I was reassembling my engine and while torquing the cylinder head nuts to 49 ft/lbs the stud stripped out the treads in the engine block half. I need to find out what size helicoil is needed to repair the threads. Is this common or do I need to have my torque wrench calibrated? The other three torqued fine. Just don't want to have to tear down again after I repair with the helicoil. Thanks

Yes I would get it calibrated just to be safe and I couldnt tell you on the bolt size but guessing from what it torques to I would say the bolt size is 10mm or 12mm but your thread pitch can be a 1.00, 1.25, 1.5 etc Hopefully someone can answer that for you better than me.

If no one knows, you should be able to take the stud to Napa, Fastenal, or a similar store that has a metric thread gauge. Fastenal could probably order you the metric heli coil too.

You can Figure out the Thread pitch if you have a Tap and Die set too... taking it to any Hardware store would work too...

Just wanted to get the helicoil before I tore it back down. I might just install helicoils in all 4 locations and use some thread lock. That should prevent this from happening again.
