Certainly not a good thing to find anti-freeze in the oil. Some possible sources include: Leaking liner seals Head gasket Corroded block in the top and leaking seals and hoses allowing the coolant to get into the crankcase. You definately need to find the source of the leak. Anti-freeze is not a good lubricant and will ruin your bearings, cam, cylinder walls, and pistons. A presssure test on the coolant system should help you find the leak. You may need to remove the intake manifold to examine all possible sources. Has your engine ever been overheated?
