@GLHF Yeah, they redesign the pcv valve for this engine. It's 2 bolts opposed to 3. The old hose also won't fit the new pcv valve, so you're buying a new hose as well. They both come to around $50-ish to buy as a pair, even at Autozone, for the Pentastar 3.6L .. I'd never buy or take anything to a dealership other than for programming.

I've heard about malfunctioning PCV valves from a number of sources over the years, but never took the time to really dig into the specifics. Your detailed explanations of the possible impact of a failed PCV valve were super-clear and informative. I've been seeing light white smoke from my exhaust pipes over the past 10K miles or so, even when the engine is hot, which was one of the symptoms that you mentioned in your video. I'll be replacing the PCV valve to see if this corrects the problem. Thanks for your super-useful information!

The PCV valve doesn’t allow fresh air in. It recirculates blow by gasses back into the manifold. The intake breather hose brings in the fresh air.

@CLICKANDLEARNCh 9 ай бұрын

Thank you for your comment! You're absolutely correct. The PCV (Positive Crankcase Ventilation) valve's primary function is to recirculate blow-by gases back into the intake manifold, which helps reduce emissions by reintroducing them into the combustion process. On the other hand, the intake breather hose is responsible for bringing fresh air into the crankcase to ensure proper ventilation and prevent pressure buildup. Both components work together to maintain engine efficiency and emissions control. Appreciate your input!

Hello I have Mercedes Vito Euro 6 diesel, and getting heavy greyish/bluish smoke from exhaust, I’ve changed DPF pressure sensor and cleaned the DPF filter, this lasted 1 day with no smoke, Now it’s back, I get a strong smell of oil aswell as smoke from exhaust, could it be bad PCV Valve?

@CLICKANDLEARNCh 2 ай бұрын

Thanks for reaching out! From the symptoms you’ve described-heavy greyish/blue smoke and the strong smell of oil-it’s possible that a faulty PCV (Positive Crankcase Ventilation) valve could be the cause. A bad PCV valve can allow oil to enter the intake, leading to excessive oil burning, which results in smoke and the smell of oil from the exhaust. However, since you’ve already cleaned the DPF and replaced the pressure sensor, it might also be worth checking the turbocharger seals or any other potential oil leaks, as these could also cause similar symptoms. We’d be happy to take a closer look at SANU Motors if you need further diagnosis. Feel free to bring your Mercedes Vito by the garage for a more thorough inspection. Thanks again for your question, and we hope to help you get this resolved!

When you replace the PCV (Positive Crankcase Ventilation) valve in your 2009 Scirocco 2.0 TFSI and experience problems and error codes the following day, it could be due to several reasons: 1. **Defective or Incorrect PCV Valve**: Even though you installed a new OEM PCV valve, it's possible that the part is defective. Manufacturing defects can occur even with new parts. Double-check that the part number matches the specific requirements for your vehicle. 2. **Installation Issues**: If the PCV valve wasn't installed correctly, it might not be sealing properly or could be loose, leading to continued issues. Verify that the PCV valve is seated properly and that all connections are secure. 3. **Related Components**: The PCV system involves several components, including hoses, seals, and connections. If there’s a crack or leak in any of these, it could cause problems similar to those experienced before replacing the PCV valve. Inspect the surrounding components for any signs of wear or damage. 4. **Engine Oil**: Sometimes, a faulty PCV valve can cause excess oil consumption or oil contamination in the intake system. If there's oil in the intake, it might be necessary to clean the intake system, throttle body, and related components to resolve the issue. 5. **Check Engine Light Codes**: If the error returned, the car's ECU (Engine Control Unit) might have stored specific codes that could help diagnose the issue. Reading these codes with an OBD-II scanner can provide insights into what's going wrong. 6. **Software/ECU Issues**: Occasionally, the ECU might need a reset or an update after replacing certain components like the PCV valve. Consider resetting the ECU or having it checked for any required updates. 7. **Secondary Problems**: The initial PCV valve issue might have caused other components to fail or get damaged. For example, if the PCV valve was malfunctioning for a long time, it could have caused issues with the turbo, vacuum system, or other related systems. 8. **Boost Leaks**: Since the 2.0 TFSI engine is turbocharged, any issue with the PCV system could affect boost pressure. If there is a leak, it might lead to performance issues and errors. I recommend scanning the vehicle for error codes to get a more precise diagnosis. If the problem persists despite the new PCV valve, it might be worth consulting with a specialist familiar with Volkswagen engines to ensure that no other underlying issues are being overlooked.

