Removal |
|
Mark all wiring and hoses to avoid misconnection. |
In case of removing the high pressure fuel pump, high
pressure fuel pipe, delivery pipe, and injector, there may be injury
caused by leakage of the high pressure fuel. So don’t do any repair
work right after engine stops. |

Remove the exhaust CMPS (Camshaft position sensor) (A) after removing the engine hanger (B). |
26. |
Remove the injector & rail module (A). (Refer to FL group) |
27. |
Remove the cylinder head.
|
Disassembly |
Identify MLA(Mechanical Lash Adjuster), valves, valve springs
as they are removed so that each item can be reinstalled in its
original position. |
1. |
Remove the MLAs (A). |
2. |
Remove the valves.
|
Inspection |
1. |
Inspect for flatness.
Using a precision straight edge and feeler gauge, measure the
surface the contacting the cylinder block and the manifolds for
warpage.
|
2. |
Inspect for cracks.
Check the combustion chamber, intake ports, exhaust ports and
cylinder block surface for cracks. If cracked, replace the cylinder
head. |
1. |
Inspect valve stems and valve guides.
|
2. |
Inspect the valves.
|
3. |
Inspect the valve seats
|
4. |
Inspect the valve springs.
|
1. |
Inspect the MLA.
Using a micrometer, measure the MLA outside diameter.
|
2. |
Using a caliper gauge, measure MLA tappet bore inner diameter of cylinder head.
|
3. |
Subtract MLA outside diameter measurement from tappet bore inside diameter measurement.
|
1. |
Inspect the cam lobes.
Using a micrometer, measure the cam lobe height.
If the cam lobe height is less than standard, replace the camshaft. |
2. |
Inspect the camshaft journal clearance.
|
3. |
Inspect the camshaft end play.
|
1. |
Check the cylinder head bore mark.

Exhaust Camshaft Bearing Specifications
|
1. |
Inspect the CVVT for smooth rotation.
|
Reassembly |

Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
Replace oil seals with new ones. |
1. |
Install valves.
|
2. |
Install the MLAs after appling engine oil.
Check that the MLA rotates smoothly by hand.
|
