AssemblyNBEM00201. Install valve component parts.
IAlways use new valve oil seal. Refer to ªVALVE OIL
SEALº, EM-35.
IBefore installing valve oil seal, install valve spring seat.
IInstall valve spring (uneven pitch type) with its narrow
pitch side toward cylinder head side (paint mark).
IAfter installing valve component parts, tap valve stem tip with
plastic hammer to assure a proper fit.

InstallationNBEM00211. Before installing rear timing chain case, remove old liquid gas-
ket from mating surface using a scraper.
IAlso remove old liquid gasket from mating surface of cylinder
block.
SEM161F
IRemove old liquid gasket from the bolt hole and thread.

Removal and InstallationNBEM0025CAUTION:
IWhen installing bearings, pistons, or other sliding parts,
lubricate contacting surfaces with new engine oil.
IPlace removed parts such as bearings and bearing caps
in their proper order and direction.
IWhen installing connecting rod nuts, and main bearing
cap bolts, apply new engine oil to threads and seating
surfaces.
IDo not allow any magnetic materials to contact the signal
plate teeth of drive plate.
