Bobacuda Posted May 19 Report Share Posted May 19 (edited) Moved the free engine for the ‘51 farm truck out of the shop to scrape, steel brush, degrease and pressure wash it. I think I removed enough crap to fill a 2 lb coffee can. I also removed the 5 freeze plugs - wow. The crud totally covered the 2 lower plugs - rust, calcium carbonate, and Stop Leak. On top of that, during the replacement of one of the lower plugs (photo attached) the mechanic knocked the old plug in the water jacket and left it. That one was a challenge to de-crud and get the ancient plug out. I dug a lot of crap out by hammering a screwdriver into it. Then I used the pressure washer. Took over an hour to finally get clear water with no chunks. Edited May 19 by Bobacuda 2 Quote Link to comment Share on other sites More sharing options...
Ivan_B Posted May 19 Report Share Posted May 19 Did you manage to get the distribution tube out? If you have the engine removed, etc., I would probably take it to a shop to have it properly hot soaked. Also, was your block drain still working, with all that debris behind the plugs? My block drained just fine, but I never took the plugs out 🤔 Quote Link to comment Share on other sites More sharing options...
Bobacuda Posted May 19 Author Report Share Posted May 19 Ivan - The engine had not been in a truck or in use for at least 3 years. It is from a truck that was in a boneyard that was bought just for the body. The engine (longblock) was stored in a garage. It only took about 1.5 hrs to get the water distribution tube out, and it wasn’t rotted. I have other stuff to do before I will have time to pull the head and oil pan to assess the engine’s internals. If it all looks rebuildable, then it’s machine shop time. BTW, looking for brass concave freeze plugs to replace the steel ones. Everywhere I check says “not available.” Anyone have a good source,?

Bobacuda Posted May 19 Author Report Share Posted May 19 Found the 1 5/8 freeze plugs (Melling 14B) in stock on Rock Auto 😁 Quote Link to comment Share on other sites More sharing options...
Bobacuda Posted May 22 Author Report Share Posted May 22 (edited) Had time to pull the head today. Black soot, not greasy. Thinking it was run very rich before it went to the boneyard. One stuck valve, freed it up with PB Blaster. Cyl walls could use a dingle-ball hone. Slight ridge at top of cyinder. Pistons are stamped “060” when read from the valve side. Need to pull oil pan and see what the lower end looks like. Edited May 22 by Bobacuda 2 Quote Link to comment Share on other sites More sharing options...
