Not oil. Put it all back together and ran it on pre-mix 50:1 in a garbage can. Ran about 5 minutes and the alarm went off. It never registered water pressure on the gauge. The outlet for the water pressure tube is downstream of the thermostat. So either thermostat is not owning (which thermostat is good, I tested it in a small pot on the stove) or in just not making, or losing water pressure.

I'm tapping out and taking it to a mechanic next week. Hopefully all the things i have already done can help speed things up for them.
