Hi all, my mate's dad is a mechanic, I'm not sure what model of Alfa it is but it has the Twin Spark engine in it. I've been told, when starting from warm the engine rattles and sounds like a diesel. He reckon's it could have something to do with the timing side of things. I've said to my mate that it sounds like the variator has gone. Could anyone confirm this?
Variators cause the noise you describe, which appears to be more prevalent on pre-2001 TS engines, according to that which I have read anyway. Ours is fine on an '01 registration, probably because I am a fanatical oil and filter changer,(nut case?)
