Preparing the engine for re-assembly.
Most people neglect or even flat out forget to give the engine block a pressurerized oil,air and water treatment before re-assembling it.But it is a must especially if the engine has been idle for a long time.Remember I'm talking about the block only,remove the Crank shaft along with the con rods,liners(if applicable) and pistons.Your local service station should be able to handle it.
1.Pressure wash the block with a 1/2 litre of penetrating oil.Have them concentrate on the insides and the water/oil lines around the block.
2.Wait about 10 minutes then pressure wash with 1 litre of diesel,
3.Air it out with highly compressed air,again concentrating on the water and oil lines surrounding the combustion chamber
4.Pressure wash with water.
5.And finally.finish it off with a litre of petrol.applied same as above.
