Hi everyone, im knew to this site so please be nice lol. I brought a focus ST 2007 plate from a dealer last Wednesday, i did about 120 miles before the engine management light came on. So i stopped driving and looked under the bonnet, and there was oil over the engine and it's lost half of its coolant. (just had a service) so im not happy! I rang dealer and got the car sent over to them, they have got back to me saying it was a seal on the oil filter housing? Could this course the engine management light to come on dash, and lose half its coolant?? Please help!!! Thanks joe
