1951 Dodge farm truck - Inside the free, donor engine

[Bobacuda]

Pulled the oil pan…yuck. About 3/4” of emulsified goo. The oil pump intake was submerged in it. Lots of cleanup required. 
 

Since the engine is “upside down, I pulled a rod cap. Some very light marks on crank - could not feel/scratch them with my fingernail.  Pulled the inner two main caps.  Once again, no scarring. 
 

Overall, the bearings need changing. And they are marked 020 on their backsides. I lubed and retorqued it all back. 
 

Next, I opened up the front end to check on the timing gears and chain. There is about 3/4 to a full inch of slack in the chain. Definitely going to be replaced. The big surprise for me was on the timing gears!  They are Mother Mopar originals - stamped DPCD. Kind of hard to see in the photo. 

Time to start searching for parts.

This should be good for a laugh. The drain plug has been out for years, but the oil-muck was gooey enough to stay in.
 

As you look At the crap the bottom of the pan, you can see where the sump was submerged.  The sump is also pretty gummed up.  Now, cosider the engine was upside down when I removed the pan.

Lost is the Polaroid that captured the softball sized ball of goo that I removed from the oilpan of the '49 that had been parked in The Panhandle/w.OK region for 20yrs...ended up patching a driveway pothole with that gritty gunk.
