Oldsmobile/Buick Repair: Dual Crank Sensor, crank sensor, air gap

Question
When installing a Dual crank sensor on a 1992 Olds 88 with a 3.8L engine what should the clearance be?

Answer
hi tom.clearence should be equal all around.so as to clear all of the fireing rings very important.if you get this wrong you will destroy the new sensor and prob the bal wheel.be sure to turn the eng bye hand if you come to any resistance stop and adjust.the air gap when right will be about 80.000 but clearence is the important factor.good luck please take a min of your time to rate my help ty billymac
