Common problem with all lycomings due to splash fed lobes and lifters. There is
a relatively new option which involves drilling small holes into the heel of
the lobes, one feed hole into the centre cam bearing journal and plugging the
ends of the camshaft ( they are hollow ) . Some engineers will offer this as an
extra. In my opinion well worth doing, in fact have just done my own cam for an
IO-360 I am building (experimental).

A LAME friend of mine when he was in Melb would send his IO-540 engines to
Brisbane Aero Engines for overhaul - they . would charge more for overhaul but
would do extra which he would want for extra reliability. In an overhaul "you
get what you pay for".
