Cleaning Out Bearing Debris

[SpeedThrills]

I'm cleaning the inside of my 360 thoroughly, because a rod bearing spun and put metal through the engine.

I did this once before about 30 years ago because of a wiped cam. (I've also done it to freshly machined blocks, crank, rods, etc.)

I can't remember what we did about the (hydraulic, in this case, too) lifters. I don't ever remember disassembling lifters, let alone doing it to clean them.

Do lifters get metal in them?

Yes they do. Get cases of brake clean a bunch of different size pipe brushes and High pressure long tube blow gun. Then after all of that another soap and water bath with the same but new brushes. Getting it cooked may be a good idea if you can get it to a shop. That metal Gets in the galleys and is stubborn to get out. Its like splinters in the coarse cast iron.

Eight down, eight to go. They're easy to disassemble.
Turkey time!

They're all done. I'm glad I cleaned them. The picture (sorry, it's poor), shows material on the tip of the magnet that I ran through the fresh gas that I cleaned them in. I replaced the gas every 4 lifters. Air hosed them. (Ignore the white spot, I believe that's a reflection from the bench light.) It's almost powdery.

I should've included the words, "and crankshaft journal" in the thread title. The crank has a step that's about .005-.007", on the side of the journal that's closest to the crank C/L, for lack of a better way to to describe it. Any way, that metal, along with the bearing material, had to go somewhere.

Everything else will be getting a thorough bath as I go through this thing.

The lifters have been "bagged and tagged" with their corresponding bore location.
