I had a visual inspection and iv sprayed water on belts and pulleys, they or it is making a very slight noise and completely disappears when water is sprayed but nothing out the ordinary, and ticking is still there, I first thought the ticking was best herd down by the bonnet open latch (grill area)that is were it seems loudest, but it could be the front top off engine it's hard to pinpoint, (I'd say it's like a bad tappet noise but not loud, can't hear it in cabin only at front off car, if previous oil was 10w40 or something like that. could it be because I have put 0w30 in.
