This weekend while putting my stock pulleys on in order to put my timing adjuster on I some how screwed up the first couple threads on the bolt and hoping that it was just the bolt I got a new one. that was not the case, also the first few threads on the crank are done. I know this is gonna sound bad but right now it is together and the only way we could get it to hold was put in a course thread bolt but it should have a fine thread in therebut course is the only thing that would get past the first threads.it has held for about 150 miles and I have checked it numerous times and it is still real tight.

In order to fix this what is the best way? I have heard not to helicoil the crank because under high torque it will come apart. is this true? what about reverse helicoil? Now tapping is another option,do I have to drill all those threads out and tap all new ones? how hard would it be to hand tap the threads? how bad is it to drive this while it is half *** put together? it feels good and everything while driving and you would never know anything is wrong unless you put it together.

I would say go with re-tapping the hole. idk if I'd trust a heli-coil nor have I ever heard of anyone heli-coiling a crank. You could aslo call a Ford mechanic at a dealership.
