Coolant Problem!!!
Okay, so I've got a nice little problem that I need help with. I just replaced my heater core, got everything put back together, added coolant, started the car to bleed the lines, bubbles formed as per usual. Everything was fine, I drove around the block, got home and was letting the car idle. As it was sitting there I see coolant pouring out of the resivior and it was bubbling hot.
I shut off the car and let it sit over night. The next day I topped off the radiator and proceeded to rebleed the system. Only this time I let it bleed way longer, more bubbles formed, then I got a white foamy substance.
Bout 20min after the foam started, it stopped and it continued to buble up and overflow from the radiator. A buddy of mine told me to wait and see if the white foam became milky after it cooled. It didn't, it's like just grainy kinda like what ash looks like when you rub it between your fingers from a cigarette.
I've searched all day on here and read damn near 300 post about it possibly being a head gasket.
1. No milky substance in radiator.
2. No coolant on the dip.
3. No coolant on the oil cap.
4. Car idle's normal.
5. Temp reads cold at start up, then once warm it stays at normal temp.
6. The top rad hose is alot warmer than the bottom.
7. Replaced thermostat. (even though old one worked fine. Did hot water test.)
8. Took out all 4 spark plugs, no "sweet" smell or any sign of coolant on them.
9. Pulled off V/C all I see in new oil because I did an oil change at the same time I did the heater core. Stuck my finger in the little crevases and there isn't any seperation of the oil (if there was any water or coolant in there).
10. I double checked the Chiltins to make sure I put the feed and return lines where they were supposed to go when installing new heater core.
I don't know what else it could be. My friend told me the white foam could have been from the system just being gunked up or the new heater core just cleaning itself owt. I don't know what else it could be. Could someone please give me some guidance???!
