Dear Abby,

I've never written to you before, but I need your advice on a crucial decision.

I've suspected my wife has been cheating on me. There are the usual signs -
mysterious phone rings, unexplained absences, coming home late, and being
dropped off, not in front of the house, but around the corner.

I have never broached the subject with my wife.

Last night she went out. I decided to really check on her.

I parked my Harley-Davidson next to the garage, then hid behind it to get a
good view of the street around the corner when she came home.

Crouched behind my bike, I noticed oil seeping through the gasket between
the rear head and rocker-arm cover.

So ... is this something I can easily repair myself or do you think I should take
it back to the dealer?
