How Do You Know if a Diesel Engine Is Blown?
A blown diesel engine may exhibit signs like excessive smoke with a blue or gray tint, loss of power during acceleration, knocking sounds, persistent overheating, and contaminated engine oil with a milky appearance. Additionally, visible damage, failure to start, abnormal exhaust pressure, and unusual smells such as burning oil or coolant are indicators.
How Can I Avoid Engine Repairs?
To avoid engine repairs in heavy-duty diesel vehicles, follow a strict maintenance schedule, regularly change oil and filters, monitor coolant levels, use quality fuel, and address warning signs early. Preventive maintenance and timely diagnostics help extend engine life and reduce costly repairs.
