I pulled the threads in the upper-right bolt hole in the block that receives the front engine mount. This hole seems unusually large for its bolt size (M10x1.25, apparently). It is as if it has been designed extra large to allow tolerance for inserting the bolt, and seems like the threads start part way into the hole by design (I can't tell, since the threads are damaged). The M10x1.25 Time-Sert bushing I have slides right into the hole, making it clear it won't work...unless, again, the bolt is designed to sit deep in the hole. I'm a bit confused by all of this.

 

It does sit deep in the hole... the smooth area just inside the hole opening is normal. I would time-sert the hole if I were you.

 

I had same problem. Buy helicoil m12 x 1.25 kit and repair
