PCV Automobile Restoration

Almost all positive crankcase aeration structures have a regulator identified as the PCV valve. When does the PCV regulator need to be changed? Read more so you can find out for yourself.

When Should You Replace the PCV Valve?

The PCV system is seldom listed as a maintenance item, but an old valve that is no longer functioning like it should can cause performance and emissions problems. A PCV valve that’s supposed to regulate the flow of these gases is the heart of most PCV systems (some newer vehicles don’t have a PCV valve). The PCV valve routes air and fuel from the crankcase back through the intake manifold to the cylinders rather than allowing them to escape into the atmosphere. If the valve doesn’t open and close on schedule, or if any part of the system clogs, the result can be a rough idle, sluggish acceleration or increased oil consumption. Rough idling is commonly caused by bad spark plugs, so problems with the PCV valve are often misdiagnosed. If you have a bad PCV valve, PCV valve replacement could eliminate the problems listed above.

If you overhear a hissing noise from the engine, it is time to get your automobile checked at. The PCV valve pipe may have seepage in it, which is producing the hissing noise. Leaving this for a prolonged period can result to backfires; bumpy running, vacuum seepages and you will have a more widespread restoration on your hands.

Symptoms of a Bad or Failing PCV Valve Hose

The Positive Crankcase Ventilation (PCV) valve hose transfers excess gasses from the crankcase to the PCV valve. From there, it is added to the intake manifold and used by the engine. If the PCV valve hose breaks, the gas will not be transferred back into the engine, and your vehicle will be less efficient and have increased emissions. There are a few symptoms to watch out for when you have a bad or failing PCV valve hose.
1. Poor fuel economy

If the PCV valve hose is clogged or has a leak, it may cause poor fuel economy. This is because the vacuum on the intake side of the cylinder head will not be able to properly signal the correct amount of fuel that needs to be fed into the engine and can result in a lean or rich engine condition. If you suspect a PCV valve hose is the reason you have been getting poor fuel economy, contact the professionals at YourMechanic to have your PCV valve hose replaced.

Though it’s not registered in the repairs timetable in most means of transportation, the PCV structure must be reviewed occasionally to make certain it’s still in worthy state, particularly if engine performance has declined. And for your body repair needs we at Guanella will take care of it for you.
