We had finally a nice warm day on a weekend, so I started to undo the winterization process. Noted that I'm getting a pretty consistent drip of water from what appears to be the back side of the circulating pump. Not a drip from anywhere else.
I can't see the source, but its not from the front, and its not leaking from the passages back into the block, that I can see.
There is no external rust that I can see, it seems that it must be the gasket on the back of the water pump.
Is this a common failure point?
I'm trying to figure out if it was caused by a mistake on my part for the winterization steps. I'm guessing that maybe some water sat in there over the winter. The block was drained, all the hoses were disconnected (at the bottoms), and the manifolds/risers. But, I'm not sure if it is possible for water to sit in the pump after all of that.
From the OEM manuals it indicates that there is no repair of the pump itself, but are the gaskets on the back plate available?
