I have a Polo with a 1.4 16V BBY engine (http://www.ebay.com/sch/i.html?_nkw=engine) which I believe is common to the group. Posted on a VW forum but was unable to get a reply. If anyone here cares to respond that would be much appreciated. The top end was always a bit tappety tap, but is worse now. Slightly better when warmed up (but still worse than it was).
It's had regular oil (http://www.ebay.com/sch/i.html?_nkw=oil) changes that I've usually done myself, but last time I had someone else do it. I was wondering if they had changed the oil grade and that is partly an explanation. To be sure I did a flush using Comma, changed the filter, and the oil (http://www.ebay.com/sch/i.html?_nkw=oil) (Mobil 1 (http://www.ebay.com/sch/i.html?_nkw=mobil+1) 5W30).
The noise seems to be coming from the top of the engine (http://www.ebay.com/sch/i.html?_nkw=engine) so I'm guessing it might be the hydraulic tappets.
I've attached links to files with audio recordings of the noise (hopefully you can access them on Clyp.it):
1) Engine (http://www.ebay.com/sch/i.html?_nkw=engine) idling (almost cold) - bonnet closed (recording from drivers seat with window (http://www.ebay.com/sch/i.html?_nkw=window) down)

2) Revving between 1000-2500rpm bonnet closed (recording from drivers seat with window down)
1.4 BBY engine cold 1000-2500 rpm - Clyp (https://clyp.it/xfipknv0)
3) Engine (http://www.ebay.com/sch/i.html?_nkw=engine) idling (warmed up a bit) - bonnet open recorder held near top of airbox (http://www.ebay.com/sch/i.html?_nkw=airbox) cover
1.4 BBY Engine idling cold - Clyp (https://clyp.it/3rcuzadl)
Is this the hydraulic tappets?
