Hi,
Just got the radiator changed and bled, however I was told that there was still a slight bubbling whilst the car is running in the bleeding funnel. Is this definitely a head gasket issue?
I have never seen over heating and I changed radiator due to a crack in the OEM plastic. Car also had a rocker cover leak, no smoke from exhaust (Except slight puffs of black under boost).
I've been told it could be a water pump cavitation, but wanted to hear your opinions, has anyone else had that? 145000km
Thanks in advance.
