COMMON CYLINDER HEAD FAILURE SYMPTOMS
Cylinder head cracking is a quite common problem in diesel engines that can lead to other issues. Excessive heat causes the head to expand and contract, which leads to cracking. Depending on the model, the head is sometimes made of a different material, which can make this problem worse.
A crack in your diesel engine's cylinder head could go through to your coolant passages, which allows compression gases from the combustion cycle to fill those coolant passages. This displaces the coolant, which causes the head to overheat in certain areas. This overheating tends to crack the head worse.
If you find that your diesel engine cylinder head has cracks between the valves, read our blog to learn what you can do about cracking.
POOR FUEL ECONOMY
A decrease in your diesel engine's fuel economy could be caused by valves that aren't sealing and creating the right pressure in the combustion cycle. In this case, you'd be putting significantly more fuel in the engine to get the same amount of power.

EXCESSIVE OIL CONSUMPTION
Sometimes the valves and valve guides will wear, or seals will come off or get dislodged (knocked or forced out of position), allowing oil to enter the intake or exhaust ports, which causes high oil consumption.
Read our blog to learn more detailed information about excessive oil consumption.
White smoke can also be an indicator of cylinder head problems. In extreme situations, white smoke can come from the diesel engine itself, indicating that coolant has contaminated your oil due to a cracked or damaged head. It could also indicate exhaust gases escaping through the cylinder head, which signals the need to replace it.
It's important not to ignore these warning signs. While these symptoms might indicate issues other than your cylinder head, don't assume it's not your head. Be sure to evaluate the health of your head to try and prevent catastrophic engine failure from costing you even more time and money.
