Description
COMMON CYLINDER HEAD FAILURE SYMPTOMS
OVERHEATING
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
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.
