Yes and I sympathise deeply. However the fact remains that if the bottom hose is cold there is no circulation. Even though you've replaced the thermostat, if K-Seal remains in the system it will contaminate the new thermostat.

Other people have had exactly the same trouble as you are experiencing. A member called Trevor, who I don't think is an active member any more, did countless flushes on his engine in an attempt to rid it of the devil's potion.

This is why it is irresponsible to use or recommend this stuff. But the problem is that people are attracted to quick, easy and cheap "solutions". Unfortunately K-Seal is not a solution.

Regarding an air bubble, you can address that by draining the cooling system fully and refilling it following the MG Rover approved method.
