What are the Symptoms of a Bad Turbo in the Isx Cummins?

When it comes to diagnosing a bad turbo in an ISX Cummins engine, there are several symptoms that can give you clues as to what is wrong. One of the first signs of a bad turbo is increased black smoke from the exhaust. This indicates that too much fuel has been injected into your engine and not enough air is being drawn in by the turbo.

You may also notice a decrease in power output or hear unusual noises coming from the turbo itself. Other symptoms include excessive oil consumption, poor idle quality, harder starting than usual, misfiring under load, high EGTs (exhaust gas temperatures), and sluggish acceleration. If these symptoms are present in your vehicle then it’s likely time to replace your bad turbo with a new one.
