Engine rattle, heat shields? Water pump? IMS?

[marks44]

Hi guys, 200 986 2.7 tiptronic.
.Finnally got the Boxster on the road after an enforced year stood.It sounded a bit rattly when I started it up.I thought it was the tapetts but it has persisted. I have done about 50 miles in it since all short journeys, and it still making the same noise.Not knowing much about these engines not sure if it's something more serious than a loose heat shield, water pump, alternator bearing???Its a rattling noise doesn't seem to have affected the performance, speed, acceleration, engine temperature. I have also noticed a slight smell of petrol in the car, but it again just lingers and goes. If I could upload a video you could hear it but the site only allows images.Hopefully see what you think.Im not driving it and am contemplating recovered to an Indy for assessment, so any suggestions will be gratefully received. Hopefully other 986 members club members will chime in.
