Overnight my S-max has turned in to a futuristic hover skateboard/ufo! It is making a high pitched whistling noise like a kettle (not a fan belt screech). Checked the coolant system and all seems ok. Temperature gauge is ok too.
Took the oil dipstick out and a lot of air rushed in to the vacuum and the whistling stopped. Put dipstick back in and it was sucked out of my hand back in to place by the engine drawing in massive amount of air. As soon as dipstick was in place the engine started whistling again trying to suck in air from somewhere else. Same for the oil filler cap. With it removed if I put my hand over it my palm was sucked tightly on to make a seal- i.e. the opposite of an engine breather problem where air is being expelled.
Any ideas gratefully received.
Its a petrol 2.5T engine 56 reg.
