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
