Need to get the alternator pully off... Simple job eh, just undo the bolts... Yea, so I thought.
I went to undo the allen key bolts the idiot fitted before me, I sprayed on loads of WD40 yesterday to try and un jam them, the still rounded because they were so rusted, I drilled the heads off of them, but the person who owned the engine before me also decided to use a bolt that I can only get a spanner on, thats jammed in tight too, no chance of getting it un-done, so I went to drill that too, this bolt ended up being made from carbon stell and is just making my drill bits blunt...
How am I going to get this off???  I really don't want to take the crankshaft off, and I cant get the bolt un-done in the middle of the pully to just take that part off...
Any help PLEASE!

get a decent drill bit Ed.
drill of the heads, then knock the pulley off.
studs should unscrew easily then, using grips.

the splined bolts on the alternator pulley are truley awful, I changed all mine for stainless cap head bolts two weeks after fitting my engine and one of them was still rounded aftero only two weeks on. I got it off by drilling the head a bit to enlarge the hole and hammering in the next size up allen key bit, but yours sounds too far gone for that.

If it's hardened steel then a sharp chisel and large hammer will snap it off as the higher the tensile rating of the bolt, the more brittle it will be, give it a good smacking.
As for fixing thread A) buy a new one form autovaux, b) take to engineering shop.
Edd you still want the head rebuilt? I'm free in the week.
