Cleaning cylinder head

Using a wire brush and PJ1 cleaner carefully remove any carbon deposits from cylinder head.

Cleaning cylinders


Clean the cylinders with a brush and cleaning solvent. If aluminium deposits are present first heat the cylinders then apply a small quantity of muriatic acid with a brush, let stand for several minutes then clean thoroughly with solvent.

Once the aluminium deposits have been removed from the cylinder wall, hone the cylinders first from one end then the other. When finished the cylinders should have a distinct cross hatching pattern on the cylinder walls.

Using a wire brush remove all carbon deposits from exhaust ports. If present remove cylinder base gaskets, exhaust gaskets, and intake manifold gasket material. Rinse cylinders thoroughly in cleaning solvent, and then using a oil soaked rag wipe inside the cylinder walls, until walls are coated in a thin layer of oil.

Cleaning Pistons


Before cleaning the pistons carefully remove the rings. Then using a wire brush and cleaning solvent remove the carbon deposits from the top of the pistons, and from within the ring land area.

If replacing rings, use old ring to scrape any remaining carbon free from the ring seating area. If you are reusing old rings ensure they are replaced on the same piston and installed in same cylinder.

Caution:

Be careful not to damage the ring lands, piston dome or skirt area.
