Like the title says, my crank bolt won't stay tight. I tightened it 3 times before I pulled out the bolt and looked at it. It looked like it was the stock bolt and the threads were pretty worn down so I went to the dealership and got a new one, cranked it down with red loctite, and the damn thing still came loose after running my car hard.WTF?! By the way I have an ASP pulley on the car. Any thoughts, suggestions, or input is greatly appreciated!!

Are you tightening to 240ft/lb tight or just whatever my poor arm can do? New is 37ft/lb + 140 degrees, used is 240ft/lb, but I'd just go with new. Also no loctite needed. clean that crank out and try again. Use some motor oil to lubricate the threads, not loctite.

I just tightened it as far as I could until the engine turned. I had it on a lift and tried to torque it but I have no E-brake so the back tires were turning Any suggestions to hold the engine still?

I think you only can use the crank bolt once if you replace the stock crack you have to get a new bolt. i think ASP pulley maybe needs a long bolt or bigger. Buy a new bolt and torq it to specs and put some tread lock on it.

Can someone chimme in on this one

Correct that the stock bolt is a torque to yield bolt. Once it's been torqued down once, you'll have to get a new one. The ARP crank bolt is reuseable. Like already mentiond, pop the starter off and use something to hold the flywheel and torque it down. It may seem like a lot of torque, because it is.

Thanks for all of the input. I'm gonna put it back on the lift and drop the starter to hold the flywheel. Wish me luck!!
