[V8] Timing Belt-Carlisle is slipping away

[d saad]

I don't know what it is with these bolts, but this seems to be a
common problem.
They seem to have a smaller than normal head area.
We have to stress that only a high quality 6-point socket be used on
these to any t-belt newbies,
and you must have the socket squarely
over the bolt head.
This should be added to any t-belt procedures.

On your problem Lanier, have you tried a 6-point socket?
Here
is a thought - I think a 1/2 inch is slightly smaller than a 12mm. If you
have a 6-point 1/2" socket and a hand impact tool (the kind you
strike with a hammer) maybe you can force it out that way. The impact will
help to break loose the threads and with luck, the smaller socket will
bite the head. 
The same technique works wonders too for the torx
screws on the water pump. 
I use a 1/4" drive breaker bar with
the torx bit. As I apply pressure to loosen the screw, I tap the breaker
bar. I never use enough pressure to strip the head - letting the hammer
taps break the threads loose.
The only caveat is that you can not
just beat the snot out of it with a sledge hammer.
I think Newton
said it best - for every action - there is an equal and opposite
re-action.
In this case, the reaction will come from your wallet.

On re-assembly I used anti-seize on all of these bolts.
