The Engine Runs!!!
Hey!
I ran the engine today and it has good oil pressure.
My water pump leaks (which is the one that was on it from dissasembly). It did not leak before I took the engine apart.
I guess I need to get a new or rebuilt one.

That's good news on the engine Ryan! I'm hoping for similar success after several engine-related Winter projects here. As for the water pump... I guess that just follows Murphy's Second Law: Every solution results in a new problem. Oh well, you'll make quick work of it I'm sure. 
Support our troops, past and present.

Water Pump
Ryan,
There is someone on Ebay selling NOS water pump impellers regularly.

Ryan, I rebuilt mine… it was not really hard to do… Please understand I did this in an attempt to save a few dollars and was successful. It could have as easily gone the other way...
I had to do this as I was unable to get the shaft out of my housing as per the manual (there is a section on rebuilding the water pump there) if you can get the shaft out just use a press and it will go a lot easier… maybe someday I can get one…
I bought the parts from A&P Trucks here in OKC. He sells on eBay quite a bit… He has a water pump on ebay right now for about $60...
After I got the kit, which included impeller, fiber gasket and a spring and gasket to put the pump back on with (Not sure of all the parts)
I used a drill press to drill from the rear of the water pump into the impeller beside the shaft… do not damage the shaft. (a hydraulic press will also work) (I used a drill press as I wanted a straight shot beside the shaft)
I then took a chisel and forced the impeller to crack at the point I drilled it out. I then removed the impeller and fiber gasket and spring. Replaced them, using a board and a brass hammer to drive the impeller back onto the shaft, I used plenty of white lithium grease to aid in this. A hydraulic press would be ideal for this stage… with luck it will go easily…
I hope this helps and it goes well for you…
Call me if you need to…
