I had an oil leak I could not trace recently, the drivers side of the engine bay was covered in oil even up the steering column, I then noticed my lack of brakes if they were used in like doing a 3 point turn, the pedal would go solid and I would not stop, normal braking was ok.
Turns out I had a dodgy brake vacuum pump and it was ****ing oil out the back of it and somehow spraying it everywhere.
