Odd oil leak - assistance

[Richard Tanimura]

After a timing belt and v-belt change, my 3B developed a leak. I went in
again and found what seems to be the source.

There are 3 holes that do not seem to be threaded. I can't see what function
these hole fulfill. One is to the left of the cambelt idler sprocket. The
other 2 are to the right. All three were filled with oil.

- Is it the oil pump gasket behind these holes that needs to be changed? Do
I have to drain the oil? Any special tools?
