[@PANTYEATR1]

I've had all of these symptoms because i used a PCV system from a 5 liter engine on my 7 liter engine. The PCV valve was working, but i think the flow was inadequate. With leak down and compression testing, i suspect broken Piston rings and lifters on 2 cylinders. 😔

[@megancarolosborne8442]

I have no trouble code, but car struggles to start but after few tries I can start it but it’s guzzling oil and fuel! Sometimes it will idle funny and cut out but majority of the time it runs fine. Also car drives perfect just when you change it takes a while to get the power from the acceleration

[@MechanicalBoost]

Struggling to start the car, excessive oil consumption, and increased fuel consumption can be indicative of several potential issues such as fuel system problems, ignition system issues, worn piston ring issues, PCV system issues or coolant leaks. Given the symptoms you've described, it's important to have a qualified mechanic perform a thorough diagnostic check to pinpoint the exact cause of the issues.

@@gavyndavis290 In my case it was the injector 3 missing it's seal and O ring. I suspect the technician who removed the intake manifold for cleaning had the injectors cleaned and missed checking the seal.

Car is misfiring. Changed spark plugs still happening. Got it checked and cylinder 3&4 air compression test was just slightly under. Would that be the pvc valve? ( I did just have the coolant system repaired two weeks ago as it was leaking )

[@MechanicalBoost]

Yes, a bad PCV valve can cause misfiring. The PCV valve helps regulate the pressure and release gases from the crankcase to be burned in the combustion chamber. A stuck-open PCV valve can allow too much air into the intake manifold, leading to a lean air/fuel mixture. Conversely, a stuck-closed PCV valve can cause a rich air/fuel mixture.

[@dangelomack1]

Can this appear as other problems like bad MAF sensors and throttle body problems? I have replaced both on my 2010 altima and still having some of these same symptom and car will go into limp mode often.

[@MechanicalBoost]

Yes, bad MAF sensors and throttle body may also have similar symptoms... You need to properly diagnose the issue before replacing any part of your vehicle.

[@RafaGudino-h7l]

Does bad pcv valve cause low oil pressure?

[@MechanicalBoost]

Yes, a malfunctioning PCV (Positive Crankcase Ventilation) valve can contribute to low oil pressure by disrupting the engine's ability to regulate crankcase pressure effectively. This can lead to oil leaks, reduced oil flow, and ultimately, lower oil pressure.

[@winsterlajara8913]

quick question, when I turned on the engine and remove the oilcap or dipstick the engine suddenly shutdown. Is this a PCV valve issue too?

[@MechanicalBoost]

Yes, it could be related to a malfunctioning PCV valve, but it may not be the sole cause. When the engine stalls after removing the oil cap or dipstick, it indicates an imbalance in the vacuum system, which could be linked to various components, including the PCV valve. I recommend inspecting the PCV valve first and checking for vacuum leaks in the system. If you're unsure, getting a mechanic to run a diagnostic would help pinpoint the exact cause.

[@tk_jackyy1437]

Could this cause an oil leak and smell in the cabin? After warm up 750 is idle speed. Is this clearly PCV damage? In the long term, what damage can be done to the engine in such a situation? tell me please

[@MechanicalBoost]

Yes, a malfunctioning Positive Crankcase Ventilation (PCV) valve can potentially contribute to an oil leak in your vehicle. The PCV valve plays a crucial role in maintaining proper crankcase ventilation and preventing the buildup of pressure inside the engine. Excessive pressure in the crankcase can force oil to leak through gaskets, seals, and other vulnerable points in the engine. Additionally, if the PCV valve is stuck in the closed position, it may cause a vacuum in the crankcase, leading to oil leaks as well. An oil leak may also cause smell in your car cabin. Over the long term, this can contribute to decreased engine performance, reduced fuel efficiency, and increased risk of costly repairs.

[@El_LeChErO91]

Ontop of oil disappearing no leaks or smoke out the back, would the inside of my car smell like exhaust when i use the ac or heater? I checked exhaust manifold and followed the exhaust system and no leaks.

