Hi Lee H, On 1.6 TDCI the oil pressure switch should be front cylinder block adjecent to the bottom of dip stick tube. you may need to go under the car to change it.. Quote. Posted January 14, 2019. I was looking to purchase a 2012 focus 1.6 diesel with 25k miles on the clock. On examining the engine bay, I noticed some oil around the concertina intake between the air filter and the turbo. On removing the intake pipe, there was about 15ml of oil in the pipe. I assume that the oil came from the rocker cover breather. On the latest Duratorq 1.4 TDCI engine, you reach it from the top. To the right of the engine block is an air intake pipe that runs to the front of the fan. a single screw above the fan holds it I'm going to be installing an oil temperature sensor on my 1.6 tdci and I'm wondering if anyone has either A, done it before, B has an idea where is best to put it. Due to the filter used I cant use a sandwich plate unless anyone knows how to convert it to a cartridge filter and I don't want to place anything in line with the turbo So far have managed oil filter, pollen filter, air filter, wipers and bulbs.
