I can see one fatal flaw that is pretty obvious, when the FAV originally was built it had a rather small peanut fuel tank and no rack behind the seats.
The original design was a desert racer so it was supposed to be moving and moving pretty fast all the time, unlike most military vehicles.
So originally it would have some air flow across the external oil cooler, the original bug engine had an oil cooler in the fan shroud so it was in the air flow of the cooling fan all the time, that was eliminated when they installed the external cooler/filter.
After the large fuel tank and rack were installed there is no longer any air flow across the external oil cooler, certain death for an air cooled engine (most air cooled engines should more correctly be called air/oil cooled)
I of course am not the first to see this as the previous owner of my FAV installed a fan on the oil cooler, this is a must have item without a redesign of the oil cooler placement.
The former owner turned the cooler around and put the fan on the rear side of the cooler, I will turn it back around and install a smaller high performance fan on the front of the cooler where it will be less noticeable.
EDIT, so the stories of blowing one motor after another may not be too exaggerated, it looks like a colossal engineering failure.
