Somewhere earlier I saw a comment that Jake had recommended using 911 Valve Adjusters in the Type-4 engine... Or maybe he had recommended against it. I can't remember.
Anybody out there have experience in this? My adjusters and adjuster nuts were pretty gnarled when I got my car a few years ago. Now with bi-monthly adjustments, I'm looking to replace them. Will the 911 adjusters fit the existing rocker arms? Do I need the same nuts? If I go ahead with this, should my properly adjusted valves run quieter? And is there any advantage to replacing the springs? As a result of some moderate leaky valve guides, my plans are to have the heads re-built this winter. Should I wait until the heads are rebuilt, or is there any reason I shouldn't go ahead with the adjusters, nuts and springs right now? Any thoughts? My thanks. Eric Read |

you'll need a set of 1.7 rockers and then you must shave .040 off the underside where the swivel would contact when drawn up tight.
I.M.O. was a great improvement, kinda' removes some of the "thrashing machine" v.w. sound. mike |
