I managed to fix it. The old gasket oring was stuck to lim. Didnt notice. so now it doesnt leak which is good. But my heater core has air. Supply line is hot return isnt. So last night i took both core lines off flushed it good. Made sure both lines has coolant before attaching them. Still the same, one line hot..... so i let it run for awhile bleeding it a good 12 times. Not too make things worse but i took it out today and now theres a high idle. Didnt touch iac or maf. I dunno man,
