Engine Inspection
With a bright light I've looked at what I can see of the pistons, rods, crank. Everything seems clean enough, but otherwise the components have a gummy, tacky feel.
The oil pan gasket was neither gasket nor permatex, but some sort of dark nearly black hardened material like gasket maker that intruded into the sump area. A small amount of particles at the bottom of the pan were not magnetic. The pump screen had a piece of the material there too.
Probing some of the oil ports a small chunk fell out. This was enough to significantly reduce oil through that passage and concerns me.
After sitting so long, I was expecting rust, but the cylinder walls are shiny, and I see uniform scratching that appear to be cross-hatching from a rebuild.
Should I be too concerned about the particles? Blow the bottom end out with air or flush with engine cleaner?
I am replacing the oil pump with a Melling standard flow after the local rebuilder suggested I at least clean the old one thoroughly. After taking it out it turned with resistance too.

If you are going to pull the pan or already have it off might inspect the bearings for discoloration or grooves could even plastigauge it just for piece of mind. Might be ahead to toss in new bearings if you have any concers on the bottom end before you button it up.

Yeah, the freshly scrubbed and very blue oil pan is sitting in my back yard awaiting its return to the engine. I have the engine lifted with transmission attached ready to go in the truck except core plugs and oil pan.
I was wondering how to go about cleaning the oil journals, blow it out with air? I've got a siphon nozzle can send a solvent in passage ways but don't know what felpro means by cleaning though it makes sense to do it now.
I'm not sure how much more I'll do until I find out whether it has cracking in the lifter valley... just verified it falls in the suspect year range for 400 blocks... it's a '76.
