Got a Corsa B sxi 1.2 16v.
Have noticed that the engine rattles, as thought the timing was out, when I change gear (as in 2nd to 3rd, when you lift the clutch in 3rd it rattles as the revs pick up) this also happens when on the motorway when trying to sit at 80mph except this time its a constant rattling. if you acceletare / slow down it goes away.
I belive this has a timing chain rather than a timing belt.
I dunno.....please help
