The V8 Owners Forum -

OK here goes.... I've got a set of rockers which are from an SD1 Twin plenum that uses the group A push rods (ball one side and cup the other) now at the moment on the rockers, the adjusting screws are tack welded..... if I can remove the tack and rescue the threads then that's not a problem, but if I can't where can I get a replacement set from at a reasonable price as I want to sort out the preload on the lifters with the adjusters rather than aultering the pedastil hight on the rockers!

Cheers

Jono,

As I said as a reply in one of your many posts the Group A Rockers are Volvo B18/20



There are a few suppliers of these parts but it's still going to leave you with the problem of sourcing the custom made pushrods, as I also mentioned earlier the only source I know is John Eales JE Developments and he will want a small fortune for them..

What I suggested earlier is if you can determine the thread size of the adjustors is that you might just get lucky and find an adjustor from another engine that has a cup end that will match the standard rover pushrod.
