Question about 1997 Aston Martin DB7
Making a ticking sound from around the head.only when it gets hot.no loss of performance.tappit sound.also supercharger making a rattle sound.
Valve lifters can become partially clogged and this often makes them give you the tap tap tap sound, most audible at idle or low RPM. Short of replacing them all and the camshaft to boot, the only thing I've found that quiets them is using Engine Restore. Comes in a silver can, three sizes, 8 cyl, 6 cyl, & 4 cyl. Pretty much all the same just progressively bigger cans. Add it to your oil at the next change, and remember to use a flush first such as Gunk brand. Don't drive the vehicle with the flush in the oil, only idle it. I have no experience with superchargers so I can't offer any words of wisdom on that but imagine it's either rebuild or replace.

The internal combustion of the main valve is most likely either clogged or it has a loose spark plug that is constantly providing a spark without oil. Either that or your break pads have gone bad or just some seats and stuff loose, I'd have it checked on by your nearest professional.
