All,

Following the Nissan guide on brand new head install (AMC Brand) torque wrench has 2 settings NM's and foot pounds as per the below set to 49 foot pounds (white spanner black background) now bolt thread appears to be broken looks like thread has popped with the bolt out and now it free spins? faulty head I assume or im reading this guide wrong ? 2010 CRD engine

Looks about right, did this around 2 years ago. Remove bolt and see what you get, you may need to lever the bolt head with a screwdriver while you undo the bolt. If it isn't to bad a helicoil may do a repair if a warranty claim isn't successfull.
Not good mate, sorry.
Wanted to make sure first and foremost I'm not doing something silly with wrench settings as long as it's in foot pounds and not NM on my wrench I'm following it correct I thought ? Bolt came out with thread in it sigh 馃槬 I think it's faulty ?
