I know I know another annoying question but the search is mia.
I'm just curious to know if anyone else has experienced this. After driving, my antifreeze is bubbling and/or seems like it is boiling in the overflow tank. I have a fluidyne and there can be a few variables. I also forgot to mention that I am not overheating the temp needle stays in the middle.
My questions are:
1. Would there be obvious signs of a blown headgasket such as the red toyota antifreeze getting into the oil. (In my case no because I checked the oil).
2. Bad radiator cap/thermostat? Although I have a fluidyne I do not have a fluidyne rad cap it is a generic rad cap.
3. It has never done this before up until this week however we have been hitting 100+degree temps this week. Could it just be getting hot and I have air inside the system?
Other than that I think it might be a blown headgasket because I've been running it at the track. And I am running rich (10.9-11.0 AFR's) on 1 bar and pump gas but at the end of the night my exhaust tip is white as if there were a powdery residue on it.
I just want to get some opinions before I roll up my sleeves and tear the head off. Thanks for any help sorry for the novel, I wanted to be as specific as possible describing all my symptoms.
