It is possible that there is an air intake/breather hose adrift from when the clutch was replaced.Lots of parts have to be removed to do a clutch on these.The other possibility is a split/collapsed engine to inlet breather hose,but this is an absolute pig to change as it requires removal of the inlet manifold.This would not be disturbed for clutch renewal.hth

thanks , but have checked hoses, all appear ok, have now been told that it has a timing chain rattle, and i might as well scrap it as the cost of removing the engine to replace the timing chain , is just not worth it ?.nobody really seems to know what the vacume noise is ,or whats causing it ?. i am not sure what to do now , as i need the car , but cant afford the cost of replacing timing chain , or replacing the engine for another one , have been quoted £370 for a engine from spares yard , but they only supply , not fit .. any help would be very usefull , .thanks..
