the tool in contact with the valve to be removed. Wind the spring just a little bit to release the keepers if the battery is not working, you can use a magnet or a small pair of pliers. Working from the top, use a piece of'wire to remove the valve spring with its retainer next, extract the old valve stem oil seal with the aid of the pliers. Examine the valve and its stem for signs of breakage; turn the valve in the guide which needs to produce audible or visible signs of lateral movement that implies bending. Slightly withdraw the valve from the guide and slide it up and down to see if it will bind; If it does,the valve is likely to be bent or the guide worn requiring replacement of the cylinder head. Before fitting the valve stem, apply a thin coat of engine oil on the valve stem and Place the valve stem in the cylinder head, where the new seal is to be fitted, we shall use the plastic seal protector to avoid tearing the new seal. If a seal protector is not accessible, provide a layer of cellulose tape around the valve stem. Apply multi-purpose grease on the new seal and fitting it over the valve stem, using bare hands and the protector or tape should be removed when the new seal touches the guide. Install a deep socket of the correct size and slightly banged the new seal down at the top of the valve guide. Put the spring over the valve with the retainer located, push the valve spring and retainer aside, and install the keepers into the groove, if possible, grease keepers for better installation. Pull the trigger of the spring tool to open it and make sure the keepers are well locked in place. Replace the lifters bring back the camshafts, and carry this process in the reverse manner to the one followed while removal. Crank the motor and look for oil leaks, and strange noises coming from the valve cover gasket.

Lubricate the new seal with multi-purpose grease and push it down over the valve stem by hand, then remove the protector or tape once it is seated against the guide.
