what to do with this ceiling gap?

My other half of finished garage looks like this. Wondering if I should just do spray foam using a Big gap filler foam or just leave as it is. Looking for recommendations please. We have one of our upstairs rooms right on top of that ceiling.

I second the suggestion to put the foam backer rod shove it inside the gap and put some caulking around the outside of the seams

You mean just lay this rod inside and push to some extent and then leave all other inside parts as it is unsealed and then apply caulking outside ?
That's the right product. You size the backer rod slightly larger than the gap size. The backer rood acts as support for the caulking (https://conspecmaterials.com/shop/backe ... -the-foot/). Only the exposed side of the backer rod facing the garage would have caulking applied.

Regardless of how you do it, the idea with a garage is that it's more or less air tight relative to the interior of the house. You don't want fumes entering the house.

You don’t need anything where the drywall meets the blocks/beam. Foaming it is just a waste of time and money. The blocks are supporting the brick above. There are no gas fumes going into the house.

It’s an eyesore.

You can build a false wall in front. Or laminate some drywall onto the block. Use corner bead to finish. Put some mud on. This I would do…..

If you're going to go foam backer rod and caulking, then you might as well drywall over that piece of ceiling where your garage door opener is attached.

No harm doing it as it's a relatively small weekend chore to keep busy, knock it off and move on to the next issue that irks you every time you walk by it.

Actually I can. I will write slowly for you.

Look closely at the picture. Are you still with me?

You will see someone ripped off a piece of tape along the corner of the beam and the block wall.

That’s called “gas proofing”.

Unlike you…..I know what I’m writing about.

So am I not supposed to seal that area now or caulk? What exactly should I do?

BTW, I'm not parking my car in my garage and my car is parked outside all day as I'm using garage mainly as small home gym etc. So in this case, can I safely seal all gaps inside?

Do you ever notice water dripping from those drywall joints?

LOL - pretty big assumption from a single photo showing a short section of tape. When you've inspected the entire garage, feel free to let us know that there are no leaks between the garage and the house.

Unlike you, I don't make absolute assertions based on limited evidence.

I can explain it to you but I can’t make you understand it!!

Isn't the vapour barrier supposed to be on the warm side of the wall/ceiling assembly?
If you also seal up the exposed cold side nice and tight, then aren't you making a mould sandwich trapping moisture inside the wall/ceiling.
I would think the only reason to do anything is to keep rodents out and make it less of an eye sore.
