Engine troubles are never pleasant to deal with, especially if you're told that your engine is blown. This can signify a number of different issues but typically means there has been a major failure within the engine that will require either a full-on replacement or some rebuilding. You could have a blown bottom end or a blown head gasket, which are the most common issues when referring to a blown engine. Can either of these problems be fixed, and are they worth fixing?
First, let's understand what a blown bottom end is within the engine. This occurs when the rotating assembly fails under really high RPM and actual broken-off parts from the assembly damage the engine block. If the damage is extensive, the engine block often can't be repaired and will need to be replaced.
Another engine problem that is often referred to as a blown engine to some is a timing belt snap or timing chain break. When this happens, it can cause severe damage to your engine's valves and pistons. This can cause piston parts to get into the oil pan which can damage internal engine components. In this case, a replacement is usually recommended because the repairs can be too extensive. This is why it is so important to have your vehicle's timing belt or timing chain replacement according to manufacturer recommendations before it breaks.
A blown head gasket is also a major engine issue, and it can fail in a number of different ways. Its main job is to help keep in combustion pressure and prevent oil and coolant from mixing. If it fails, typically coolant or oil can be mixed or start to leak, which can quickly lead to engine overheating and combustion problems. The head gasket can be replaced, but the engine will need to also be assessed to determine how much damage was caused. Other repairs may be needed in addition to the head gasket to restore what was damaged when the head gasket failed.
These are just some of the main issues that a blown engine can refer to, however, more broadly the term just represents an overall failing engine. If you do have a blown engine, whether or not it can be fixed depends upon the extensiveness of the damage. If the damage is minimal, and a few parts can be replaced, the problem can be fixed. However, if the damage is great and impossible to repair, you may need a complete engine replacement.
