Have fully rebuilt a 1.2 spi engine and put it in my cinq sporting. Runs perfectly but when on idle there is a strange low pitch squeak kind of sound that seems to be coming from the cam belt side.
Everything is brand new, I have checked the tension on the belt and sprayed water on the belt whilst running to see if that made any difference and it did not.
I also disconnected the alternator just to prove that wasn't the culprit.
If I raise the revs even the tiniest amount the sound stops!?
Car drives and performs brilliantly, really happy with the upgrade, just a bit disappointed about this noise as it makes the car sound like a bit of a banger, especially after the amount of time and money I have put into it
Has anyone got any ideas as I'm out of them?
