RE: SER1 Thermostat housing

Hi Ian and Jeremy,

On my '52 I machined off the thermostat pilot to compress the top 
thermostat gasket a few thou with the cover flange tight to the housing 
(no gap).  That takes care of the bending stresses on the cover ears, 
unequal fastener torque issues, and uneven gasket loading.  Can't imagine 
what Rover's engineers were thinking when they came up with the gapped 
design.

That was a year ago, and no leaks or problems from the thermo housing 
since.
