My most efficient way of doing it was to .... get someone else to locate the pushrods !! I used to hang around with a mate who had extremly long and moveable fingers , it was unbelievable to watch ,we'd struggle for 10mins to half an hour He'd come along laugh call us puny humans and sort it it two ticks ,when ever I have to do this job I think of Kenny Sach and wish he was around, always ended up dry as well which was an additional bonus, regards BobH.
