nah, just get it in one of the bolt holes against the engine casing...so that you can pry... the bolts can't be on there with more then 70 some foot lbs of torque
If it doesn't come off right away, theres always WD40...

unless your bolts are rusted in 90 psi should be more then enough to undo those... Are you trying to hammer them off?

Ive heard of people not even being able to crack the crank bolt with a heavy duty 900ft/lb impact. Breaker bar w/ pipe is the best way!!!

That bolt is hell. I just cut the cover off my car so I will never have to take that damn bolt off. I have heard people jammimg ---- in the crank(with the oil pan off of course) and using a breaker bar. I have also heard of people taking a sparkplug out, dropping a rope down into the cylinder and cranking the motor by hand until it stops, then cranking on the bolt. I would not do that, but I have heard of it working. Just cut the ------- cover off so you don't have to deal with it ever again.

get a braker arm drop the car down let the braker arm lean on the floor and crank your engine.
That should do it.

well see my motor is on an engine stand..its not in the car...is it safe and ok to cut off the cover ??well atleast a portion of it that covers up the belt around the crank pulley ?? cause i could do that...but what about my flywheel ?? maybe ill see if i can borrow a bigger impact gun for those cause i cant take them off with the engine on the stand.
