• | SA9124E Valve Spring Compressor/Remover

1. Remove intake and exhaust manifolds:

1.1. | Remove spark plugs.

1.2. | Remove the nine intake and eight exhaust manifold mounting nuts.

1.3. | If cylinder head intake and exhaust manifold studs come out, nuts should be removed from studs, threads cleaned, and studs carefully installed.

2. Uniformly remove rocker arm assembly attachment bolts, the 2 rocker arm shafts, and rocker arm assemblies guide plates and lifters.
3. Remove the rear cylinder head plug or camshaft thrust plate and screws.

Important: An impact driver and T-40 TORX™ are required to break the screws loose if the camshaft is removed out the front of the cylinder head. New TORX™ screws are usually required if the camshaft is removed out the front of the cylinder head.

Important: The camshaft can be removed out either end of the cylinder head. The camshaft plug must be driven inward or toward the camshaft and removed with a magnet from the cylinder head. A new plug is required when the camshafts is removed out the rear of the cylinder head.
