L5 Turbo, L9 Turbo and now - L What Turbo????

In my earlier post http://kp-gasket.blogspot.com/2010/09/another-type-of-jb-det-rocker-cover.html which I found interestingly my stock of L5 and L9 valve cover gasket can't fix into this rocker cover.

This engine actually is from the same family of Daihatsu JB series 4 cylinders engine which all of them share the same cylinder head gasket.


At last I have the rocler cover gasket in my stock, but what should we call it? L5, L9 or L whatever, but owner need to be clear of which type of gasket they really need it to avoid wrong item been ordered.
