Common Diesel Engine Issues We Fix

We regularly diagnose and repair:

• Excessive smoke (black, white, or blue exhaust)
• Hard starts or no-starts caused by injectors, glow plugs, or compression issues
• Loss of power under load from fuel, turbo, or engine faults
• Overheating due to head gasket failure, coolant leaks, or clogged coolers
• Oil or coolant leaks from gaskets, seals, or cylinder heads
• Knocking or rough running from injector imbalance or internal wear

If your engine shows these symptoms, we’ll pinpoint the cause and recommend the right repair.
