Here's The Problem 356/912 Rocker Assemblies Experience

These parts are vulnerable to wearing through the original rather thinly hardened surface. Once that happens, the valves become harder and harder to adjust as substantial problems develop over time. A "step" develops where only the part of the rocker that contacts the valve stem wears. The surface that doesn't make contact isn't worn and so when you try and adjust the valve you have trouble because this "step" makes it difficult if not impossible to accurately adjust the valves. ... Those of us who have experienced this know exactly the problem and also know that except for a solution like our, there really is no solution.

AT RIGHT: Here we see the hard-faced surfaces we provide in this service. It's easily seen that a significant amount of material has been welded on and that the resulting surface has been machined, as appropriate.

The rockers we provide to you are like new, but have an even harder and thicker contact face. Your valve adjustment difficulties are now over. And this problem should never re-develop in the future.

About These Rocker Assemblies

Right now, what we can assuridly offer are the "younger type" rockers for three-piece case engines, 356 and 912. These were originally used on the S-90, C, SC and 912 engines and may be fitted to earlier engines with care to observe the valve spring geometry as sometimes a rocker arm can contact a valve retainer. (There are usually solutions for that.) Sometimes we have earlier types available, but we urge you to call or email us about that.

One thing we often can provide, but not all the time, are rocker arms for two-piece-case 356 engines. If that's what you need, please just contact us.

AT RIGHT: The sharp-eyed observer can see the "step" in the contact face that's discussed in this page. In particular, ALL of the "upper" rocker surfaces are significantly damaged, and only the one lower arm appears to be OK. This is a typical circumstance. But there are FAR worse examples than we show here... We just haven't taken a lot of photos of them!

For sale outright, we are ONLY offering rocker sets that have been serviced and are ready for use - we are NOT selling cores! That said, we ARE selling complete sets. Or, we'll service your cores, if you want.

AT RIGHT: Here we easily see the gap above the valve where the whole right-hand side of the valve stem is NOT in contact with the rocker. This is the kind of problem that our solution solves.
