I ended up just getting another factory DME with matching EWS box and chip, so for now, I'll just use that.
Project update! (Warning! lots of pictures)
Admittedly, my progress has been pretty slow over the past few months. But I have been collecting parts as funds allow. I drained a lovely strawberry milkshake like oil mix from the transmission. Luckily, the gears inside don't show any signs of corrosion.
I then started the tearing down the engine to inspect the damage.
The camshafts looking good...
Pulled the camshafts and stored them away safely wrapped in newspaper.
This shot shows just how much silt was left on the engine.
At this point I started debating whether or not I should pull the head. In the end, I was convinced it needed to happen.
Head off!
Inspecting the cylinders and piston crowns.
Plenty of crud build-up. At this point, I'm very glad I pulled the head.
The valves have a bit of surface rust and crud on them, but I think they'll clean up nicely.
I started cleaning up the bores and tops of the pistons with some old gasoline.
I forgot to take pictures of the head when I was cleaning it, but came out equally as well as the short-block.
I then proceeded to flip the engine over, and pull the oil pan off.
Still a great deal of milky oil left coating the bottom-end.
I spent the next few weekends cleaning all of the nooks and crannies of the engine with old gas and a toothbrush.
This took far more hours than I'm willing to admit, but the end result was certainly worth it.
The engine then sat like this for a couple of months...
