Have you tried tensioning the chain? You just slack the retaining nut on the front of the engine on the intake side. Let it idle for a few minutes and with the engine still on tighten the nut. This should cure your problem.

Loose chain

I have never heard of all these new procedures. Ya learn something new every day. I was just going by the Haynes Alfetta manual of yesteryear. They got the information from Alfa. I have been doing it like that for years without ever a problem. But I guess I will bow to the new way. Anyway, tighten your timing chain and adjust camshaft sprockets if necessary.
