Yes Dave I can elaborate a little.  Probably will have more to say later aft=
er I get my head out of ------ pressurization, avionics and other issues.

Major problem and why the engine was making aluminum is that the cam shaft a=
pparently should not have been used. It had been repaired with chrome on the=
 journals and besides being badly pitted some of the chrome must have been p=
eeling off and gouging the aluminum in the case where the camshaft rides.  T=
his item was sent out  to a repair shop and was red tagged as not restorable=
 due to the chrome treatment and both key ways being too beat up. =20

I am told that chrome treatment of these camshafts is not acceptable. =20

None of this information comes from my experience or knowledge base all has b=
een passed on to me.
