Swivel Foot Valve Ajusters
Has anyone installed or used the so called "elephant foot" adjusters on a 2.0 litre FI stock motor. Can they be used without modification?

the best swivel feet to use are the Berg ones. Unfortunately Berg only has 8mm ones. So what I did was use the early rocker, which is 8mm instead of 9mm, and put it all together that way. Works great.

Did you need shims to adjust the rocker arm geometry?

The Berg adjusters come packed with shims and very concise instructions. Sometimes in the past , I have had to take .060 off the bottom of the threaded part of the rocker, which allows the adjusting screw more room, to get evetrything to line up correctly. I got that tip from Doug Berg, one of the Berg bros.

Ok..I am going to be the stupid one this time...are these hydraulic...i don't think they would be, but I am going to ask.
Also, are there any advantages to installing these? Thanks, Paul |

The rockers for #1 & #2 on my car have a little metal ground off the underside of the threaded area to line things up. I guess it is done quite a lot? The adjusters mentioned here are under the "valve covers" and the lifters which may be either solid or hydraulic are in the block and the push rods connect these two parts. If the engine has been converted to hydraulic lifters, it wil still have the adjusters, but not used the same way.

I have heard that the reason for running the swivel feet is to reduce the side loading of the valve in the guide. Thus reducing valve guide wear and freeing up the valve train. This can also be done with roller rockers, but at a higher price.
That is what I have heard. Can anyone verify? neil |

John and Neil, you guys have it right. This isn't a HP improvement but a way of reducing valve train wear. There is a larger, flat surface created between the valve stem tip and the swivel foot, with the Berg being the best at this. This reduces the side loading and decreases the wear on the tips. Also what you can do is use the late hyd. lifter rocker arm spacers on the early solid lifter motors and get rid of that spring between the rockers.
