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 |

I here the CB ones are ok. It's the empi and bugpack stuff you need to stay away from. Don't know first hand though.

The rest are cr*p, more or less. You care about your work? Use the Porsche ones. You just wanna brag (I can use that word, right? I mean he doesn't have a patent on it or anything, does he?) you have "swivel feet" and don't give a rat's arse about the quality of the work? Use the CB ones. Personally, for a stocker, I don't see any reason to use anything than good quality stock adjuster screws and nuts. Mind you, there are some el cheapo screws out there that aren't worth the price of the postage to get 'em to you. The Cap'n |

Look at the thickness of the metal where the porsche ones are clearanced for the swivel of the foot, that's where they break on a missed shift. Real experience with racing motors says the CB ones beat the Porsche ones. ALL of my 914s have them. Unless you'd like to argue that an oil pressure fed adjuster with a larger bearing surface on a thicker shaft is going to be weaker? |
