Hi had a look at 1.4 petrol car was pretty tidy however when running it noticed that on the front of the right hand side top of the engine was a sensor looks like it goes into the cam cover. The sensor was leaking fluid out when running seemed to be coming out of the centre of sensor where the wiring came out. Has anybody encountered this before I was wondering if the cam oil gallery was pressuring due to head gasket leak causing the sensor to fail and leak. Hadcanybody seen this before.
