I'm sure I can come up with an oil pressure check. I have a few old
gauged here I'm sure I can rig up. Where do I need to be PSI wise ?
So are you saying the oil filter has an O-ring other then the one on
the outside of the block ( from filter to where you screw it on block
externally ) - meaning it's accessable with the pan off only ?
As far as taking off pan ( estimated time of on / off work, and will
I need a pan gasket only ? )- should I buy the O-rings in advance
and do them regardless.
So chances are, oil could be sucking up the tube but bleeding back
into the pan from the O-ring between tube, and block ?

Is there anything else I can check ?
I think in the meantime I'll do the timing belt, buy the parts for
the pan. I appreciate the help.
One last thing - I normally don't do anything other then the belt on
timing belt setups normally, does volvo require you do anything else
like the tensioner ?
