Removing crankshaft bolt. The 22mm one... I'm using a wrench and about 3feet of 318is exhaust as a breaker bar, but it will hold there until i flip the engine block. I've soaked it with PBlaster to no avail... anyone have any tips? I have the bare block with just pistons and crank in it, sitting out of the car. It's getting a little annoying! I'm just trying to get the pistons and rods out but the crank is in the way, so I need to pull it.

are you using the crank tool to hold the harmonic balancer in place?

that will help considerably.

I jammed a bar between a few flywheel bolts and the block so the crank is not spinning, but the damn nut is definitely not coming off. I've only had to break the crankshaft nut off cars 2x before in my life, and both of those were battles but much easier than this. Is it normally threaded? Lefty-loosey? I'm at my wit's end lol.

Impact wrench is your friend.
Buy one from the local sears, use it once and return it if you "don't like it".

Come on, you can get it. Place an 8mm drill bit or flywheel lock pin in the lock pin hole just under the starter motor. Then use a big breaker bar - 1/2" and 22mm socket. Don't use piping its useless, it just slips.

is your engine on a stand? If so, the flywheel lock pin idea won't work. I'd recommend a flywheel lock that bolts to the backside of the block. I don't have one so I turned the block upside down, wedged a 2x4 inside the crankcase between the block and crankshaft, then used my jack handle as an extension on the 1/2" breaker bar.

The flywheel pin will work. Thats the point of it - to prevent the crank from turning hence if the crank does not turn you can loosen the bolt.

Also have you tried the starter motor trick.

Ya, in my mind I was picturing the flywheel off. Then for my comment it's magically back on. Double duh!
