Oil temp sensor questions RB25/30 Hi All, Hoping someone knows a bit more about this than me. We are about to fit an oil temp gauge to our track car - now with a 25/30 motor. We have used the RB30 oil pressure gauge sensor hole in the block (1/8 BSP just behind the oil filter) to run a braided line to the VCT feed in the head (via an elbow and some 1/8 & 1/4 BSP & AN fittings), and the easiest place to put the temp sensor is in this line. I am planning to replace a 1/4BSP joiner with a 1/4BSP T-piece (all female threads), and use a reducer to fit the sensor into the side of the T-piece. The T-piece will be at the block end of the line - as the oil exits the block, not as it enters the head. My question is - how much oil flows through this line feeding the VCT solenoid & into the head? This will determine how much the temperature in this line varies from the oil temp in the engine. I believe that this oil feed also lubes the front cam bushes, so I expect there is continous oil flow through the line - is this correct? Is the oil at this point likely to be the same temperature (or close enough for getting a reasonable indication) as the oil in the engine?
