If engine oil ends up in the radiator, it usually is due to a cracked head or blown head gasket. If the crack is adjacent to the oil pump, the resultant pressure can blow either the radiator or a cooling hose.Know More
To fix an oil problem in the radiator, first pull off the cylinder head and review it. If the issue is a bad head gasket, the part needs to be replaced, according to the Car Talk website. If the head does not feature any cracks, the next place to look is the block.
According to Eric the Car Guy, a blown head gasket denotes that the combustion system is leaking oil into the cooling chamber of the car. Head gasket failure is often the most frequent reason for such a leak. Another possibility is that a leaking intake gasket is causing an oil problem.
Eric the Car Guy notes that seeing white smoke coming out of the tail pipe when the temperature is at least 50 degrees Fahrenheit is a strong indicator that a combustion leak is affecting the car's cooling system. A leak-down test can determine whether a combustion leak is a problem. To conduct the test, direct compressed air into the cylinder. Look for leaks. Bubbles featured in a radiator after the pressurization of a cylinder can also be proof of a combustion leak.Learn more about Car Parts & Maintenance
Soaking up excess oil, emulsifying the remainder and then using solvents when appropriate combine to make the best cleaning solution for engine oil. Time is of the essence to ensure that as much of the oil is cleaned up as possible.Full Answer >
A gas odor in engine oil is caused by contamination of the engine oil by gas, usually due to a leaking fuel line or malfunctioning fuel injectors. However, it is normal for a small amount of gas to get into the engine oil during normal engine operation.Full Answer >
A defective radiator cap can cause an engine to overheat because the faulty part reduces the functional efficiency of the radiator. The coolant-system temperature is lowered in the radiator by passing through a series of fins and tubes, so anything that disrupts this process decreases cooling, which can lead to an increase in engine temperature.Full Answer >
Small amounts of water will likely burn off as the engine heats, but larger amounts of water will change the car engine oil's consistency, potentially causing serious operational problems with the car. Water should never be added to automotive engine oil deliberately, and typically the two substances only mix through condensation, which is normal and unlikely to cause problems. However, water can also enter a car's engine oil through broken gaskets within the car's cooling system, which would need to be evaluated by a qualified mechanic for repairs.Full Answer >
