Engine Coolant Sensor problem reveals oil in intercooler
For the 1st time since owning it for two years, my 2000 plate 1.8TQ is giving me occasional starting problems. I looked at the forum and it's been suggested that the engine coolant sensor is changed. I've not noticed a problem with the gauge at the dashboard.
Anyway, I went to Euro Car Parts and they had two different types. So I left it and went to look at the sensor last night, which on my car is on the radiator inlet pipe at the bottom of the radiator. Needless to say as it was getting darker I couldn't get the cable off the sensor. Should it come off when pulling it, or is there a clip underneath to release it?
To make access easier I took the intercooler to throttle body air hose off, at the intercooler outlet and found some oil there, enough to run into the hose when I pulled it up for a better look.
I would expect some condensation as the compressed air is cooled but didn't expect oil. Do I have a problem with the turbo?
Any experts out there that can advise?
