A quick update, deMort is right, these studs are a right PITA :sad:
I picked up some long series HSS drill bits after work today and they wouldn`t even look at the studs, even though they rust away in the blink of an eye they are very hard steel :?:
I carried on with my carbide coated jobber drill bits and managed to drill the bottom most stud out ( albeit at a slightly jaunty angle ) and put a cap screw, washers and nut either side and tightened the flange up.
I took the car out for a VERY spirited 30 minute drive through some local lanes and it all held together and nothing blew apart No blowing, no EML, all was well.
I`ll be out with the local guys tomorrow night, Mr Chief and Paul ( the organiser of the trackday and owner of Zuffenhaus Porsche ) and discuss the situation with them and if I should just drop it in to Zuffenhaus and get the manifold bolts replaced ( depending on their workload ) or continue on and get a dremmel on the last stud and get it all done DIY stylee :grin:
Quite how Porsche bolts can rust away before your very eyes, yet be so hard to drill out is a conundrum to me :judge:
Cinderella will be going to the ball though
