Igor: Thanks for input. Maybe I made a mistake. Suspect matter in expansion tank is 
dark brown.. consistency is greasy or jelly like... feels like grease at contact, smells 
like antifreeze.... I drained the whole system and examined coolant.. it looks normal 
and no oil apparently in suspension..... Appears like some type of emulsion effect on 
the tank's surface.
Checked all your suggestions..all looks and reads normal. 
Coolant was regular Prestone (green) combined with "Red line" water wetter.. Perhaps the 
two did not get along too well....
Sorry about panic reaction will keep you posted.. my soul has partially returned to my 
body...