Installing an oil catch can and performing an EGR (Exhaust Gas Recirculation) delete are popular modifications among turbocharged engine enthusiasts, particularly those with the 2.0 TFSI engine. These modifications can indeed help mitigate some of the common issues associated with the PCV system and EGR valve. Here's why these modifications worked for you: ### 1. **Oil Catch Can Installation:** - **Prevents Oil in the Intake System**: The oil catch can captures oil vapors and other contaminants before they can enter the intake system. This prevents oil from accumulating in the turbo hoses, intercooler, and intake manifold, which can lead to performance issues, rough idling, and smoke during acceleration. - **Improved Engine Performance**: By ensuring that only clean air reaches the turbo, the engine can perform more efficiently. This results in smoother acceleration and reduced risk of carbon buildup in the intake system. ### 2. **EGR Delete:** - **Reduces Soot and Carbon Buildup**: The EGR system recirculates a portion of the exhaust gases back into the intake, which can lead to carbon buildup over time. Deleting the EGR system prevents this buildup, leading to a cleaner intake tract and improved engine performance. - **Lower Intake Air Temperatures**: By eliminating the EGR system, the intake air remains cooler, which is beneficial for combustion efficiency and power output, especially in turbocharged engines. ### 3. **Improved Engine Longevity:** - **Cleaner Turbo System**: With the oil catch can in place and the EGR deleted, your turbo system is likely to stay cleaner, which reduces wear and tear on the turbocharger and related components. - **Less Oil Consumption**: As the catch can prevents oil from entering the intake, your engine may consume less oil, leading to longer intervals between oil changes and less frequent topping up of oil. ### 4. **Elimination of Common Issues:** - **Rough Idle**: The rough idle you experienced was likely due to oil and carbon buildup in the intake system. By installing the catch can and deleting the EGR, you've addressed the root cause of this problem. - **Blue Smoke on Startup**: Blue smoke is typically a sign of burning oil, which was likely being introduced into the intake through the PCV system. The catch can prevents this, eliminating the smoke. ### 5. **Cleaner Combustion:** - **Better Air-Fuel Mixture**: With only clean air entering the combustion chamber, the air-fuel mixture is more consistent, leading to more efficient combustion and better overall engine performance. Your approach has effectively addressed the common problems associated with the PCV and EGR systems in the 2.0 TFSI engine. While these modifications can provide significant benefits, it’s important to note that EGR deletes may not be legal in all regions due to emissions regulations. Always consider the legal implications of such modifications based on your location.

Years ago this was the engine crankcase breather pipe nothing more. New cars cannot breath and become unhealthy.

@CLICKANDLEARNCh 11 ай бұрын

ChatGPT The concept of an engine crankcase breather pipe, also known as a crankcase ventilation system or PCV (Positive Crankcase Ventilation) system, has evolved over the years in automotive design. Its primary purpose is to vent harmful gases and excess pressure from the engine's crankcase to prevent various issues such as excessive pressure buildup, oil contamination, and emissions of harmful pollutants. In older vehicles, the crankcase breather pipe may have been a simple vent that released gases directly into the atmosphere, which could contribute to air pollution. Modern cars have more advanced PCV systems that route these gases back into the intake manifold to be burned in the combustion process. This helps reduce emissions and improve fuel efficiency. If a modern car's PCV system is not functioning correctly, it can lead to various problems, such as increased oil consumption, reduced fuel efficiency, and potential damage to engine components. Regular maintenance and checking of the PCV system are essential to ensure the engine operates efficiently and cleanly. It's essential to follow the manufacturer's recommended maintenance schedule and use quality parts and fluids to keep your car's engine in good health and minimize its impact on the environment. If you suspect your car's PCV system is not functioning correctly, it's advisable to have it inspected and repaired by a qualified mechanic thank you very much for the feedback really appreciated

Both the EGR (Exhaust Gas Recirculation) system and the PCV (Positive Crankcase Ventilation) valve are potential culprits for smoking issues in a car like your Audi A3. Here's a breakdown of each: EGR System: If the EGR system is malfunctioning, it could lead to excess exhaust gases being reintroduced into the combustion chamber, potentially causing smoke from the exhaust. Common symptoms of a faulty EGR system include rough idling, engine knocking, and decreased fuel efficiency. PCV Valve: A malfunctioning PCV valve can cause excessive pressure buildup in the crankcase, leading to oil leaks and ultimately smoke from the exhaust. Symptoms of a faulty PCV valve may include high oil consumption, rough idling, and poor engine performance. To determine which component is causing the smoking issue in your Audi A3, you may need to perform diagnostic tests or consult with a qualified mechanic. They can use diagnostic tools to check for fault codes and perform visual inspections of the EGR system and PCV valve. Additionally, they may conduct a compression test to assess the overall health of the engine. In any case, addressing the issue promptly is essential to prevent further damage to your vehicle and ensure its optimal performance.

