Your cylinder head is a critical part of your diesel engine. Along with the head gasket, it creates the combustion chamber that allows the combustion process to occur properly. It also lets air in and exhaust out. Coolant and fuel both flow through your cylinder head. This makes its health vitally important to proper engine function. You might notice several key symptoms of cylinder head problems, including high oil consumption, bad fuel mileage, and engine overheating.

Signs of bad cylinder head

Every engine is due for repairs from time to time. Among the most important pieces of most engines is the cylinder head, which, if damaged, can prove increasingly perilous the longer it goes unrepaired. Here are some warning signs and symptoms which may be caused by cylinder head damage. This can be seen in lower gas mileage, sluggish acceleration, and difficulty getting up steep inclines. The Verdict : This is most often among the first signs of a cracked cylinder head, and usually can be repaired if caught in its early stage. A cracked cylinder head can cause this to leak, which can be most noticed by a puddle of oil forming on the ground when the vehicle is parked for a long enough time. The Verdict : Usually, unless oil has backed up into the engine and caused any damage to other parts, a leaking cylinder head can still be repaired and may not require replacement. Coolant is responsible for cooling the engine, cylinder head, and many other processes. Similarly to oil, a cracked cylinder head can cause coolant to leak. Coolant can potentially contaminate the oil, and therefore the cylinder head should be repaired as soon as possible. The Verdict : Unless the coolant has contaminated the oil due to a large enough crack in the cylinder head, at this stage the head can usually be repaired, not replaced. A cracked cylinder head may be unable to create the required atmosphere for proper combustion within those cylinders, leading to failures to combust, or engine misfires. The engine may die repeatedly during use, or fail to start at all. The Verdict : This is a more severe sign, and usually is indicative of serious damage.

When damaged, the engine risks overheating and losing power, among other issues.

Cylinder head problems affect engine performance. If not attended to on time, the problems lead to engine issues and eventual damage.

The internal combustion engine is made up of many parts that ensure its proper functioning, but various defects can occur that can weaken its power and can even lead to total failure. One of these problems can be a cylinder, or more, that no longer works at all, and because of this, the driver will feel a significant engine power loss. If we take as an example a 4-cylinder engine, the combustion will occur only in three cylinders making the engine lose a quarter of its power. One of the most common causes. If there is a spark in other cylinders, the wire to this cylinder is shorted. You can install a spare and check the spark on this particular wire. Other reasons may be a damaged spark plug, or one ignition distributor contact may be broken.
