Canton Oil Thermostat Install

If you disassemble all three of the units .... you will see how small the path ways are internally for the oil to go to the cooler and go thru the unit to get to the motor....

The passage ways on the Mocal and Earls have a relatively small section to transfer the oil in either direction and the thermostat is relatively small.....

The Canton unit is much larger in it's ability to move a larger volume of oil.....and the Thermostat is also much larger and will pass oil with out any restriction based on the size of the unit...... The pressure drop across the thermostat is about 2.5#lbs at 85#lbs of oil pressure

It's a Caltherm Thermostat used in the big Diesel's motors and not a small device......which is why it needs the larger housing that Canton uses..... so it can flow the large volume of oil

Morris,

Oil system plumbing ideas:

I have a 3 stage Peterson pump with two -12 scavenge ports and was intending on running "one -12 scavenge line" back to the oil tank, and the other -12 scavenge line via a Peterson Bypass valve to an oil cooler then to the Oil Tank, and the -10 bypass "relief valve" line to tank, that means fitting an extra two fittings to the tank as there is one -16 tank port. I also have a scavenge manifold with a -16 exit fitting and could run that through the -12 bypass valve to cooler and excess pressure would take the -10 bypass circuit to the oil tank, but I am not sure of the flow rate of that and that would mean blocking the oil cooler off manually!

Another idea is to use a Canton T/stat on one -12 scavenge circuit, then to the oil cooler, the other -12 circuit straight to tank, this thinking in my opinion is better than having a manifold down to one single -12 line to T/stat where all my scavenge oil has to pass, with two lines it will have an adequate flow rate.

We will be using an external tank heater before use so the oil will be heated, I am not a fan of cooling the oil pressure side, and really the only reason I am contemplating a T/stat or Bypass valve is to avoid blown oil coolers on start up, with cold thick oil in the pan hydraulicing its way through the cooler, but having said that the oil flow with the Canton uses the easiest path so on startup it will still send some oil through the cooler but shouldnt be an issue.

Quite a few racers run coolers on the scavenge without pressure relief and get away with it but I have seen F5000 race cars start up and blow coolers because of the scavenge oil pressure or pulse is worse even though the cooler is open ended.

All that sounds complicated for a street racer.........!
