With blind tapped holes, it can be difficult to tell when the bolt is fully clamped or out of threads.
Also, about the allen drive pipe plug in the injector housing coolant port; What if it's seeping coolant into the adjacent intake runners? How would you tell unless it was significant? There is so little "meat" there to tap for that plug. I have always been concerned about it sealing properly with probably less than 2 threads engaged.

Jerry,
Thanks for the tips on checking bolt clamping. The allen plug has been there now for probably 7 years. No indication of coolant loss so far. The dampness u see on the gaskets is of an oily nature
