A 1P-3527 Valve Spring Compressor 1 Start By:
Remove the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head - Remove" for the correct procedure.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The removal procedure is identical the three cylinder and the four cylinder engines. The Illustrations show a four cylinder engine.
Clean the bottom face of the cylinder head. Check the depth of the valves below the face of the cylinder head before the valve springs are removed. Refer to Specifications, "Cylinder Head Valves" for the correct dimensions.
Place a temporary identification mark on the heads of the valves to identify the correct position.Note: Do not stamp the heads of the valves. Stamping or punching the heads of the valves could cause the valves to fracture.
Personal injury can result from being struck by parts propelled by a released spring force.Make sure to wear all necessary protective equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.
Ensure that the valve spring is compressed squarely or damage to the valve stem may occur.

Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The installation procedure is identical the three cylinder and the four cylinder engines. The Illustrations show a four cylinder engine.
Clean all components of the cylinder head assembly. Ensure that all ports, all coolant passages, and all lubrication passages in the cylinder head are free from debris. Follow Step 1a through Step 1e to inspect the components of the cylinder head assembly. Replace any components that are worn or damaged.
Inspect the cylinder head for wear and for damage. Refer to Systems Operation, Testing and Adjusting, "Cylinder Head Inspect" for the correct procedure.
Inspect the valve seats for wear and for damage. Refer to Specifications, "Cylinder Head Valves" for further information.
Inspect the valve guides for wear and for damage. Refer to Specifications, "Cylinder Head Valves" and Systems Operation, Testing and Adjusting, "Valve Guide - Inspect" for further information.
Inspect the valves for wear and for damage. Refer to Specifications, "Cylinder Head Valves" for the correct procedure.
Inspect the valve springs for the correct length. Refer to Specifications, "Cylinder Head Valves" for the correct procedure.

Use Tooling (B) to install new valve stem seals (4) onto each of the valve guides.Note: The outer face of the valve guides must be clean and dry before installing the valve stem seals.
Illustration 4 g03341246
Lubricate the stem of valve (5) with clean engine oil. Install valve (5) in the appropriate position in the cylinder head. Check the depth of the valve below the face of the cylinder head. Refer to Systems Operation, Testing and Adjusting, "Valve Depth - Inspect" for more information.
Install valve spring (3) to the cylinder head.
Position valve spring retainer (2) onto valve spring (3).
