Re: Running without Balance Belt
Well, just come back from Autolusso with a new balance belt fitted - engine was quiet as a mouse.
The vibration at 1800 and 3600rpm that came in after the cambelt change two years back has completely disappeared, and the engine is overall quieter at all speeds. So for my JTS at least, the balance belt seems to be pretty effective at smoothing everything out as the engine does its whizzy stuff!
No long-term damage is visible, thank goodness, but if anyone else suffers from abnormal noise after getting a cambelt done at an Alfa/Lancia indie in Catford it might be worthwhile checking whether they have put back all the bits they claim to have done.
