When doing my timing belt, Everything went smooth until i got to the crankshaft pulley bolt.
Crankshaft pulley bolt, Man i have tried everything.

1. 8' breaker bar with 4 inch pipe extention.
2. 1/2 impact gun 230ftlbs torque
3. using the starter to bleep the bolt loose.
4. bolt drenched in Pb blaster, Wd40, liquid wrench.

I've broked two sockets, 1 great neak, 1 craftsmen. right now i've got an impact socket holding up.
Yea, i finally got it off w/ the oem pulley holder, 1/2 breaker bar w/ a long long shop jack handle (if you spread your arms out it's about 3/4 that distance). i eventually created 515ft lbs of torque.

Took me.. 16hours, 8 hours of it was just trying to get that bolt off. I finished and it runs like a champ.
