Water and oil do not mix. Finding water in engine oil indicates a serious problem that can result in a disabled vehicle. Check the engine immediately for damage when water is found in the oil.
A blown or damaged head gasket can cause water to get into the oil system. Remove the heads of the engine to check the gaskets. Use a small flat metal scraper to remove any old gasket adhesive from the engine block and head before replacing the gasket and reinstalling the head.
If the head gaskets are not damaged or blown, take the heads to an automotive machine shop where they can be checked for cracks or other damage. Replace the heads when cracks are found.
A cracked engine block is the most serious issue. If the head gaskets or heads have no damage or cracks, the entire engine block must be removed and stripped down the core and taken to an automotive machine shop to be checked for cracks or damage. Replace the engine block when cracks or damage is found.
