" Alan,

If water is getting


" Alan,

If water is getting into #3, you should see a heavy, muddy deposit on the spark plug.

Usually, the water would be getting in through the exhaust ports. It could be due to a worn gasket on the exhaust cover or plate, or a badly corroded surface on either of these two parts, or on the block itself.

This assembly is on the port side of the block.
