The water pump housing that connects to the block is the place were my gasket is blown. Taken all bolts out, and the only thing holding it on is a one inch bolt on a disc at the bottom of the housing that goes to the timing chains. Should I take it off or not?

 

sure why not?

 

be careful to see how everything is lined up prior to pulling things off...
