Well after worked today.. I drop buy the Auto Store and picked up Some PB Blaster for the Crank Bolt. I sprayed some and let it soaked before I impact it again for a good 5 mins. Still nothing. Im not sure where I can rent a Heavy Duty Electric Impact gun..Are they expensive to rent? Or should I get that Tool from PowerTool that hold the Crank Pulley so i can take off the bolt with a Very Large Breaker Bar...

 

Are you using an extension with your impact? Don't. Get a deep socket if you need the reach,but an extension will lose lots of torque from an impact wrench.

Does '93 still have the timing inspection hole in the bellhousing? If so, you can get a crowbar to hold the flywheel. Need another person to hold it good, but you can use that while wailing on the crank pulley bolt. Careful; if the crowbar slips you could chip the starter teeth of the flywheel...

 

No extension on the impact. Yes there is an inspection hole in the bell housing where the rubber plug go..

 

crank pulley bolts are not reverse threads no matter the year
