You’re probably going to have to replace the whole line. You could rebuild it, but make sure you use hose that is rated for oil. Heater hose “sweats” and makes an awful mess.
There are writeups out there. I think the main one that is linked is on Volvospeed.

You indicate the return line from the cooler. I don't know what pressure it is actually subjected to, and this type of line can be repaired using hose and worm-type clamps, but it is your engine's oil line, I would have the line rebuilt by a specialist, or replaced with new.

#3 is the inlet hose
#7 is the outlet hose

You will probably also want to replace the o-rings at the oil cooler thermostat, down under the crank pulley, and the square gasket where the thermostat connects to the block.

Replacing the oil cooler lines is a PITA. Because of that you may want to just replace both lines, that's what I have always done when one needs changing, but of course these lines are expensive.

Ouch. Well, at least you can rest assured that you've got new OE parts in there!

Well, seems like I misfitted the thermostat gasket...
Any tips on how to make it sit in its grove?

I haven't replaced my oil thermostat gasket, so I'm not sure exactly how it will sit in place, but some petroleum jelly around the edge usually helps gaskets stay in place.

That square gasket is a nightmare IMHO. I don't remember the exact tricks I used but I would get it squeaky clean and then try a little RTV to hole it in the groove.

It is very easy to bend the aluminum thermostat so that the gasket doesn't seal, make sure the face is totally flat. I bent one during installation despite being careful about it, and needed to use a board to flatten it out.

The thermostat is tricky and it is easy to cut the O ring when reassembling it. The square gasket is tough and, unless there is a visible problem with the old one, I just re-use it since it retains its shape. The sockets on the oil thermostat must be surgically clean when you insert the lines.

The bracket is also a bear and I have found that removing the air conditioner compressor bolt that blocks the straight shot to the bracket bolt will give you a access to it and the bracket bolt will go in effortlessly. I use several extensions stacked up to get past everything when dealing with the bracket bolt. Getting the air conditioner bolt out is its own special project but if you have an air ratchet it comes out and goes back in quickly.
