Ok long story short, car severely overheated, so much so after opening the oil cap there was smoke coming out from there as well, the pipe from radiator going to the trans thermostat came off. Its been a week since and I'm still not sure if the head gasket is gone or now.
There is no sniffer test available so I have to go on my own diagnosis. Car does not overheat, thermostat is not an issue, fan, rad etc etc but seems to me the system is getting over-pressurized but holds the pressure for more than a day, as in if I let it cool down overnight and then the next there is still pressure in the system. No oil in the coolant but can smell some new smell in the expansion tank every time I open it.
Maybe I'm not bleeding the system right although I've had Land Rovers and Range Rovers for 10 plus years now and never had an airlock issue, and am following the official procedure of refilling as mentioned in Rave. I did see coolant seeping out of the expansion tank when at temp and hose pipes hard but I am thinking that could be because I overfilled the tank.
I can hear and see bubbles along with coolant when engine switched off after a drive and I loosen the bleed screw, and takes a while for only a steady stream of coolant.
Temp doesn't go over 100C but pipes are rock hard and I don't drive it for too long fearing I might blow. But it drives just fine temp needle stays in the middle and the secret menu as well as the car soft ( no codes btw ) always show temp below or close to 100C
So no overheating, no steam from exhaust, no oil in coolant, holds pressure overnight just over pressurized ( or what i think is over pressurized )
I read in one of the posts while searching that it has taken some people a couple of days to get rid of all air the system, drive a few miles, the bleed the air from the screw, repeat this over a couple of days, maybe thats what I need to do to?
