I have repaired the radiator, changed the water pump. I bled air out with a radiator funnel. I also used the bleeder screws. Each time their is more air entering the system from somewhere. A pressure test shows no leaks?

Have a pro pressure check this for an intake/head gasket leak. Also look behind water pump for coolant and on other end of engine is same area. If you see it you need at least an intake gasket set
