ok, well..found out one thing, small hose on the thermostat housing was rooted, ended up blowing a hole in it, so wasnt holding any pressure, replaced the hose, put chemiweld in, starts bubbling at around the p on the gauge, cars running awesome now, no more idle hunting either, but hg not looking good :blinks: time to send the head away to be shimmed etc an head gasket replaced :lol:
cheers for the help guys
