Regards Marvels' treatment ....... are you speaking of the Marvel's Mystery
Oil Top End Treatment or Marvels' Mystery Oil.(period!) They are two
different things. The cans they come in look almost identical but could
cause confusion. I have used the Marvels' Mystery Oil to loosen things when
all else failed, including WD-40, but never in an engine. I have never used
Marvels' Top End Treatment for anything so can't speak to its effectiveness.
The straight Marvel's Mystery Oil is really wonderful stuff for loosening
difficult nuts, bolts and fittings. I have seen it do the job when WD-40
wouldn't.  It is hard to find however, and in recent years  I could find it
only in one gallon cans if I can find it at all.  As I remember a gallon can
was quite expensive.

Subject: Re: Noisy Lifter - to replace or not?

Try about a quart of ATF or of Marvel Mystery Oil, or some Redline Lifter
Freer-upper in the crankcase (do not over-fill).  This worked for me (Marvel
Mystery) and has worked for many others.  I changed the oil after a couple
of hundred miles, but i still put about a pint of the mystery oil in with
the new oil to allow the cleaning to continue, which marvel reccomends.
