While not all blown head gaskets progress to this point before being noticed, some cases do. The second sign is oil in the antifreeze. If carbon is present in your antifreeze, most likely, the problem is with the head gasket rather than a crack in the engine block or cylinder head. Many brands are available but look for one that allows you to put a few drops of antifreeze in the solution to check for carbon. The good news is since your oil is not contaminated with coolant, there should be no actual engine damage provided you replace the head gaskets soon. There are three sources that cause coolant in the oil. As a result, when the head gasket fails, oil can make its way into the coolant system. Coolant in the crankcase don't usually come from a failed water pump. The first sign is the evident through the use of a chemical test solution. I cannot believe any dealer would replace a water pump without first doing a compression test and a leak down on the cooling system. These problems can be difficult to track down and expensive to repair.īelow, I outline four signs of a blown head gasket. ![]() Unfortunately, water in the oil can also be a symptom of a far more serious problem, such as a cracked engine block, a cracked cylinder head, or a leaky sleeve. ![]() While you have to tear the tractor down to the engine block to make this repair, the fix is straightforward and relatively inexpensive.
