Last push before paint

Pulled the water pump – eewww… nasty. Also popped the oil pump cap off and cleaned out what I could behind it. The aftermarket mechanical oil pressure sending unit is now in the bin as well – gotta find the right fitting to put a proper electric oil pressure sender back on. Also got the rest of the main body of the block cleaned up with a conical wire brush… that little die grinder really blows through the air in the compressor – seems like it ran non-stop once I started using it. Also dropped all of the bolts for the oil pan and water pump in a jar of Simple Green to soak. Hopefully, that’ll clean them up.

Tomorrow, install the new water pump and oil pan, tape off a few things, and paint this sucker.

Yeesh! That’s the crud that was hiding in the water pump, and not very inspiring. It didn’t seem to go any further into the block, so hopefully just running some anti-freeze flush when I get it running will clean out any leftovers.
The die grinder and conical wire wheel made quick work of the icky water pump residue. That shiny spot was about the only bad spot that corroded. Fortunately, it’s in a spot with lots of material behind it, so no blow-thru to be expected.
Almost done with the wire brush. Getting close!
Taped off the oil pump, and hit this side with the wire brush one last time. Ready for paint!
One last shot after finishing up with the wire brush. Ready for paint! Keeping my Jeep in gray scale, I’d actually thought of painting it black, but changed my mind to go with Duplicolor Cast Iron, since I’ll paint the pulleys and accessories gloss black, and have a bunch of chrome goodies to go with it all.
