| 1. The need for more hardware, 6-vane pump, just indicates a bigger problem.   
I am assuming you are using the car for a fairly normal style of driving.  You 
can try just pulling the stat to eliminate it as a problem.  But, my opinion is 
that you have some significant blockage in the block, assumed your current pump 
is good.  Have done any flushing and back -flushing?  
2. The valve is supposed to keep the pads/shoes close but not drag as to be 
restrictive.   On a previous car I bypassed it as I thought it was causing a 
problem at one wheel only to learn the real problem was a crushed brake line at 
that wheel.   Didnâ??t notice any difference running without it.

Hello list.  Two questions for the collective expertise.  1961 TR3A.
1.  What are the disadvantages of NOT putting a thermostat in the engine in
Florida?  I found out that the prev owner did not put one in.  So I
installed a new bellows type and it raises my normal operating temp from
just under 185 at idle to about 200+.  I verified it is working in pot of
hot water.  Opens at 180.  I have a stock water pump, new aluminum radiator
and yellow plastic fan on backwards as standard upgrade. Thinking that it is
restricting water flow.   I am considering pulling thermostat and running
without one and installing 6 blade water pump upgrade that I just got from
Moss.  Could also be the temp gauge but haven't verified.  
2. on my hydraulic brake lines, I have a restrictor valve assembly (part
number 116197 - pg 54 of parts manual), like my early TR4. Installed just
before 5 way connector on passenger side frame near front tire.  My brakes
drag a little and it isn't the rear drum adjust.  I had heard that the valve
assembly can cause that outcome when faulty.  I also heard it is ok to
remove it and just attach the brake line to the 5 way connector.  Any
thoughts on doing this?
Thanks,
