Oil filter housing leaks

[AA91]

I'll try to keep this short. I bought this car a while back. Iv noticed some small oil spots on my driveway for a little while now, and after changing my oil the other day I noticed where the leaks were coming from. I assume these fittings are either wrong or loose. ( circled in red 1&2 ) I also noticed oil on the bottom of the oil pressure gauge sender, tho I'm not certain if that is a problem on its own or if oil has just ran down from the other leaks. The stock oil pressure gauge hasn't worked since I've owned the car. I've added numbers to the image for easier classification for anyone that may be able to help explain. I plan on adding an aftermarket oil pressure gauge in the coming weeks. Any information is appreciated! Thanks.

Actually several spots to leak around the oil pump, so it's hard to exactly distinguish with a pic. But judging by the pic, looks like the oil cooler block off plugs are suspicious (#1 and #2). #3 is a common location that oil stay because oil go down along the wire. Just check the block off plugs if they are sealed well because I see no washers. If they don't have any sealant on its thread and if they are without a washer, then could be those plugs are the cause. Put some aluminum crush washer and see if the leak would stop. The plug is M16 x 1.5. And should clean around the oil filter housing, so it would be easier to find when it leaks again.
P.S. Since your oil cooler is canceled and its ports are blocked off, you should also make sure if the bypass valve (the green circle) is not disturbing the oil flow. When you have time check and refer the last post (#22) in the link below.

Alright I'll be sure to look into everything you mentioned. I think I might need to just replace the block off plugs because they are a bit stripped looking, so might be a bit of a pain to remove. Newbie question here, but I've never taken apart anything on that housing, do I need to drain the oil to do said things? I just changed the oil less than a week ago .

No, you don't need to drain. But you may drop some oil that remain in the oil filter, the housing and the oil gallery, so just put some tray or container to receive it. But it's just a little bit.
Just be careful, do not let any dirt or any objects into the housing, where the two block off plugs is post oil filter, so nothing would filter it and it directly goes to the main oil gallery and possibly damage bearings.

Alright, I'll look into it this weekend. Thank you very much for the information, very much appreciated!

You need a line to run between those two ports, blocking them off like that can starve your engine of oil.
