I did have problems finding parts, but I found Auto Zone seems to be pretty good at finding them. Schucks was worthless, and NAPA was good for glow plugs.

My 4D55 is running real good after my rebuild, but I don't think I honed the cylinders enough. I still have some smoke after 1500 miles. Might take a little longer to break in, I guess <img src="/forums/images/graemlins/lol.gif" alt="" />

I still have some wiring issues to work through, and the truck is still kind of rough, but it does run real nice, and I get close to 30MPG with mixed driving. Not bad for a truck almost 25 years old and over 265,000 miles!
