Hole in my Engine Block

I've got a question for all you smart LR guys out there...

If you look at the attached photos (of the rear of the engine) I have circled a hole in the block. This hole looks like it goes right into the water jackets. However, I do not remember anything that plugged into here. Am I missing a freeze plug, or am I forgetting about something else that goes here?

Anyone know what this is?

(The engine is a 3.5L V8)

The factory motor has a crank case vent there that has a tube on it that goes back to the intake on the CARB.

Believe it or not... I bought it with those valve covers on it. They were originally natural aluminum, but I had them powder coated black (but left the ribs exposed).

I do not know if those valve covers came on it from the factory or if they were an aftermarket add-on. The engine is from an '84 Defender that (I believe) came into the states through Canada. I suspect they were original, just because the engine didn't look like anyone had ever done a thing to it in its entire existence (to include oil changes) when I got it.

Thanks!!! I lost a lot of my photos from the tear-down in an unfortunate hard drive crash.

Those valve covers come on all the carbed V8's. They dont work on EFI motors unless you can do some modifications (never tried that).

Nice looking motor dude.

What mods would have to be made, I know a CARBed 3.5 thats near me, I might see if it is possible.

Never tried it but the venting system is different, nothing major I'd suppose. I know that when converting from carb to EFI I have been using the EFI valve covers but I'm not sure why. Probably just convenience and the use of std bits.
