All right, who put the damn double Re in the subject line anyway? ;)

Ric,

The older engines may have broken down more without the oil cooler,
but wouldn't that be due more to the oil breaking down because it
(the oil) wasn't being kept cool?  This seems much more likely than
a slightly cooler oil in a thin coat removing enough heat to cool
the engine compared to the amount of cooling air doing the job.
