I replaced the orings on my Crown II. It still leaks. I even replaced the oring on the coil. I dont know what to do now.

I don't have the tank but I did decide just for fun cuz I'm not doing anything else to look up and see if there may be a resource or a simple solution and there are a ton of people online talking about various versions and leaking especially after a while everyone's first suggestion seems to be o-rings of course but there are other suggestions as well so I hope you can figure it out I'm sure someone will be along that actually has it and can tell you their experience good luck! It's always so disappointing when that happens
Leaking tanks are so hard to diagnose. Even if you changed the orings, doesn't mean they are the right size even if they came with the tank. I suspect the oring that seals the top cap could be bad (even though you changed it) or not the right size (needs to be sightly thicker). If it's not the right size, the next thickness up may not be the solution a sit may be too thick. SO if it is a 1.5mm thick oring, just changing it to a 2mm thick oring may be too thick. What you would need to do is go with a 2mm oring but with a smaller diameter so that when it stretches it becomes a thinner than 2mm but not as thin as 1.5mm. It can be really hard to figure out which size oring to use.
Another oring that may be faulty or the wrong size (of which they don't give spares for ) is the oring at the bottom of the coil head. It may not be sealing correctly up against the base of the tank.
IIRC, you posted about this problem a while ago but asked if thicker juice would solve it. Did you ever try thicker juice?

Gesh you can remember a post from 2 years ago? I cant remember what I had for breakfast. Oh right I havent had breakfast yet.
The reason I remember the post is because I have been thinking about going 70VG or at least 65VG. I'm a 50/50 vaper too. But I never tried it yet.
Also, another thing you can do to try to eliminate a leaking topfill tank is to just fill it from the bottom instead. Assuming your orings are all good, this can eliminate or seriously lessen leaking. Some topfill tanks are hard to bottom fill, but I think that Crown 2 will be easy from pictures I've seen.
Also, if top filling, don't fill it when the coil is still even warm. Wait until it's totally cooled down.
Oh no I have to wait until it's cool? What's one to do in the mean time?
You have plenty of tanks to not worry about this.
The original Crown tank has this problem with the RBA. If you fill it when warm, it starts leaking almost immediately from the airflow when filling it (top filling). Melo 3 is the same to a degree (with factory coils).
In my experience the older a factory coil is, the more likely it's going to leak. It can still vape well and taste good but as some of them get older, they just tend to leak juice into the airflow. It is what it is. But you have 700 of them so... 
(Old as in used-up, not old as in sitting in your vapocalypse closet.)

If I were you I'd try 70/30 juice. Just take our 50/50 and add enough VG to it to make it 70VG. Sure the nic content will be less and so will the flavor, but the idea is to just test it. Those coils may not fare well with thin juices. Worth a shot IMHO. Just take 3ml of your 50/50 and add 2ml of plain VG to it. That'll make 5ml of 70VG/30PG.
I've been doing 70/30 for awhile. No dice. Also bottom fill. FAIL. STILL LEAKS
