Not one generally to talk about this sort of thing on a public forum, but I really need some impartial advice on what could be a crucial decision. I’ve suspected for some time now that my wife may be cheating on me. If the phone rings and if I answer, the caller hangs up. My wife has been going out 'with the girls' a lot recently, although when I ask their names she always says, “Just some friends from work” I always stay awake to look out for her taxi, but she always walks down the road. Although I can hear a car driving off, as if she has got out of the car round the corner. Why? Maybe she wasn’t in a taxi? I once picked her phone up just to see what the time was and she screamed that I should never touch her phone again, why am I checking up on her etc. Anyway, I haven't raised it with her, as I think deep down I just don’t want to know the truth. But last night she went out again and I decided to check on her. I parked my motorbike next to the garage and then hide behind it so I could get a good view of the whole street when she came home. Crouching behind my bike, I noticed that the valve covers on my engine seemed to be leaking a little oil. So guys, please tell me. Is this something I can fix myself or should I take it back to the main dealer?
