im starting to put my cossie lump back in,on a 200 block on the turbo side at the back of block .there is a screw thread hole just above the sump ,whts it for ???
a wire is normally fixed there with a screw and a clamp in it but most peeps drill out thread and vent there breather systems back to sump through it by drilling a hole
If it's the hole with the fitting in, as shown below, it's for an aftermarket breather.
If it's the hole slightly above and rearwards without the fitting in, it's for draining coolant from out of the block.
