[Vwdiesel] Is it weird oil pressure?

[Libbybapa at wmconnect.com]

The pump is fine, large gears, almost no wear, with nothing plugging it.
Does anyone have a TD with an oil pressure gauge reading off the head port?  
Does the pressure behave as previously described?
I really need the definitive yea or nay on whether or not that behavior is 
normal.  I would hate to ventilate the block due to not addressing an issue, but 
are reluctant to tear into the motor without just cause.
