W211 e220 cdi, I have had oil in the bolt hole one cylinder, cleaned out and put some air pressure down and now have a coolant leak from the bolt hole. Can I plug it or do I need a new engine top block or new head gasket?
The bolt may take 5 turns without breaking, however when injector combustion sludge starts leaking into the bolt hole is what causes to break when removing from factory torque.
That bolt took 8nm plus i counted atleast 7 lots of 90. But remember you didnt have the copper washer on the injector. So it would have snapped probably on the 4th lot of 90. 👍

This is just an experiment showing how much torque can these bolts actually take lol

very helpful information, i always afraid to break it
Nice video, but it is 7 Nm+ 90 +90 by WIS, not nice to break it in car