[@MechanicalBoost]

Given the combination of symptoms, it is crucial to address both the oil consumption and the exhaust smell promptly. The exhaust smell inside the cabin is particularly concerning due to the potential for harmful fumes. 1) Check for Internal Oil Leaks: i) Compression Test: Perform a compression test to check for worn piston rings or cylinder walls. ii) PCV Valve: Inspect and replace the PCV valve if necessary. Inspect the Exhaust System: iii) Visual Inspection: Perform a thorough visual inspection of the exhaust manifold, gaskets, and the entire exhaust system for any signs of leaks. iv) Smoke Test: A smoke test can help identify small leaks in the exhaust system that might not be visible. 2) Examine the HVAC System: i) Inspect Blower Motor and Housing: Ensure the blower motor and its housing are free from damage and properly sealed. ii) Cabin Air Filter: Replace the cabin air filter if it’s dirty or improperly installed.

[@Justin-uv4ji]

My pcv hose got a big hole in it. Can that cause a severe oil leak after the car been running?

[@MechanicalBoost]

A big hole in the PCV hose can lead to several issues, but it is unlikely to cause a severe oil leak directly. The PCV system primarily deals with air and gas flow rather than oil. However, if there is excessive pressure buildup in the crankcase due to a malfunctioning PCV system, it can potentially cause oil leaks from other seals or gaskets in the engine. Excessive pressure can force oil past seals and gaskets, leading to leaks. If you have noticed a significant oil leak after the PCV hose developed a hole, it is possible that the increased pressure caused oil to escape from other areas. It is recommended to inspect the engine thoroughly to identify the exact source of the oil leak and repair it accordingly.

[@Justin-uv4ji]

@MechanicalBoost good news is it was just ac water dripping on an old stain on the concrete.

If your Honda Civic is burning excessive fuel even after replacing both lambda sensors, there could be several other potential causes for the issue such as air filter, fuel filter, fuel injectors, fuel lines, or fuel pressure regulators or others.

[@jogalong]

Thanks for the reply. You were right that it wasnt root cause. Aftet replacing it trims got a bit lower, but engine started reving up and down indefnitely. It could be that it wasnt airtght or smth, but even after plugging the pcv hose going to intake didnt solve high trims.

[@MechanicalBoost]

Experiencing misfiring, white smoke from the exhaust, and a sudden decrease in engine oil levels can be concerning issues, often indicating underlying problems with your vehicle. The issue may be a Leaking Head Gasket, Coolant Leak, Failed Piston Rings, Cylinder Head or Engine Block Cracks, clogged PCV valve or breather hose. It is recommended to have your vehicle inspected by a qualified mechanic as soon as possible.

Hi. I have 1.3 Toyota Corolla gli 2009 i noticed that my engine oil level decrease when i drive for long. And i seen some oil comes out through PCV valve into intake manifold. Guide me please

[@MechanicalBoost]

@@NisarUddin-qc3bk If oil is coming through the PCV valve into the intake manifold and you’re noticing a drop in engine oil levels, there could be a few possible issues to consider: 1) Worn Piston Rings: Worn or damaged piston rings can cause excess blow-by gases to enter the crankcase. This can increase crankcase pressure, pushing more oil through the PCV system and into the intake manifold. This is a common cause of oil loss and blow-by issues. 2) PCV Valve Malfunction: A stuck or faulty PCV valve may cause excess oil vapor to be sucked into the intake manifold. The PCV valve regulates the flow of gases between the crankcase and intake manifold, and if it's clogged or faulty, it may not properly separate oil from the blow-by gases, leading to oil entering the intake manifold. 3) Engine Wear: Over time, engine components such as valve seals and piston rings wear out, leading to oil leakage into the combustion chamber and potentially into the intake via the PCV system. This can lead to excessive oil consumption. 4) High Crankcase Pressure: Ifthere’s excessive pressure in the crankcase, possibly due to clogged oil passages, it can force oil through the PCV system into the intake manifold. This is typically caused by engine wear or restricted ventilation. 5) Clogged Oil Separator or Breather: If the oil separator or breather that is supposed to filter oil from the gases before they enter the intake manifold is clogged or not functioning properly, oil can enter the PCV valve and be sucked into the intake. What You Can Do: Check and Replace PCV Valve: Start by inspecting or replacing the PCV valve if it is clogged or faulty. Compression Test: Conduct a compression or leak-down test to check the condition of the piston rings. Low compression might indicate worn piston rings. Check for Oil Leaks: Inspect for any other leaks around the engine that might contribute to oil loss. Valve Seals: Check the valve seals

[@brianjuarez2920]

Im seeing a lot of white smoke and oil type of liquid coming out the exhaust. Can this be part of the problem?

