i am in the middle of doing mine ... i had 4 broken in total , two were broken and two broke while undoing the head stud nuts .. all 4 were lower Dilivars.. and they were a nightmare to get out . needed tons of heat and a collet. i was releaved when i got 12 out. I am not touching the upper 12 steel ones.

anyone report of steel studs pulling out of aluminum case ? i am assuming most of the pulling studs issue was fixed with the aluminum case.

Looks like Porsche did a two pronged attack back in the day , went to aluminum case and the dilivar, but all they really needed to do was go to the aluminum case and stay with steel studs , and everything would have been fine.
