bolt placement for timing cover/water pump

If you don't go crazy with sealer there shouldn't be any to come loose and float around. Another plus to using sealer is it can help prevent the bolts rusting to the timing cover/block. I remember a guy here recently that snapped a water pump bolt off right at the head because it wasn't sealed and water seeped and froze it to the timing cover. He had a heck of a time prying it apart and the timing cover was roached by the time he got it apart.
