I guess it's possible that I have oil in the coolant...seems more like rusty water at this point though. Or tiny amount of oil if that's what' it is.. oil cap looks clean though, so no coolant mixing there far as I can tell...
I did take thermostat out for the first 4/5 flushes and then started experiencing the above mentioned issues...so today I put it back in for another flush, and same thing is happening.. getting car to operation temp running for a few more minutes and turning off, and overflowing like crazy.
I did bleed the air out today. Maybe not every last bubble because it was taking a while and I got worried it was going to bubble over out of my leak proof funnel again. So I bleed what I could then let cool down, bleed some more and capped radiator. Let idle for like 20 minutes all while watching a ton of bubbles still coming up on my reservoir. Then turned engine off, and overflowed out the reservoir again. Something ain't right here...gonna get the block test kit I guess?
