There is oil leaking from where the cam pulse generator (at least that's what I think it is according to the service manual) bolts to the motor. Is this a big deal or should I simply tighten the bolt(s) and call it good?

 

there's an o-ring on it
it might need replacing, but i'd check to make sure the bolts are tight as you mentioned

 

Roger that.
Thanks.

 

Well there's only one bolt and it was definitely tight.
That must mean the o-ring is worn out. The cam pulse generator is one part, including the wiring pig-tail.
Can I just get a new o-ring or will I need to get the entire new part??
