Racers. Do you worry about oiling issues, or do you just drive?

The down side on this style is you need to remember to fill it EVERYTIME you turn the motor off and do it the same way each time so you can get consistent oil level readings.

So if I were to bypass the pressure switch that activates the EPC solenoid valve and just have a switch to turn it ON/OFF, would that work as well as the Electric Valve? I could easily test that just by some minor rewiring work, without physically removing the pressure switch. I like the EPC valve because it is a one-way valve and fills up the tank when turned off. I'm currently setting up my Race Capture and AnalogX system and hope to have oil pressure data at 2 locations: the standard bank 1 valve cover location, and also at the inlet of the remote oil filter (before the filter/cooler, after the oil pump). That is just across from where the Accusump feeds into the circuit (at the outlet of the remote oil filter). This should give me info on oil pump outlet pressure, and total pressure drop across the filter, cooler and engine bearings.
