Re: water choke
Are you possibly talking about a "thermostat" here by any chance? Perhaps the thermostat, which is another name for a "water choke" is stuck and the gasket blew because the water is getting too hot....?
And I have to say, you really need to place some "punctuation" in your post. Your entire post is one long, "run on" sentence and for me at least, it was really hard to read and understand.
I bet if you put in a couple periods, a few capital letters to start a sentence, you might get a few more replies.
