Engine issues are never fun. There’s a number of potential reasons your compression is low—you’ll need to find and replace whatever part is causing your issue. Luckily, if you determine it a mechanic should be able to fix a low compression easily—or you can give it a go if you are handy!
Compression happens when air and gas mix in the engine’s cylinders. Without compression, the car could not move. So, if your car has low compression, it will have trouble moving. While there is no one obvious reason for compression issues, here’s a few potential issues:
*Holes in a piston.
*Leaky valves.
*Blown head gasket
*Damaged piston rings.
Open the hood and check on these individual components—it’s likely that one or more of these parts will be damaged. Once you identify the problem part, you’ll want to have it replaced.
If this is all sounding a little too hands-on, you’ll want to take your car to a mechanic!
