How to know when to replace a PCV valve?
One of the most obvious warning signs your PCV valve may need replacing is smoke coming out of the tailpipe or excessive oil consumption. If the PCV valve is stuck in the open position, it will draw excess vapors from the crankcase and burn more oil than expected.
When to change PCV valve honda civic?
PCV valves are recommended from 35,000 -60,000 miles, with most being right at the 50,000 mile mark. Many turbocharged engines require more frequent changes, and may have a secondary PCV valve in the PCV system.

How can I tell if my Honda Civic has a vacuum leak?
The easy way to find out if there is a vacuum leak is to spray the hoses with starter fluid or brake cleaner. Make sure this is done on a cool engine. If any of the hoses are cracked or not sealed correctly, they’ll suck in the vapor and the car’s idle will change. This should help you find the general location of a leak.
What causes a lumpy idle on a Honda Civic?
A failing IACV will result in a hunting idle (where the revs go up and down without accelerator input) or a lumpy idle (where the idle will fall until the ECU compensates and rises it again repeatedly). To fix this, either replace the IACV or clean it. Figure 2. Idle air control valve
How does a PCV valve work on a Honda Civic?
Although small, it performs the necessary task of removing combustion gases from the crankcase and sending them through the intake manifold to be burned again. This reduces the pressure within the engine’s crankcase, as well as helping to reduce emissions by recirculating the combustion gases back into the engine and burning them a second time.

How does the PCV valve in a BMW work?
The PCV Valve transfers gasses from inside the crankcase to the intake manifold where they are burned as part of the normal combustion process. Excess fumes are burned by the engine, rather than released into the atmosphere.
