I've noticed lately that my coolant resivour is full of bubbles when the car is running; cold and warm. I've bled the system multiple times and usually the coolant buzzer goes off after I've drove for a little bit, but I see all these bubbles and it sort of makes me think that my engine is finally ready to go. That and the overfill cap on the res. has been shooting out gas/oil/antifreeze mix badly.
Is there anything besides my coolant seals that would cause all these bubbles/gas/oil in my antifreeze?

 

it's very likely that the engine is done. next time keep better maintenance on the coolant. it needs to be replaced regularly so that corrosion can't eat away the irons and expose the seals.

 

take the cap off the radiaitor and look at your water/coolant while running. if its bubbling, 99% of the time you have a bad water jacket. meaning, you need a rebuild. just hope the jacket seal itself didnt rot away from running water only... then you need a new iron.

 

Bought the car thinking it had bad coolant seals. My brother had overheated it whenever the radiator cap failed.
Anyways; I just thought maybe there was something else that could cause it.
