3.2 oil circuit.....
So I'm ready to install an external oil cooler up front for my 3.2.....it's a 914 conversion and when I open the MOCAL box I see that the moron sent me a -10AN thermostat...which NOT what wanted as my cooler and all the lines are NOT -10......
I am cutting into the oil line that connects to the engine direct the to oil tank Not the line that goes from the tank to the stock cooler...... so.....is this oil which is HOT, already gone thru the internal engine oil thermostat? Is it thin and safe to plumb in the cooler without another thermostat?

Mike,
On my 3.2 914, I have a AN 12 Mocal thermostat. The purpose of the external thermostat is to protect the external oil cooler and allow the engine to heat up faster. I have read where someone's external thermostat was not working and the high oil pressure kept breaking their external oil coolers. So I would recommend an external oil thermostat On my 3.2 914, the line that comes out of the bottom of the motor was cut just before the 90 degree bend that would point to the oil tank on a 914. The oil line then has a 90 degree an AN-12 fitting welded onto it that points to the passenger side of a 914. A SS AN-12 flex line runs to the front of the car behind the passenger rocker panel. Holes were drilled into the triangular supports that hold up the panel and then the lines went through the holes

Mike,
The Porsche factory external thermostat has a pressure relief too, so if it is cold and the oil viscous that you won't blow your cooler. "Ted" on this board connected his race car cooler direct to the scavenge system and popped the cooler one chilly morning (in San Diego, not Truckee  ).Mocal, for example, makes thermostats that don't have the pressure relief valves. However, if the thermostat is reliable, it won't open until the oil is warm enough to keep the cooler from blowing. Factory thermostat is highly recommended.
