pretty common thing in landys, had to put the front wheels on a four post hoist and raise it to about 30-40 degrees to try and bleed the air from the heater core all the time where i used to work! after coolant changes mostly

pretty common thing in landys, had to put the front wheels on a four post hoist and raise it to about 30-40 degrees to try and bleed the air from the heater core all the time where i used to work! after coolant changes mostly
Ok its just getting worse!
still got the sloshing noise in the heater box after bleeding it again and again with the car on my steep drive way and a jack under the front (radiator was chin high) still no change
things i have noticed
after a normal or long run i hear hissing from the expansion tank. tank seems fine so i have replaced the lid and this fixed it for a little while but its back again.
temp got high at the car wash the last night(less then a 1k from my house and it was very cold) radiator temp was below 20deg but i did do and big engine wash so i probably earthed the sensor and the engine wasn't very hot to touch and 10 min later it was below 1/2 way
no heat in the cab till i start to drive then when i come back to idle for a few min cold air starts again
pulled the radiator drain plug and the coolant was very air rated.
So i think either the HG is going/gone (errrrrrr) or i have another problem or a blockage of some sort that is stopping water flow and the no heat in the cabin is a dead give away of that.
I have done a sniffer test (blue liquid) 4 time now and still nothing its getting to the point when i out the sniffer in the expansion tank i don't even have to pump it bubbles just raise in to it but the liquid doesn't change colour!!
Everything seems to be pointing to a HG which means the one i replaced 12000K ago must have been faulty or the guys that rebuilt the head f&*ked it up
anyone go any more ideas or tets i can do before i start pulling it apart?
Cheers
Mick
You might remember my comment about my bro ....Quote:

Also ... Check the hoses going to the throttle body for leaking ... especially the 2 little ones going to a thin plated body .... Take the little hoses off and make sure they are running OK (coolant) through the throttle body
Other than all the above ... The hissing from the expansion cap don't sound good tho

Infact ... If you have done the sniffer test (blue liquid) 4 time now and still get nothing ...
first port of call .... Disconnect the heater hoses from the heater box .... Cheap & simple to do .... and less things to blame

of course this wouldn't be linked to you getting hot and cold air...that could be a coincidental issue. might be worth a look
I am 100% that is is from the hear/cooler unitQuote:

I have just read this post and found this could be the cause the of my problems.
1 On startup my heater core seems to "slosh"
2 the heater does'nt seem to heat up as quick as my other old disco
3 i have had my radiator reservior split recently.
4 it seemed to overheat when i climb up a big hill near where i live in the summer. but did it again tonight even though it was cold
5 today it has just started to use oil and is fuming badly out the exhaust, lost power and has a clicking sound coming from the engine. also appears to be running on 7 1/2 cylinders.
It now appears that i may have a blown head gasket. thanks
This can frequently indicate head gasket problems,not just in Landrovers but other cars as well.
if the gasket is leaking, combustion gases aerate the coolant.
It is happening in other parts of the system,but because the heater core is up close it is easy to hear.
Excessive header tank pressure/and/ or loss of coolant are further indicators.
