About to embark on thesame project, bought the kit from Caterham but not guidance notes sent . Managed to talk to a very helpful R&D engineering student who managed to raid the archives and set me all the building notes which includes a memo from Mike Dixon dated1989 which emphasises the need to drill a 1/16th hole in the block to an oil gallery to lubricate the screw gear!
Have snt hem diret to you by e-mail.
