Im trying to finish up rebuilding my motor today and I ran into a snag on my oil pump that I want to be sure about before I place the cover back on. I originally couldnt get my crank pulley bolt off so I had the guy that did my machine work get the bolt off at his shop and tear down that side. Now Im trying to put it back and Im not even sure if he gave me all the bolts. I have a manual but for some reason it doesnt address this threaded hole and I want to be absolutely sure no bolt is supposed to go in there.

here is a pic:


its the hole right above the one over my finger

 

i think those are just the cover holes, dont worry about it... if u have a few holding it in place you will be ok

 

Does it look like to goes all the way through to the block??

 

the ones to hold the cover are already screwed into the block (3 darker bolts screwed in). the hole Im worried about is right behind the plastic piece but there is no hole for a screw to go through it so I have no idea what the **** it could be for. I just dont want to get it in a run it and have my block pissing oil all over my garage floor.
