Valve adjustment with swivel foot adjusters Options

[Geezer914]

When adjusting valves with swivel foot adjusters, are you adjusting them with "0" lash or .004 that Porsche recommends? My thinking "0" lash does not allow for heat expansion and the valves will not fully seat. (IMG:style_emoticons/default/popcorn[1].gif)

If you have steel cut to length pushrods you can adjust your adjusters to 0 lash.
If you have aluminum push rods you need to follow the factory specs.

It has NOTHING to do with swivel foot or not. It has everything to do with the expansion rate of the pushrods VS the expansion rate of your cylinders.

Elephant foot adjusters expand the contact patch of the adjuster and (in theory) keep the adjuster from wearing away. They usually are not used in otherwise stock builds, and using inferior swivel foot adjusters (ie - most of them) will eventually be the cause of failure in your engine. Therefore, unless you are building an engine with upgraded valvetrain, and steel custom pushrods the cost of the good swivel foot adjusters ($20 per adjuster) usually isn't warranted.

But valve lash has noting to do with the adjusters and everything to do with the push rods.
