In some cases, the damage can be severe enough to require the engine to be completely replaced.

How to Detect it?

• It’s possible that the fuel filter is clogged, which would prevent fuel from getting to the engine.
• In addition to this, the exhaust pipe may be emitting a significant amount of white smoke.
• At some point, the engine will become completely powerless, and you will no longer be able to start it.
