• Measure the diameter of the valve lifter.
Valve Lifter Hole Diameter
• Measure the diameter of the valve lifter hole of the cylinder head,
using suitable tool.
Calculation of Valve Lifter Clearance
(Valve lifter clearance) = (valve lifter hole diameter) – (valve lifter
diameter)
• If the measurement is not within specification, referring to each
specification of the valve lifter diameter and hole diameter, replace
either or both the valve lifter and cylinder head.
INSTALLATION
1.
Install the valve lifters if removed.
• Install removed parts in their original locations.
2.
Install the camshafts. Use the table below for identification of the
RH and LH, and intake and exhaust.
• Install so that the RH bank (B) dowel pins (A) and LH bank (C)
dowel pins (A) at the front of the camshaft face are in the
direction shown.

shaft hexagonal part if mounting space is small.
b.
Remove the stopper pin and release the plunger to apply ten-
sion to the timing chain.
c.
Install the chain tensioner cover onto the front cover.
• Apply liquid gasket as shown.

• Engine oil may squirt from IVT control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engine 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 insula-
tors. Immediately wipe off any splashed engine oil.
