Since going on maternity leave I have alot of free time, so I began rethinking my oil cooler setup. As mentioned in my thread the hardest part of the install is deciding how I am going to tap oil pressure and temp.
Now just quickly there is essentially a few different methods on tapping here for the two items above.
Now I had concluded that I was going to run two pressure gauge fittings off the sandwich plate, and then start my hoses. I am not sure if this is the best setup as I am not confident I'd get accurate readings of either oil temp/pressure. My thinking to this is the flow of oil when below 93C due to my Mocal sandwich plate with thermostat might not flow enough oil to log accurate oil temp?
So I began looking at alternatives. Almost everyone reccomends to tap the sump for oil temp. I really didn't like this option as to you would need to undo the threads on the defi sensor (possibly) and the adapter plug for every oil change. I dont want to be buying new sensor esepcailly every couple of years and whatnot, plus I have the fumoto drain valve as well...
So heres a thought, why not tap oil from the sump and still retain fumoto drain valve which would make oil changes much easier, and no requirements for undoing the fittings each oil change!
I ordered this as it was just $26 - Aeroflow metric extension M14 x 1.5 both male and female ends, and a 1/8NPT for sensor. Will be using a spacer here to convert for the 1/8PT defi sensor also.
So from the pan, aeroflow fitting, and then the Fumoto valve. the defi sensor would sit on top.
I do see two downsides to this though, hopefully my mitigants stand up against it though...
1 - weight. Adding the aerflow extension and defi sensor along with the fumoto valve puts extra stress and could lead to cracking of the sump... As the drain port on the S2000 pan is recessed in, you must use an adaptor to fit the futomo valve:
This piece is rather chunky, and I have had this adaptor and the fumoto valve for 9 months with no issues... The Aeroflow item is made of alloy so im confident that it is much lighter than this adapter, even combined with the defi sensor. so if i substitute the aeroflow item for the fumoto adapter, I should be fine!
2 - inbility to read oil temps. Traditionally you would get an adapter fitting to fill the sump plug, and on the end of the adapter is a small hole to screw in the oil temp sensor. This then means the actual sensor is protruded and kept in the bath of oil to read temps. For my proposed setup, the sensor will actually be outside of the oil pan, and instead of being inside the bath of oil, it is pointing facedown in the pipe for the sump plug. Now I am having thoughts that this might only read oil if I was to turn right, and oil swishes to the left and hits the sensor. Now I believe that even stationary, the defi sensor will still read oil. This is because I have drained oil before with the car flat, on all fours....
At the end of the day, I can test this before I finalise the oil cooler hoses, and this test would have only cost me $25 and a few hours... fingers crossed it all works, however I would like any positive/negative comments etc!
Now just quickly there is essentially a few different methods on tapping here for the two items above.
- Oil Pressure: double stacked sandwich plates, oem oil pressure location, inline gauge fitting where the oil cooler hose is.
- Oil Temp: double stacked sandwich plates, tap the sump or use the oem drain plug with an adapter fitting, inline gauge fitting where the oil cooler hose is.
