As some of you might remember, I designed a
vent mod system which screwed into the dip stick hole. The dip stick hole is a very unusual M14x2.0 thread. Well its not unusual if your a wheel stud. Anyway, the only fitting I could find that I could find off the shelf was a fitting from a Ford F150 radiator petcock. The modification to the petcock required the grinding off of the thumb tabs, drilling out the inside of the petcock and then running a die over the outside of the petcock so that a female barbed hose fitting could be placed over the top.
Anyway, this "white whale fitting" is off the shelf and looks looks it will only require a washer under it so it doesn't squish out the O-ring used to seal it.
If I get around to it, I'll take some pictures of the fitting installed.
Here is a link to the original development of the
vent mod.
