1)Disconnect negative (–) cable at battery.
2)Remove air cleaner assembly and air cleaner outlet hose. 
3)Remove high pressure fuel pump cover.
4)Remove ignition coil assemblies.
5)Disconnect engine harness clamps (1), if necessary.
6)Remove engine harness bracket bolts (2).
7)Remove oil level gauge (3).
8)Disconnect breather hose (4) from cylinder head cover.
9)Loosen cylinder head cover bolts No.1 (1) and No.2 (2) in numerical order (“1” – “14”) evenly and gradually.
10)Remove cylinder head cover with cylinder head cover gasket.
Installation
1)Remove oil, old sealant and dust from sealing surfaces on cylinder head and cover.
2)Install new gasket (2) to cylinder head cover (1).
4)Install cylinder head cover to cylinder head.
NOTE:
When installing cylinder head cover, use care so that cylinder head cover gasket will not get out of place or fall off.
5)Tighten cylinder head cover bolts No.1 and No.2 according to the following procedure.
a)Temporarily tighten cylinder head cover bolts No.1 (1) to position the cylinder head cover.
b)Tighten cylinder head cover bolts No.1 and No.2 to 5.0 N·m (0.51 kgf-m, 4.0 lbf-ft) in numerical order (“1” – “14”) evenly and gradually.
c)Retighten cylinder head cover bolts No.2 to 10 N·m (1.0 kgf-m, 7.5 lbf-ft) and cylinder head cover bolts No.1 to 7.5 N·m (0.76 kgf-m, 5.5 lbf-ft) in the same manner as in Step b).
Cylinder head cover bolt No.2* (b): 5.0 N·m → 10 N·m (0.51 kgf-m → 1.0 kgf-m, 4.0 lbf-ft → 7.5 lbf-ft)
