    Q:
    What lubrication should be applied to the valve stems, and how should you install the valves and valve springs during reassembly for the 1993 Chevrolet Beretta? Posted by Customer
    A:
    Apply moly-base grease or clean engine oil to the valve stem. To install the valves and valve springs during reassembly, position the valve springs (and shims, if used) over the valves. Compress the springs with a valve spring compressor and carefully install the keepers in the groove. Slowly release the compressor, ensuring the keepers seat properly. Apply a small dab of grease to each keeper if necessary. Repeat this procedure for the remaining valves.
