But rather than deflect, explain to me why no one else needed Dilavar, when the engineering and mechanical guidelines remained the same. And if Porsche engineers always got it right, then why so many different Dilavar stud designs.
And how come the IMS shafts were failing in 996s and 997s when these were designed with finite element analysis computers. No one is infallible.

Who else had air-cooled engines with same design and characteristics as Porsche engines? No one....
Also, Porsche to this day recommends dilavar head studs for air-cooled engine rebuilds. All the head studs have been superseded by the 993 Twin Turbo part number. I guess they just continue to be stupid....
