Why Would These Engine Block Holes Be Plugged
#1
My block is on the stand.

Removed the freeze plug that was pushed into the block.

Removal was much easier than I expected...once I got it unjammed.

I then removed the water galley plugs, 2 plugs with 3/8 square heads.

I put a 3/8 spark plug socket on the plug, then used the wrench on the socket to turn the plug out. The use of the driver side of the 3/8 socket idea was someone else's idea on this site, use of the spark plug socket for leverage was my idea. The punch is to remove the jammed plug from the socket.

The punchline: When I removed one of the galley plugs, I discovered in addition to the threaded plug in the drain hole, there was a mini freeze plug in it as well:

Question 1- Is this normal?

I then also noticed this plug:

Using the freeze plugs as an orientation guide, this is the underside/oil pan side of the motor, next to the bell housing, driver side with the motor oriented properly. As far as I can tell, the plug just seals up the bell housing area.

Question 2- This should not require a plug, should it?

Thank you.

(Sorry for the lack of beer in the pictures. Thanksgiving is kind of the mother lode of beer drinking days around here, so I did not have a "quality" beer for display. That does not mean I did not have A beer).

looks more like a broken off plug to me. Of coarse, could be the beer!

the "mini freeze plug" is maybe just built up corrosion.
I have never seen a plug on that bottom hole though, my 3 clevelands dont have them

Those holes are blocked to allow retardation of ignition timing.

Didn't see anything like that when I tore my H code apart. As midlife inferred, the retarding of the ignition timing may be related to the beer consumption. That's what he said, right? Tongue

Take a center punch and hit it in the center of the hole. Be sure to keep a good grip on the punch. If it goes through, GREAT!. If not, use the punch mark to start drilling.

On the water galley plug, I did end up drilling it out, and then I tapped the hole. So that wasn't that big of an issue.

And the second one...still don't know about that, but it is gone now.

Thanks everyone for checking.
