Heeeelp! My daughter has a 2003 Astra 1.6SXi 16v. The cam belt pulley failed causing the belt to slip, bending all the inlet valves. The head was repaired, new valves, head set, cam belt, pulleys etc . The car now burns oil at an alarming rate, and smokes like mad, particularly after starting up. It did not have this problem before the cambelt incident. Anyone got any ideas lease, as she has spent too much to scrap the thing.
