Hello. I with the problem of leaking engine oil in the Opel Corsa b 1.0 from the sensor, I'm not mistaken, the temperature. Namely, in the engine on the top left there is a sensor, I guess it is from the temperature, I get oil from it, when I start the car it leaks under pressure until it wraps the radiator and stripes. I saw when I pulled out the sensor that there is a rubber gasket in it but that it does not meet the seal, from under the copper washer it does not leak just with this sensor. What is the reason and how to fix it?
