How long a cheater pipe do you have on the breaker bar?



Oh wise ones,

I have now tried a breaker bar and a rented impact wrench, but I still can't
get any of the five bolts off the flywheel.  The impact wrench is slowly
chewing up the heads and the breaker bar just laughs at me.

The Bently says these bolts are torqued to 80 ft lbs but I don't beleive it
anymore.

Anyone have any final suggestions before I just sign over my first-born to a
mechanic?
