Chrysler 5047068AB Engine Intake Valve

Position the number 1 piston at TDC on the compression stroke. Remove the engine cover by pulling it up and off of the ballstuds. Disconnect the cable from the negative terminal of the battery. Blow out the recessed area around the spark plug openings with compressed air, if available, to remove any debris that might fall into the cylinders, then remove the spark plugs. Remove the valve cover. The lobes must be measured one set at a time. Rotate the camshaft(s) until two lobes on any one cylinder are pointing straight up and measure the clearances of those valves with feeler gauges. Record any measurements that don't fall within the specified range, as these will be used later to determine the required replacement lifters. Rotate the camshaft(s) until all the lobes have been checked. Remove the camshaft(s) for the valve(s) that you intend to adjust. Remove and measure each lifter with a micrometer, putting each lifter back into its bore in the cylinder head before moving on to the next lifter, and record the measurement for each lifter. To calculate the correct thickness of a replacement lifter that will put the valve clearance within the specified range, use the formula S - C = change, where S is the specified valve clearance and C is the measured valve clearance. Remove the lifter and read the size from the bottom of the lifter, then reduce the lifter by subtracting the specified valve clearance from the measured valve clearance or as close as possible to the calculated size. Install the camshaft(s) and check the valve clearances again to verify that they're now within the range. The remainder of installation is the reverse of removal.
