Removal and Installation REMOVAL Remove the timing chains. Remove camshaft position brackets (RH shown, LH similar). Remove the camshaft brackets and the camshafts. Mark the camshafts, camshaft brackets, and bolts so they are placed in the same position and direction for installation.
Removal and Installation of Valve Oil Seal REMOVAL Turn crankshaft until the cylinder requiring new oil seals is at TDC. This will prevent valve from dropping into cylinder. CAUTION: When rotating crankshaft, be careful to avoid scarring the front cover with the timing chain. Remove camshaft relating to valve oil seal to be removed. Refer to EM-76, "Removal and Installation". Remove valve lifters. Refer to EM-76, "Removal and Installation". Remove valve collet, valve spring retainer and valve spring using Tool. CAUTION: When working, take care not to damage valve lifter holes.
