as i wrote in the last thread subject "product recall" i am fitting a timing belt to my omega 3.0 i've been looking in the haynes manual which says you need a lot of specialised equipment is this true? or can it be done with tools available for motor spares or general tools. also the earlier omega's have a timing belt interval of 40'000 where as the 97+ have an interval of 80'000 is this due to the new rollers? will i be able to tell if my police car has had the new rollers put in to increase the interval as i know that this is possible, as many garages advise the change over from the old type to the new type
