snout on crank stripped out

[datenbrick]

what do i do when the snout in the crank is stripped out, motor is in the car?

How did this happen?????????

I doubt you'll be able to helicoil such a critical fastener? Crank is probably trashed.

i wish i knew,i had it rebuilt a few years ago,just going to use it now and just another set back,oh well

Drill it to the next tap size and thread it. Done deal. Doubt you'll want to do it in the car, tho.

Send me a PM and I will give you a few options. A heli coil will work, but dont know if you can get one long enough. A crank bolt only holds things back, it does not hold up and down. The snout is where all the strength is at. Next size thread will work also.

Thanks

True but it's torqued to over 200 ft/lbs. That's a lot of load for a heli coil.
