Can anyone help me with a question? I am going to buy a wd allis....the man says it has a cracked block (water in oil) Is this fixable? or will a new block be needed? What would you do first to check the engine over to see how serious? Maybe it is not as serious as he thinks? Thanks
Victor

Victor; Water in the oil can be from various causes. Cracked head, cracked sleeve, bad sleeve seal, blown head gasket or a cracked block. To get a handle on the cause, do a cylinder leak test. us an air compressor and pressurize each cylinder to around 30 psi. Watch for bubbles in the radiator. Be sure radiator cap is off to aviod splitting radiator tanks. Cylinders should hold pressure or bleed down very slowly. Rapid pressure lose from any cylinder would indicate a problem, like a cracked sleeve, or head. Then do a cooling system pressure test. pressurize radiator to about six psi. It should hold pressure and not bleed off. If pressure starts dropping and there are no external water leaks, this suggests an internal leak. Again this could be a cracked head or block, blown head gasket, or a bad seal ring on one or more sleeves. It helps to have the oil pan off for this, as it makes it possible to see where the water comes from. In the event the block is cracked, they can usually be repaired. Hope this helps you.
