Do You Need a Compression Test?


Do You Need a Compression Test?

Your car’s engine compression can tell you a lot about the overall health of the engine. If your car is blowing blue smoke out of the tailpipe, or if your car is losing lots of oil, you could have a bad piston ring. This will also cause low compression in that cylinder, and a compression test will tell you. The same goes for a bad valve. Even if you are just noticing a general lack of power, a compression test can help you rule out some of the more serious possible causes.
