hi all--and thanks again for advice on removing c-shaft bolt in july--i have just had another go at it--but this time with a home made tool--3 clouts with a lump hammer and it was off!! it took 20mins to make out of a old ring spanner, a 3in extencion bar (1/2in drive) and 18in of solid bar--1in dia--i would send a photo--but i am new to computers--but i have found a hole in the timeing case--just under the c shaft drive--its about 10-12mm in dia--does it need blocking up?--and wot should i block it with dear hazel-dear hazel--thanks --allen
