164 Engine Rattle

Hi... I wonder if anyone can help.
I have a 164 2litre 8valve and it has a rattle at idle which seems to be coming from the vicinity of the timing chain.
Can anyone give me an idea of what might be causing this and how serious it might be?
Thanks in advance... Ian

Re: 164 Engine Rattle

don't all the twin sparks do it just about?!

google "alfa 164 timing chain rattle" and there is a few results mentioning adjusting the tension, though never did it on the twin sparks i've owned.

Re: 164 Engine Rattle

Does it happen when cold? My TSpark had a rattle at idle which was apparently due to the tensioner not coming across until the engine warmed up or something. It wasn't noticeable and didn't happen once warm. The garage did an engine flush which helped, but it was never fully cured. It's done 50k miles like this and is still going strong.

The other rattle I had happened at 2500 revs exactly and was a bit of heatshield that had come loose. The garage ripped it off and it's been fine ever since.

Thanks guys for the replies.
I gather from what your saying that its nothing to worry too much about, ie its not likely to jump a tooth or break?
