Diesel Diagnosis: 9 Telltale Signs of Diesel Engine Cylinder Head Failure

In this video, Highway and Heavy Parts Sales Technician Rob breaks down all the possible signs that your old diesel engine cylinder head needs replacing and how to prevent catastrophic failure.

The cylinder head is one of the most critical parts of your engine. It allows air intake in, and the exhaust out. Coolant flows through your cylinder head, and so does fuel a lot of the time. So you can see there are lots of opportunities for failure.

Diesel Cylinder Head failure symptoms usually include:

High Oil Consumption
Bad Fuel Economy
Overheating (Leading to Cracks)
Worn Valve Stems and Valve Guides
Oil Leaking into Combustion Chamber
Valves Not Sealing
Cracks Through the Fuel System
Cracks into the Cooling System
Coolant in Engine Oil
