Check this procedure... REMOVALand& INSTALLATION

6-300

1. Remove the grille, radiator, and timing cover.
   
2. Remove the distributor, fuel pump, oil pan and oil pump.
   
3. Align the timing marks. Unbolt the camshaft thrust plate, working through the holes in the camshaft gear.
   
4. Loosen the rocker arms, remove the pushrods, take off the side cover and remove the valve lifters with a magnet.
   
5. Remove the camshaft very carefully to prevent nicking the bearings.
   
6. Oil the camshaft bearing journals and use Lubriplate or something similar on the lobes. Install the camshaft, gear, and thrust plate, aligning the gear marks. Tighten down the thrust plate. Make sure that the camshaft end-play is not excessive.
   
7. The last item to be replaced is the distributor. The rotor should be at the firing position for no. 1 cylinder, with the timing gear marks aligned

1. Remove the intake manifold and valley pan, if so equipped.
   
2. Remove the rocker covers, and either remove the rocker arm shafts or loosen the rockers on their pivots and remove the pushrods. The pushrods must be reinstalled in their original positions.
   
3. Remove the valve lifters in sequence with a magnet. They must be replaced in their original positions.
   
4. Remove the timing chain/gear cover and timing chain (timing gear on V8 diesel) and sprockets.
   
5. In addition to the radiator and air conditioning condenser, if so equipped, it may be necessary to remove the front grille assembly and the hood lock assembly to gain the necessary clearance to slide the camshaft out of the front of the engine. On the V6-3.8L, remove the camshaft thrust button and spring. Remove the camshaft thrust plate attaching screws and carefully slide the camshaft out of its bearing bores. Use extra caution not to scratch the camshaft lobes.

1. Coat the camshaft with engine oil liberally before installing it. Slide the camshaft into the engine very carefully so as not to scratch the bearing bores with the camshaft lobes. Install the camshaft thrust plate and tighten the attaching screws to 9 - 12 ft. lbs. Measure the camshaft end-play. If the end-play is more than 0.009 inch; (0.228mm), replace the thrust plate. Assemble the remaining components in the reverse order of removal.
