cant seem to find any recent pics (all the links are dead). been looking for this extra hole near original knock sensor to no avail. have the interwarmer off and can see a couple holes but they are the bell housing. are these the holes that are mentioned? does anyone have any pictures.
ps how do you add a pic

 

I used a hole on the other side of the block - took out one of the bolts for the intercooler bracket and it slotted straight in there.
