Question Oil leak near oil filter

My recently acquired MY02 WRX wagon has a very slight (but messy) oil leak. Slow enough that overnight in the garage it doesn't actually leave a drop on the floor, but it is clearly a mess underneath. Both valve cover gaskets look messy, I plan to replace those, but I'm wondering if this mess around the oil filter is a different leak? It appears to be coming from above the filter, are there any common leaks in here to look for before I tear it apart?

Thanks.

Check around that cooler and the hosing on there. Cracks or tears in it. Spray some carb cleaner and get it really clean and watch it for a while.

Non running to see if it leaks

If not start the car after ya clean it and watch for some leaks

Mine does that too...very slight weep. Not hardly enough to notice on the ground until you crawl underneath. I've been trying to locate the cause of this issue as well.

Mines the exact same and after research i found it was the oil cooler gasket/ o-ring. I havent replaced it yet but plan to. Apparantly its pretty common on these cars so Id say thats your best bet

Replaced mine. I read somewhere it was possible to get that gasket out without removing any hoses. I tried this and even made a pic from a bicycle spoke to get it out. There was only like an inch of play, and I could feel the gasket with a finger and pic, but it was in good. While wrangling the oil cooler it popped off one of the hoses. Luckily I had a couple sharpies for this, plugged the hole, and easily removed the gasket. When you put everything back together be very careful to make sure the new gasket seats right. It will pop out of the groove easy.

My 02 leaked in the same spot. I did replace my gasket and it wasn't too bad. I did pull off one of the coolant lines and got a bucket to catch the coolant. one thing to try before you replace the gasket is pulling off your oil filter and tighten up the bolt that is in the middle of the cooler.

yep the orange o-ring between the block and oil cooler ..this happens a lot . easy to fix if you have the right size sockets ,and you'll have to drain you coolant .should replace those coolant hoses while you are there.
