elle, you keep saying that, but i seriously doubt it to be true. the
seals that typically leak are the upper ones. they are the ones that
get disturbed every time the rocker cover comes off and they are the
ones that have to bridge the least well defined gap. replacement of
those upper seals cures 99.99% of leakage 99.99% of the time. the lower
seals are good to replace if you need to do head or cam work, but other
than that, leave well alone. inspect the spark plug tubes some time -
the leakage path is /always/ [99.99%] from the upper seal.
