I was installing the knock sensors and the 1 inch nut which is at the bottom of the stud which the knock sensor sits on hits the block on the lower portion by the oil pan. The threads only go in about half way so it's not like it bottoms out. It looks as though when they tapped the hole it was done at a slight angle. One side is fine, the other the fitting hits the block before it gets mildly tight.

I can grind some metal off the stud so it fits.

The question is they make 1/4 mpt to 1/4 fpt short extensions but is that permissible for the knock sensor to work properly?
