WARNING:
Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
NOTE:
During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
NOTE:
Early build engines have 11 fastener valve covers, late build engines have 9 fastener valve covers. Do not attempt to install bolts in the 2 empty late build valve cover holes or damage to the valve cover will occur.
NOTE:
On early build engines, the timing chain rides on the inner side of the RH timing chain guide. Late build engines are equipped with a different design RH timing chain guide that requires the timing chain to ride on the outer side of the RH timing chain guide. For service, all replacement RH timing chain guides will be the late build design.

CLOCKSPRING
.
NOTE:
RH shown in illustration, LH similar.
NOTE:
Position a block of wood under the transaxle.
NOTE:
If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
NOTE:
LH shown in illustration, RH similar.
NOTE:
VCT
solenoid seal removal shown in illustration, spark plug tube seal removal similar.
NOTE:
Only use hand tools to remove the studs.
NOTE:
Only use a 3M™ Roloc® Bristle Disk (2-in white, part number 07528) to clean the engine front cover. Do not use metal scrapers, wire brushes or any other power abrasive disk to clean the engine front cover. These tools cause scratches and gouges that make leak paths.
NOTE:
Place clean, lint-free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages or the oil pan, may cause engine failure.
NOTE:
Do not use wire brushes, power abrasive discs or 3M™ Roloc® Bristle Disk (2-in white part number 07528) to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. They also cause contamination that will cause premature engine failure. Remove all traces of the gasket.
NOTE:
The Camshaft Holding Tool will hold the camshafts in the Top Dead Center (TDC) position.
NOTE:
The Camshaft Holding Tool will hold the camshafts in the TDC position.

NOTE:
When the Camshaft Holding Tool is removed, valve spring pressure will rotate the LH camshafts approximately 3 degrees to a neutral position.
NOTE:
The camshafts must remain in the neutral position during removal or engine damage may occur.
NOTE:
Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.
NOTE:
The VCT
bolt and the exhaust camshaft bolt must be discarded and new ones installed. However, the exhaust camshaft washer is reusable.
NOTE:
The camshafts must remain in the neutral position during removal or engine damage may occur.
