Installation
Reference: Camshaft, Tappet and Shim Inspection:M13A
1) Install tappets and shims to cylinder head.
Apply engine oil around tappet and then install it to cylinder head.
NOTE:
When installing shim, make sure to direct shim No. side toward tappet.
2) Install camshaft (1). Apply engine oil to sliding surface of each camshaft and camshaft journal then install them as shown in the figure.
NOTE:
Before installing camshafts, turn crankshaft until key position faces upward.
Refer to Timing Chain and Chain Tensioner Removal and Installation:M13A .
3) Install camshaft housing pins (1) as shown in the figure.
4) Check position of camshaft housings.
Embossed marks are provided on each camshaft housing, indicating position and direction for installation. Install housings as indicated by these marks.
A: I: Intake side or E: Exhaust side
B: Position from timing chain side
C: Pointing to timing chain side
5) After applying engine oil to housing bolts, tighten them temporarily first. Then tighten them by the numerical order in the figure. Tighten a little at a time and evenly among bolts and repeat tightening sequence two or three times before they are tightened to specified torque.

6) Install timing chain with crankshaft sprocket referring to Timing Chain and Chain Tensioner Removal and Installation:M13A .
7) Install timing chain cover referring to Timing Chain Cover Removal and Installation:M13A .
8) Check valve lashes referring to Valve Lash (Clearance) Inspection:M13A .
9) Install cylinder head cover and oil pan referring to Cylinder Head Cover Removal and Installation:M13A and Oil Pan and Oil Pump Strainer Removal and Installation:M13A .
10) Install radiator with cooling fan and connect A/T fluid hoses (vehicle with A/T), radiator inlet and outlet hoses referring to Water Pump Removal and Installation:M13A and Radiator Removal and Installation:M13A .
11) Adjust generator belt tension referring to Water Pump Belt Tension Inspection and Adjustment:M13A .
12) Adjust A/C compressor and/or P/S pump belt tension (if equipped) referring to Compressor Drive Belt Inspection and Adjustment (M13A Model) or P/S Pump Drive Belt Inspection and Adjustment .
13) Refill cooling system with coolant, engine with engine oil and A/T with specified A/T fluid (vehicle with A/T).
14) Verify that there is no coolant leakage, oil leakage and A/T fluid leakage (vehicle with A/T) at each connection.
With VVT
CAUTION:
• Keep working table, tools and hands clean while over hauling.
• Use special care to handle aluminium parts so as not to damage them.
• Do not expose removed parts to dust. Keep them always clean.
Removal
1) Remove cylinder head cover and oil pan referring to Cylinder Head Cover Removal and Installation:M13A and Oil Pan and Oil Pump Strainer Removal and Installation:M13A .
2) Remove timing chain cover referring to Timing Chain Cover Removal and Installation:M13A .
3) Remove timing chain referring to Timing Chain and Chain Tensioner Removal and Installation:M13A .
4) With hexagonal section (1) of intake camshaft (2) held stationary with spanner or the like, loosen mounting bolt of intake cam timing sprocket assembly (3) and remove it.
CAUTION:
• Never attempt to loosen intake camshaft sprocket bolt with intake cam timing sprocket assembly held stationary. Failure to follow this could result in damage to lock pin.
• Do not loosen bolt “a” because intake cam timing sprocket assembly is not serviceable.
5) Loosen camshaft housing bolts in such order as indicated in figure and remove them.
6) Remove camshaft housings.
7) Remove intake and exhaust camshafts.
8) Remove camshaft bearings (1) from cylinder head and camshaft No.1 housing.
9) Remove tappets (2) with shims (1).
Installation
1) Install tappets and shims to cylinder head.
Apply engine oil around tappet, and then install it to cylinder head.
NOTE:
When installing shim, make sure to direct shim No. side toward tappet.
2) Install camshaft bearings (1) to cylinder head and camshaft No.1 housing.
CAUTION:
Do not apply engine oil to camshaft bearing back.
Only a upper half bearing of intake camshaft bearing No.1 has some holes.
3) Install intake camshaft (1) and exhaust camshaft (2).
Align knock pin (3) and match mark (4) with notches (5) as shown in the figure.
NOTE:
Check that key on crankshaft timing sprocket is in match with notch on cylinder block referring to “Installation” of Timing Chain and Chain Tensioner Removal and Installation:M13A .
“a” Approx 30°
4) Apply engine oil to sliding surface of each camshaft and camshaft journal, then install them as shown in figure.
5) Install camshaft housing pins (1) as shown in figure.
6) Check position of camshaft housings.
