The left side is flush, but the right side slipped in a little bit. I put goop all along the edge, then once I placed it in, i gooped it again and smeared it around.

You are right it is cocked in block. It can come back out. Not worth the risk. You have another Plug handy use it.

got a new plug put in this evening. A little cleaner and a lot straighter too. How long til I can fill it up?

Also, how much pressure will this see? I feel like the previous one came out rather easily. But the instructions say only two full turns and no more.

Pressure test after 24hrs @20 lbs press. with eng warm and filled with coolant.

Pressure tested with engine cold up to 18 psi before I had a small leak on the upper hose. I'd better let the thermostat gasket dry fully too. I'll test it again tomorrow. How long should it hold pressure for? I had it on for about 5 minutes and it held constant. No sign of leaks at my freeze plug.

Mission complete, Very well done. Good to go.

Tested it again tonight. No leaks. Held 18lbs for a good ten minutes. Took the tester back to O'Reillys before they charged me an arm. Then I ran the engine til it was good and hot. Still no leaks! I could tell there was good pressure by squeezing the upper hose, radiator got hot enough where I didn't want to touch it, so that concluded this evenings test.

Now I'll have to drive it on some short trips before I really get over my paranoia of it bursting, lol.
