Default Throttle body gasket

So im changing my throttle body and I noticed the gasket is wet and smells like oil and coolant.. Its obviously been leaking. Ive thought for the longest time this leak was caused by my EGR delete plate not being sealed but turns out its the throttle body>supercharger joint.. Ive ignored it because its such a small leak that the level hasnt even gone down in over a year..

Would you think this is just because the throttle body wasnt tight enough (it felt like the nuts were a little loose)?

My main concern is, can I reuse this gasket or has the leak ruined it? It looks to be in good condition but... I also have the green coolant in there.

AND im wondering if the throttle blade should create a seal inside the throttle body or is there supposed to be a (tiny, really tiny) gap between the blade and throttle body housing? You cant actually see the gap unless you hold it up to a light.

Thanks much!

I don't like to reuse gaskets unless they are the metal ones or it truly hasn't been long since I've removed an item, they're cheap enough that I replace them when I pop apart things.

And yeah, a little gap in the blade is normal.

And regards to the coolant, it shouldn't be from your EGR blockoff, coolant does flow through the TB on these cars, you can block that passage no problem if you want. Mine is blocked off.
