CYLINDER HEAD COVER
REMOVAL
1. Disconnect battery ground cable.
2. Remove clip, remove air cleaner cover and air duct.
3. Remove intercooler assembly.
Refer to “Intercooler” in this manual.
4. Remove PCV hose.
5. Remove bolts which fix noise insulator cover then
remove noise insulator cover and insulator.
6. Remove high pressure oil pipe at cylinder head
side.
Take care when removing the injector oil pipe,
because sometimes, during removal, your hand
can be injured by the remaining high pressure oil.
INSTALLATION
1. Cylinder head cover.
1) Install the cylinder head cover gasket to cylinder
head cover.
2) The gasket must be set perfectly with no loose
areas.
3) Apply liquid gasket (TB1207B or equivalent) to
the rubber seal of the camshaft end, injector
harness gasket area and No. 1 camshaft
bracket.4) Tighten cylinder head cover fixing bolts to the
specified torque.
Torque : 9 Nꞏm (0.9 kgꞏm/6.5 lb ft)
2. Fill with about 300 cc of engine oil from the high
pressure oil pipe installation port of the oil rail using
an oil rail filler. If assembled without filling the oil rail
with oil, the time for starting the engine will be
longer.
3. Install the high pressure oil pipe immediately and
tighten the sleeve nut to the specified torque.
Torque : 80 Nꞏm (8.1 kgꞏm/57.9 lb ft)
