I started to install the Oil pan onto the engine block, the tool I was using was this;

I was using this torque wrench to torque the bolts on the oil pan to 20 Newton meters (15 Ft lbs). Turns out this torque wrench is to old and became faulty.
The result is this.

A screw that broke in half,  sucks, so to everyone wanting to trying an engine built...make sure your tools aren't broken, lol.

I will make another post when I figure out how to fix this problem.
