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)

So you are saying chrome moly pushrods don't expand? Every solid lifter engine I have owned specified a valve lash?

Not trying to beat you up on this. Just wanted to post the why . . . which you already got.

Over the years, the biggest mistakes I've seen associated with any type of air cooled engine is to associate them with generic water pumpers.

So many things are different about cooling with air (and oil) vs. water cooled lumps of cast iron that were so prevalent back in the good ole' days.

Ignorance of these differences is why so many pulled the cooling vanes and thermostat thinking that would result it better cooling - never bothering to see that that they had taken air away from the critical oil cooler.

Same kind of thing with lugging engines. Many VW's have died early due to "Luggers". Invariably they had a well meaning friend or relative that told them reving an engine shortens engine life. But what they didn't realize is that air cooling needs air to cool with. And . . . that air is moved by a fan directly or indirectly tied to the crankshaft. So too few Rev's = poor cooling and shortned life.

Or they get freaked out by all the normal operational noises that are so much easier to hear on an air cooled engine.


But all those unique things are why I (IMG:style_emoticons/default/wub.gif) air cooled 914's! They were truly different.
