General Ulysee Water Loss

[Alderman]

Have a P Reg Ulysee and have been loosing water, replaced HG and Header Tank. Water seems to be coming out of pressure cap which I have also replaced. Garage can't seem to find fault - any ideas?

Could be a cracked head. Theres a test for exhaust gases in the water system. Garage should be able to do that.
