1991 Buick Park Avenue magnet missing

I WAS JUST LOOKING THAT UP FROM YESTERDAY. CODE 41 CAM SENSOR. WHAT YOU HAVE TO DO IS REPLACE YOUR TIMING CHAIN AND GEARS WITH THE MAGNET. **VERY VERY COMMON ON THIS ENGINE. WHEN YOU REMOVE THE TIMING COVER YOU WILL SEE THE ORIGINAL GEARS ARE MADE OUT OF PLASTIC AND THE NEW ONES ARE METAL. **BE WARE IF YOU DO DECIDE TO DO THIS I WOULD REMOVE THE OIL PAN AS WELL AND YOU WILL FING THE OIL PUMP PICK UP SCREEN FULL OF THE PLASTIC PIECES. ALSO ALTHOUGH THIS JOB IS TIME CONSUMING IS RELATIVELY AN EASY JOB AND INEXPENSIVE IF YOU DO IT YOURSELF. LET US KNOW HOW YOU ARE DOING.
