If you have no idea when the last time they were changed is, then I would suggest changing the O-rings. It is a DIY job if you are mechanically inclined. You will also need to order new intake manifold gaskets and injector seals.
Also, is there an O-ring missing from your oil filler cap?

do not plug up the hose that comes off...if you want to reduce the oil in the intake system install an oil catch can...there are many threads on what to buy or how to do it

Alright, I changed the oil and there didnt look to be any bits of bearing in the oil, so i dont think i have spun a bearing. I also pulled the hose off of the radiator and there was no milkshake either.
So, what next? should i give the car a compression test? maybe the rings are starting to go?

Your next steps should be:
remove intake manifold
remove oil filler tube from block
replace AOS o-rings
at your next track day you will more than likely notice a decrease in oil consumption

Yes those are the o-rings that should be periodically replaced when leaking. I would inspect the oil filler cap o-ring to see if it has become brittle, if so, then I would replace that as well.
Spazegun, if you can remove the intake manifold then you will be able to see how the oil filler tube is attached (remember to plug the cylinder head ports after removing the manifold). Its held on by I believe three M10 bolts. When you pry off the old o-rings they are most likely very hard and won't want to stretch off, I would suggest cutting them off with a razor. Whatever you do be very careful not to damage the plastic tube. The o-rings that you order will seem like they are too big and are not the correct part, but in reality they squeeze in very tight and they will fit into the block. I'd first coat the o-ring in oil, then as I am guiding the oil filler tube back in place, I would push the side of the o-ring closest to the firewall in first and then use a blunt object to squeeze in the left half of the o-ring ( do not use a flat head screw driver, try something plastic with as much surface area as you can manage so you don't cut the o-ring).
Now would also be a good time to clean the ground straps that attach to the engine. First make sure to cover up the flywheel inspection hole! Also remember to replace the intake manifold gaskets and injector to maifold o-rings and injector protection caps. If you do not feel confident in removing the injectors from the fuel rail I would leave them in place, as long as they are not the original o-rings.
