i got crank angle sensor for £15 just b4xmas ,ive got a 98 8 valve and was doing same as yours , i fitted my self but if your a bit warey just follow your haynes manual on removing front engine mount , it will get the starter motor out the way for you , you neednt remove the mount , once you got motor and its brackets out the way , remove oil filter and follow your wire off sensor down to engine block to were crank sensor is theres a philips screw just to the right of it remove and out she comes , you neednt get under the car . hope this helps
