I got it done quite a while ago actually, the belts looked good, everything looked ok, managed to get the cambelt cover off partway, I always keep an eye on the oil level as it tends to burn an alarming amount of it, changed from 10/40 to 10/60 selenia racing, which is a thicker oil, especially after a friends gtv seized up!
So it looked ok but decided to get it seen to so I had new belts, tensioners, inc. rollers, and went for a new water pump and variator seeing as its all being done, cant remember the cost but after it sounded pretty sweet and mind was at rest. A good investment. I think the water pump and variator really wasnt that bad, but what if they had been?
So after that there was still a bit of rattle, especially from cold, then we worked out it was a missing bracket at the very front of the exhaust. it was mentioned before but looking underneath I thought it was the one behind.
The bracket had sheared off the cats, so a new/ 2nd hand one is expensive but we fixed it with welding a makeshift (quite simple) shape on.
There are other threads on this.
after this was done it was purring wonderfully.
it was worth getting that done as apart from the noise, a lot of weight was on the 2nd bracket down which had split.
Alfa released an upgraded reinforced bracket too so that is put on.
Thing is I'm abroad now so dont get to drive it!
