ENGINE OVERHAUL
Cylinder Block
One of the most important phases of engine
reconditioning is the thorough cleaning and inspection of the
cylinder block.
Each machined surface of the cylinder block should be
cleaned of all old gasket material. The pipe plugs which seal
the oil passages should be removed and all passages
thoroughly cleaned.
Remove the main oil gallery plug and use SE-2334-2
Brush (3/8" diameter) to clean the main oil gallery, Figure 69.
Replace oil plug after coating with a suitable nonhardening
sealing compound.
