Disassembly |
Identify MLA, valves and 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.
|
3. |
Remove the LH/RH intake camshaft OCV (A). |
Inspection |
1. |
Inspect for flatness.
Using a precision straight edge and feeler gauge, measure the warpage of the surface contacting with the cylinder block
|
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 valves.
|
3. |
Inspect valve seats
Check the valve seat for evidence of overheating and improper contact with the valve face.
If the valve seat is worn, replace cylinder head.
Before reconditioning the seat, check the valve guide for
wear. If the valve guide is worn, replace cylinder head. Recondition the
valve seat with a valve seat grinder or cutter. The valve seat contact
width should be within specifications and centered on the valve face. |
4. |
Inspect valve springs.
|
1. |
Inspect MLAs.
Using a micrometer, measure the MLA outer diameter.
|
2. |
Using a caliper gauge, measure MLA tappet bore inner diameter of cylinder head.
|
3. |
Subtract MLA outer diameter measurement from tappet bore inner diameter measurement.
|
Reassembly |
Thoroughly clean all parts to be assembled.
Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
Replace oil seals with new ones. |
1. |
Install the valves.
|
2. |
Install the MLAs.
Check that the MLA rotates smoothly by hand.
|
3. |
Install the LH/RH intake camshaft CVVT OCV (A).
|
Installation |
|
1. |
Install the cylinder RH head.
|
2. |
Install the RH cylinder head bolts.
|
3. |
Install the rest of the parts in the reverse order of removal.
|
1. |
Install the cylinder LH head.
|
2. |
Install the LH cylinder head bolts.
|
3. |
Install the rest of the parts in the reverse order of removal.
