Build Rebuilding Toyota Engines

Engine block cleaning.

1 Clean visible surfaces using your favorite method. DO NOT USE POWER/AIR TOOLS ON PRECISION/GASKET SURFACES! I use soap, water, old toothbrushes, and lint free rags.
2 Pull the freeze plugs and clean out the coolant galley.
3 Remove gunk from the oil feed passages. Particulate trashes rotating assemblies!
4 Dry the engine block ASAP. Use a suitable surface protectant(s) to prevent rust. Rust destroys precision surfaces.
5 Place your engine block in a clean plastic bag.
I clean engine blocks after they come back from the machine shop, even if they already cleaned it.

Step 3: A stack of solidified filler metal puddles was used to remove the oil galley plugs.

A brush with patches was used to clean the right and left side 2JZ-GTE oil galleys. First patches on top and last two patches on the bottom.

Grit was removed that could be felt between fingers. Particulate trashes bearings, journals, turbos, and plugs oil squirters.
