2. Remove camshaft position sensor brackets (RH shown LH simi-
lar).
3. Remove the intake and exhaust camshaft brackets and the cam- shafts.
• Mark the camshafts, camshaft brackets, and bolts so they are
placed in the same position and direction for installation.
• Equally loosen the camshaft bracket bolts in several steps in the numerical order as shown.
4. Remove valve lifters, if necessary. NOTE:
Identify installation positions to ensure proper installation.
5. Remove secondary timing chain tensioner from cylinder head • Remove secondary tensioner with its stopper pin attached.
NOTE:

1. Before installation, remove any old Silicone RTV Sealant from
component mating surfaces using a scraper.
• Remove the old Silicone RTV Sealant from the bolt holes and
threads.
• Do not scratch or damage the mating surfaces.
2. Before installing the front cam bracket, remove the old Silicone RTV Sealant from the mating surface using a scraper.
• Do not scratch or damage the mating surface.
3. Turn the crankshaft until No. 1 piston is set at TDC on the com- pression stroke.
• The crankshaft key should line up with the right bank cylinder
center line as shown.
4. Install camshaft chain tensioners on both sides of cylinder head. Refer to EM-182, "Removal and Installation"
.

Inspection after InstallationINFOID:0000000009460570
INSPECTION OF CAMSHAFT SPROCKET (INT) OIL GROOVE
WARNING:
• Check when engine is cold so as to pr event burns from any splashing engine oil.
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT and
it is directed according to inspection procedure of EC section. Refer to EC-716, "Diagnosis Proce-
dure".
1. Check engine oil level. Refer to MA-26, "ENGINE OIL : Inspection"
.
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to FL-5, "Inspection"
.
b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove intake valve timing control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve cover oil hole.
End cranking after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engi ne oil from splashing on
worker, engine components and vehicle.
• Do not allow engine oil to get on rubber components such
as drive belts or engine mount insulators. I mmediately wipe off any splashed engine oil.
5. Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from intake valve timing control solenoid valve cover oil hole.
6. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary.
7. After inspection, installation of the remaining components is in the reverse order of removal.
