Another vulnerable component is the intake manifold gasket, which often seals the coolant passages for the cylinder heads; a leak here allows coolant to enter the oil before it even reaches the combustion chamber. This combination typically indicates a serious internal failure, where coolant has found its way into the combustion chamber or the engine oil passages.
Dangers of Ignoring Coolant Mixing with Engine Oil
This emulsification is the direct result of coolant mixing with the oil. Its job is to seal the combustion chambers and the internal coolant and oil passages.
In many cases, the head must be removed to inspect for warping or cracking. The most visual sign is the appearance of a thick, milky, mayonnaise-like substance on the oil filler cap or on the dipstick.
Recognizing the Serious Risks of Ignoring Oil and Water Mixing in Engine Oil
Engine misfires or a significant drop in performance due to combustion byproducts entering the oil system. A compression test or a leak-down test can help determine if a head gasket is blown by measuring pressure loss in the cylinders.
