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.

When Should I Get a Diesel Engine Rebuild?

A rebuilt diesel engine can last for an extended period, providing reliable performance. Typically, diesel engine rebuilds become essential around the 750,000 to 900,000-mile mark. However, factors such as usage in various applications, general maintenance, driving habits, and more, can necessitate a rebuild sooner.
