Sorry to bring up a dead thread but felt what was close to the discussed topic. 

 

When i got my series 1 a number of years ago It came with one of the early valve covers. With it also the 5 pointed cap show in an earlier post (also picture attached). A friend recently gave me an elephant cap but it doesn’t have a seal with it and sits kinda high. Which cap would be better in terms of originality?  

 

Note that your valve cover has a O-ring seated in it so you will want to use a cap that snugs up to that ring for a good seal (no seal on the cap).  Later model valve covers did away with the O-ring in favor of a seal on the cap.  My OE cap has the same shape (6 protrusions) as your second pic but no elephant, only the word OIL, my valve cover also has the O-ring seal.

ok thanks for the info didn't know if I had to have a rubber to rubber seal. the 5 pointed can does have a rubber seal on it. 

The OIL cap, as Jim pointed out, is the correct cap for that valve cover.  Both of your's are not correct.
