Cleaned up the block and ran a tap through the holes to clean them out. Put the gasket on, head on, torqued to 51 ft lbs and then re-torqued.
Now time for the 90 degree additional turn. Picked up a Torque angle gauge for perfection.
Got to about 80-85 degrees on the first bolt and. POP! Oh no. Pulled the bolt out and it was fine. Looked down and IT PULLED THE THREADS OUT OF THE ENGINE BLOCK!
Picked up a helicoil kit and fixed it.
Bolt torqued fine, until the 5th bolt and the same thing happened.
Did I weaken the threads with the tap? Maybe my wrench is off?
The first hole did look like the tap was off and cut into the main threads and took so material out but the other ones looked fine under a quick inspection.
I know I'll have to coil the 5th bolt but do I go ahead and do all?
Simple job is starting to look like a nightmare.
