Astravan 1.7 CDTi. I recently replaced the front mount for new as the rubber insert looked tired, and replaced and retorqued rear mount bolts. It felt better for a while, but a few days later began moving about again. I then just last week had the cambelt replaced, for which the side mount had to be taken off and refitted. Again, the van felt better for a day or two, but the engine began moving around loads after that. It's now worse than ever! Alternator belt squeals away when I'm reversing and sometimes when I just release the clutch. Sounds rubbish! Any advice? I just want the damn thing to stay still!
