[s-cars] [;s-cars] What's leaking?

[Thomas R Green]

Tony,

These "what's leaking?" posts are generally unproductive because no  
one can see the leak
by email.  : - )  Also, I am not sure what you mean by the pressure  
regulator valve that would
be seen when looking around for the t-piece.  Are you referring to the  
expansion valve or
orifice tube for the a/c that is in the plenum area, and thus, the  
hoses are a/c hoses?  Then,
one might assume the oily substance came out of the hose connections  
and is PAG oil.
