can anyone help with some info I started car one day and drove out driveway then car cut out and wouldn't start again and it sounded like the timing belt had snapped but belt had been done and in checking belt hadn't broke and timing marks were bang on  so tried starting it the following day still sounding like no compression but slowly I though the battery was going flat but then the car started and I don't have a clue what happened. does this engine have a valve or something that can make the car sound like no compression
