Cam/Crank Sensors

[Waterloo]

If you are going to be on that side of the motor, inspect the oil pressure sending unit, it is below the cam sensor on the block, near the fuel filter. Has the same look as the cam sensor, but is different in function. Check it for oil, they like to weep, and when they start that is a good time to replace.

Same with the Jake sensor, which is next to the cam sensor, in the side of the head, there is a wire clip that holds the Jake sensor in that needs to be pulled straight up to remove the sensor, check for oil weeping visually before touching it, no oil, leave it alone unless you are having Jake issues. If it is weeping it is a good time to replace the o ring in that if the sensor wiring looks OK. If the wiring under the cover looks old and brittle, best to replace that entire harness under the cover.
