This was a Facebook market buy, not sure why she did that.
Anyway, I found the Cap to be bad around 90c and would leak from there.
This was due to overheating and also found the thermostat to be bad adding to the issue.
This also included a small leak from the thermostat housing which only occurred at high temps.I hope this helps if you have not resolved this yet and I agree with (Speoccou), check your whole water system to be sure.All the best.
