We get it. When something goes wrong in your diesel engine, you want to get it fixed and get back on the road right away. Sometimes it’s tempting to do the quickest or least expensive fix just to get going again.
Within your diesel engine, there are many different components that can fail or cause you problems, including your connecting rods. It’s important that when you’re working on your engine, you replace all affected parts, otherwise you’re likely to have more problems down the road. When you’re paying for a repair, you want to make sure it’s done thoroughly, otherwise you’ll just end up paying for it again. That’s why proper diagnosis is so important.
In this failure analysis, you’ll see what happens when not everything is updated in an overhaul.
