I am probably showing my ignorance here, but on which side of the oil filte=

Mike-
I am making my conclusion based upon the dreadful sound that came from the =
instrument console. My manual indicates that it will sound when oil pr=

So if you you are showing your ignorance by your post, I am confirming mine=
here! Given a 50/50 chance of being right (the pressure is either mea=
sured before of after the filter point), I would guess that the determinatio=
n (triggering the idiot light/banshee) is made after the filter and the filt=
er's resistance to flow could cause a pressure drop that is unsuitable, if t=
he filter impedes flow too much (?). Not sure. I only trust (but=
avoid) the banshee!
