Ed, Lynn and All,
The way I understood Lynn's reply was as follows........The oil
cooler has more flow capacity than the oil filter (at least a single
filter that most of us use).........The restriction caused by putting
the filter before the cooler has the potential of allowing the bypass
of the filter to open (pressure differential due to the lower flow
capacity of the filter) thereby allowing trash captured by the filter
to flow through the cooler and on to the engine........By locating
the filter after the cooler the chance of this occurring is much less
because of lower flow demands of the engine bearing system.......
Hope this makes sense.........Is that anywhere near to what you
were talking about Lynn ??
