R380 Oil Pressure Switch
Have read somewhere that you can use the existing housing for the temperature sensor fitted on V8 models to fit an oil pressure switch, which operates a light in case oil pressure becomes too low (catastrophic oil leak?) Sounds like something which is "too easy" not to try and do, anyone has done it and can point me towards the right type of sensor/switch required?
Thanks!

"Lubrication is by an oil pump located in the extension housing and driven by the layshaft with additional lubrication being provided by splash. The pump directs oil via a filter and internal drillings in the output shaft to lubricate the components. On non UK and non European models, provision for oil cooling is by means of a thermostat housed in a cover bolted to the side of the extension housing. The cover incorporates tappings for connections to an oil cooler. On UK and European models, the thermostat and cover are replaced by an oil by-pass block."
so it seems like you should be able to tap into the lines running to the oil cooler, or if you have a uk/euro truck, by getting the thermostat cover from a foreign truck and using the oil cooler port for a pressure switch. i don't know whether the thermostat would allow full pressure into the oil cooler lines unless the temperature was high enough.

Hmm, thanks for the replies, seems like it isnt as straight forward as i hoped for but probably doable. My gearbox does not have the oil cooler so i would need the manifold. My main concern is detecting severe oil leaks before it is too late. I know some people who destroyed their boxes in that way
