snapped bolt on cam bracket

[GDZ1LA]

i have has nothing but trouble with my rb25de cam caps, 25/28 of the bolts were totally seized

10 needed heat iswell to remove

1 snaped in cam cap on removal (e2)

i then tried to easy out, this was a waste of time ans a easy out,

i then drilled out tried again and it snaped the cam cap, can it be welded, or will it warp?

the rest need leverage to remove,

one bolt snaped in head (8.7ft lb) (e1)

easy out worked,

and i striped tread (e1 iswell) i trilled down deeper and taped deeper, and used a longer m6x1 bolt, a little swarf went down hole into head, bugger alloy and magnets dont work, any suggestions?

so after all this muching around (6hours) i need 2 bolts and a e2 cam cap,

so if anyone rebuilds a head DONT acid bath the caps with the bolts in, remove them when you take cams of!!

otherwise your in for alot of muckin around with a hone and wet n dry 4 bolts!