White smoke usually means that coolant is being burned in the engine, which means that something is drastically wrong. The most common cause of this is a blown head gasket.

[@SaWxRaPz]

I have changed two PCV valves and the sound keeps coming back after 1 whole day of the new product. What causes it can someone explain? The mechanic team we did the fix cannot understand why it happens the whole system is changed they say the car maybe needs the original one cause we put aftermarket i cannot take this anymore.

[@MechanicalBoost]

It sounds like you're dealing with a persistent issue despite replacing the PCV valves. There are a few possibilities for why the noise might keep coming back, even after replacing the parts. Here are some potential causes to consider: 1) Aftermarket Parts Quality: As your mechanic team mentioned, the aftermarket PCV valves might not be performing at the same level as original parts. Some aftermarket components don’t always match OEM (original equipment manufacturer) standards and can cause issues like improper sealing or incorrect pressure regulation. 2) Incorrect Installation: Even though the parts are new, if the PCV valve wasn't installed correctly, it might not be functioning as intended. Small leaks, loose connections, or improper fitment could cause the system to malfunction again. 3) Crankcase Pressure Build-Up: If there is excessive pressure building in the crankcase, even a new PCV valve might not be able to relieve it properly. This could be due to blockages or restrictions elsewhere in the system (like hoses or the oil separator), which could cause abnormal sounds and symptoms. 4) Engine Vacuum Issues: The PCV valve works by using engine vacuum to regulate pressure in the crankcase. If there’s a vacuum leak elsewhere in the system, it could affect how the PCV valve functions, leading to recurring noises. 5) Oil Contamination: If the oil has become contaminated with debris or sludge, it can clog up the PCV system, even after installing a new valve. This could prevent the valve from operating properly and lead to abnormal sounds. If the mechanic suspects the aftermarket PCV valve is the problem, replacing it with an OEM part could help. In the meantime, you might also want to have them inspect the entire PCV system and the engine’s vacuum system to ensure there are no other contributing factors.

[@SaWxRaPz]

The sound today almost vanished and i only hear it for literally the moment i turn off the engine just one quick whinning .

[@DirtyWayLeek]

Can this cause low compression in a cylinder ?

[@MechanicalBoost]

A malfunctioning Positive Crankcase Ventilation (PCV) valve is unlikely to directly cause low compression in an engine cylinder. The PCV valve is primarily responsible for controlling and regulating the flow of blow-by gases from the crankcase back into the intake manifold to be burned in the combustion process.

[@jacobtran3230]

Can the pcv cause bank one sensor 1 to drop voltage???

[@MechanicalBoost]

A bad PCV valve typically wouldn't directly cause a drop in voltage for Bank 1 Sensor 1. However, a malfunctioning PCV valve can lead to conditions that might indirectly affect the oxygen sensor's readings. 1) Air-Fuel Mixture Imbalance: A faulty PCV valve can cause unmetered air to enter the intake manifold, leading to a lean air-fuel mixture. The oxygen sensor might detect this imbalance and show lower voltage readings, as it senses a higher amount of oxygen in the exhaust gases. 2) Engine Performance Issues: If the PCV valve is stuck open or closed, it can cause engine performance issues such as rough idling, misfires, or increased oil consumption. These issues can affect exhaust gas composition, which the oxygen sensor monitors, potentially leading to abnormal sensor readings. If you're seeing a drop in voltage from Bank 1 Sensor 1, it's more likely due to an issue directly related to the sensor, wiring, or the engine's air-fuel mixture rather than the PCV valve itself.

Could bad pcv valve cause slight knocking like sound

[@BobKing-qv7pq]

[@MechanicalBoost]

Yes, a malfunctioning PCV valve can potentially cause engine knocking-like sounds. The PCV valve regulates the flow of gases between the crankcase and the intake manifold. If the valve is stuck open or closed, it can lead to various issues, including increased pressure within the crankcase or improper ventilation. Increased crankcase pressure can result in oil leaks, loss of power, and even engine knocking noises. Knocking noises occur when the air-fuel mixture ignites prematurely in the combustion chamber, causing pressure waves that can sound like knocking or pinging.

A bad PCV valve is unlikely to be the direct cause of white smoke coming out of the air filter. The PCV valve is responsible for regulating the flow of blow-by gases from the engine's crankcase to the intake manifold, where they can be burned in the combustion process.
