When to Run a Compression Test for your Car | Roberts Automotive and Industrial Parts Manufacturing Corporation

An engine is a “self-powered air pump”, and its quality is one of the determining factors in the overall performance of every vehicle. Because many of its components are complex, such as the cylinders, piston rings, and pistons, a busted engine would usually require the expertise of a trusted and competent automotive shop. This is one of those times where a knowledgeable driver would consider a compression test, but how can one be sure on when exactly to run such a test? Below I have listed a few symptoms that would indicate the need for you to run a compression test for your car.

Indications of a bad exhaust valve include misfiring at low engine speed, no compression on cylinders, irregular exhaustion of black smoke from the exhaust pipe, excessive oil consumption, compression leaks, valve train noise, and total valve failure.  If you experience any of the malfunctions, consider running a compression test for your car as soon as possible; ignoring these problems could lead to worse engine damage. Once the compression test is finished, overhaul the cylinders (if there are any) as exhaust valves play an important role in the car’s engine system.  Every driver should consider the possibility of a faulty exhaust valve after every compression test.
