As the title, looks like my head gasket is on its way out. Out and about today shopping, the low level coolant sensor came on, was on the motorway so pulling over wasn't really an option, after 10 - 20 seconds it went off and didn't come back on, thought fine, maybe playing up. Got home, washed the car inside and out earlier, thought why'll im at it ill check the coolant and change some 8mm silicone id fitted for 7mm as it seemed to have been weeping. Checked the coolant and it was well low but it had a section in the corner that was quite brown. Changed the silicone coolant pipe and when i pulled it off, there was oil in the pipe, i say oil but i cant be a 100%, it definitely wasn't coolant, it was too oily in feel and dark. Checked the oil and it was fine all be it a little low. Thoughts gents!!!!
