----------------------------
    After having 2 coolant leaks, rear heater and a oil cooler hose, I decided to monitor my coolant systems pressure. I  installed a couple of extra senders for  the electric  oil pressure gauge and  a switch so I can now monitor my oil, fuel or coolant pressure. The coolant pressure is 0 when cold and slowly rises along with the coolant temperature to around 10 psi, I assumed it would sit around 10 psi while the engine is hot.  Yesterday was the first time I have taken a long trip, about  3hrs since installing the sender. After climbing to 10 psi it started dropping off gradually  after 30 minutes  of driving to 2-4 psi and stayed there the rest of the  trip, it did the same thing on the way home.  I appeal to the wisdom of the list, do I have a problem?  I can find no coolant leaks, drips or drops. Temperature here has been in the 20- 40 degree F range.  Any ideas sought and appreciated.
