Hi list,

While puttering around with the Temp Sensor II on my 87 Syncro, I noticed
that a  hose was disconnected from  thermostat housing (top).  It looks
like the hose is supposed to connect to the valve that is just below and
left of the Breather Valve on the housing.  My valve has been broken off
and a screw has been placed in the bottom end of the hose.

Can someone tell me what the purpose of this hose is?  Could the broken,
unsealed valve on the housing be causing me any performance related
problems?

Thanks in advance,

Jeff
