RE: Digest Number 158

A question that has been nagging me about my YANMAR is, what is the

history of the 3GM30F developing “worm hole” or “pin hole” corrosion
in the cylinder walls ? Has “Nalcool 2000 / 3000” been effective as a
preventative ?

I have no knowledge of any abnormal wear conditions with regard to the
cylinder walls.
