A blown head gasket in a Detroit 60 Series engine can cause a range of symptoms that can indicate a serious issue with your vehicle.
From overheating and coolant loss to oil contamination and loss of power, a blown head gasket can lead to costly repairs and even engine failure if left untreated.
In this blog post, we will explore the common symptoms of a blown head gasket in Detroit 60 Series engines and answer some frequently asked questions to help you better understand this issue.
Detroit 60 Series Blown Head Gasket Symptoms
Here are the symptoms of a blown head gasket in a Detroit 60 Series engine.
Coolant Loss and White Exhaust Smoke
A common sign of a blown head gasket in the Detroit 60 Series engine is coolant loss at the surge tank, as well as white exhaust smoke that smells sweet.
This happens when the head gasket is damaged, allowing coolant to enter the combustion chamber and be burned off.
The white smoke may be visible even in warm weather conditions, and the engine may consume a significant amount of coolant.
Loss of Power and Rough Running Engine
Another symptom of a blown head gasket in the Detroit 60 Series engine is a loss of power, as well as a rough running engine.
When a head gasket fails, it allows compressed air/fuel to escape, resulting in reduced compression in that cylinder.
This can lead to rough running, as well as a notable reduction in engine power.
Oil or Coolant Leak
An external oil or coolant leak at the seam between the engine block and cylinder head is another sign of a blown head gasket in the Detroit 60 Series engine.
This can occur due to a failure in the head gasket or a cracked block.
When disassembling the engine, it is important to check for cracks and cylinder head warping.
Bubble Formation and Milky Discoloration
When a blown head gasket occurs in the Detroit 60 Series engine, bubble formation may occur in the radiator and reservoir overflow.
The oil may also have a milky discoloration, as seen on the oil filler cap.
This is due to the coolant mixing with the oil, which can occur when the head gasket is damaged.
Combustion Leak Test
Performing a combustion leak test can also help diagnose a blown head gasket in the Detroit 60 Series engine.
If the test confirms that the engine is leaking coolant, this is a clear indication of a head gasket failure.
Common Causes of Blown Head Gaskets in Detroit 60 Series Engines
Here are the common causes of blown head gaskets in Detroit 60 Series engines.
Overheating is one of the most common causes of blown head gaskets in Detroit 60 Series engines.
When an engine overheats, the metal expands and pinches the head gasket, which can cause it to fail.
This can happen due to various reasons, such as a malfunctioning thermostat, a faulty cooling fan, or a clogged radiator.
If you notice that your engine is overheating, you should immediately address the issue to prevent damage to the head gasket.
Preignition occurs when the air/fuel mixture ignites before the spark plug fires.
This can cause the engine to knock or ping, and can also cause damage to the head gasket.
Preignition can be caused by various factors, such as a faulty ignition system, poor fuel quality, or an incorrect spark plug gap.
If you notice any unusual engine noise or poor engine performance, you should get your engine inspected for preignition issues.
Improper maintenance of the engine can also cause the head gasket to fail.
Neglecting regular oil changes, failing to replace the coolant at recommended intervals, or using the wrong type of coolant can all cause damage to the head gasket.
It is important to follow the manufacturer’s recommended maintenance schedule to prevent premature failure of the head gasket.
Wear and Tear
Wear and Tear As with any engine component, the head gasket can simply wear out over time.
This is particularly true in high-mileage engines or engines that have been subjected to harsh operating conditions.
When the head gasket wears out, it can no longer seal the combustion chamber properly, which can cause engine damage.
In some cases, manufacturing defects can cause the head gasket to fail prematurely.
This is rare, but it can happen. If you suspect that your engine has a manufacturing defect, you should contact the manufacturer or a qualified mechanic for inspection and repair.
How to Test for a Blown Head Gasket in a Detroit 60 Series Engine
Here are some ways to test for a blown head gasket in this type of engine:
Check the Engine Oil
One of the easiest and most effective ways to test for a blown head gasket in a Detroit 60 Series engine is to check the engine oil.
You can do this by pulling the dipstick and checking for any signs of coolant contamination.
If the oil appears milky or has a white or creamy color, it could indicate a blown head gasket.
Check for Coolant Leaks
If you suspect a blown head gasket in your Detroit 60 Series engine, check for coolant leaks around the engine.
Look for any visible signs of coolant leaking from the engine block, hoses, or water pump.
You can also check the coolant reservoir to see if the coolant level has dropped significantly.
Do a Combustion Leak Test
Another way to test for a blown head gasket in a Detroit 60 Series engine is to do a combustion leak test.
This involves using a special tool to detect any combustion gases in the cooling system.
If combustion gases are present in the cooling system, it could indicate a blown head gasket.
Coffee Color Test
The coffee color test is another way to check for a blown head gasket.
This involves removing the oil filler cap and checking if a coffee-colored liquid has formed in and around the cap.
If there is a coffee-colored liquid, it means that the coolant has mixed with the oil, indicating a blown head gasket.
Use a Hand Pump
You can also use a hand pump to test for a blown head gasket in a Detroit 60 Series engine.
The hand pump is attached to the radiator cap and pressurizes the cooling system.
If the pressure drops, it could indicate a blown head gasket or another type of leak in the system.
How to Prevent Blown Head Gaskets in Detroit 60 Series Engines?
Here are various ways to prevent blown head gaskets in Detroit 60 Series engines.
Maintain Proper Engine Coolant Levels
Maintaining proper engine coolant levels is critical to preventing blown head gaskets in Detroit 60 Series engines.
A low coolant level can cause the engine to overheat, which can lead to blown head gaskets.
Therefore, it is essential to check and top off the engine coolant regularly. One of the early signs of a blown head gasket is coolant loss at the surge tank.
Use High-Quality Coolant
Using high-quality coolant can help prevent blown head gaskets in Detroit 60 Series engines.
It is essential to use the coolant recommended by the engine manufacturer and to follow the recommended maintenance schedule.
Using the wrong coolant or not maintaining the proper coolant level can lead to corrosion and other problems that can cause a blown head gasket.
Check for Coolant Leaks
Checking for coolant leaks is an essential part of preventing blown head gaskets in Detroit 60 Series engines.
Coolant leaks can cause the engine to overheat and can lead to blown head gaskets.
Therefore, it is crucial to inspect the engine regularly for any signs of coolant leaks. A combustion leak test can also help identify any potential head gasket issues.
Follow Proper Torque Specifications
Proper torque specifications are critical to prevent blown head gaskets in Detroit 60 Series engines.
Over-tightening or under-tightening head bolts can cause the head gasket to fail.
Therefore, it is essential to use the correct torque wrench and follow the specified pattern and torque specifications when tightening head bolts.
Always remember the three-step rule when tightening head bolts.
Address Overheating Issues Promptly
Addressing overheating issues promptly is essential to prevent blown head gaskets in Detroit 60 Series engines.
Overheating can cause the engine to expand, which can put pressure on the head gasket and cause it to fail.
Therefore, it is crucial to address any overheating issues immediately and to identify and repair the underlying cause of the overheating problem.