PCV are inexpensive and should be changed every five years anyways. While you do your basic tune up change the ERG valve at the same time along with the air cleaner and oil change. The MAF sensor is typically OK but can also be cleaned at this time with just 50% rubbing alcohol in a spray bottle. After cleaning the MAF sensor just let the MAF sensor dry itself in the sun for 30 minutes before reinstalling. No need to buy that expensive MAF sensor cleaner at the auto-parts store.

Bro is that the bad pcv! And my car engine oil came out from dipstick and spread away

@CLICKANDLEARNCh Ай бұрын

If engine oil is coming out of the dipstick tube, a bad PCV (Positive Crankcase Ventilation) valve could indeed be the culprit. Here’s how a faulty PCV valve could lead to the symptoms you’re seeing: ### Symptoms of a Bad PCV Valve: 1. **Oil Leaks and Oil Blowing Out of the Dipstick Tube**: When the PCV valve is stuck closed or clogged, it can’t vent the crankcase gases properly. This causes pressure to build up in the crankcase, forcing oil out of weak points like the dipstick tube, valve cover gaskets, or other seals. 2. **High or Rough Idle**: A stuck-open PCV valve can cause too much air to enter the intake, leading to a high or uneven idle. 3. **Whistling or Hissing Noise**: If the valve or related hoses are leaking, it can create a whistling sound, often noticeable at idle. 4. **Increased Oil Consumption and Possible Blue Smoke**: A stuck-open PCV can pull oil mist into the intake manifold, burning it and leading to blue smoke from the exhaust. 5. **Check Engine Light**: Lean codes or misfire codes (like P2187 in your case) can be triggered by a bad PCV valve as it disrupts the air-fuel mixture. ### Next Steps: 1. **Check the PCV Valve**: Remove the PCV valve and shake it. A functional valve will make a rattling sound. If it’s clogged or doesn’t rattle, it needs to be replaced. 2. **Inspect PCV Hoses**: Check for any collapsed or cracked hoses that could disrupt proper crankcase ventilation. 3. **Replace the Valve** (if needed): A new PCV valve is usually affordable and straightforward to replace. This simple replacement can relieve the crankcase pressure and prevent further oil from blowing out of the dipstick tube. Hopefully, this clears things up! Replacing the PCV should help reduce or stop oil from being forced out, but let me know if anything else is acting up.

If there is a leak from the air intake and pcv hose, would it cause the same problems ?

@CLICKANDLEARNCh 11 ай бұрын

A leak from the air intake or PCV (Positive Crankcase Ventilation) hose in your vehicle can potentially cause various problems, but the specific issues it might lead to can vary depending on the location and severity of the leak. Here are some general problems that can result from such leaks: Decreased engine performance: Air leaks in the intake system can allow unfiltered air to enter the engine, which can disrupt the air-to-fuel ratio and affect combustion. This may result in decreased engine power, rough idling, poor acceleration, and reduced fuel efficiency. Check engine light: A leak in the intake or PCV system may trigger the check engine light on your vehicle's dashboard. This can happen if the leak affects the proper functioning of sensors that monitor air intake or emissions. Poor fuel economy: Unmetered air entering the engine can lead to a lean air-fuel mixture, which may result in poor fuel economy as the engine tries to compensate by injecting more fuel. Increased emissions: Leaks in the PCV system can allow unfiltered crankcase gases to escape into the atmosphere, potentially increasing harmful emissions. This can also impact your vehicle's compliance with emissions regulations. Rough idling and stalling: Air leaks can disrupt the engine's idle stability and lead to rough idling or even stalling in extreme cases. Engine damage: In severe cases, prolonged exposure to unfiltered air or excessive oil vapor escaping from the PCV system can lead to engine damage over time. It's essential to address air intake and PCV hose leaks promptly to prevent these issues and maintain your vehicle's performance and reliability. The specific problems and their severity will depend on the size and location of the leaks, as well as the make and model of your vehicle. If you suspect such leaks, it's advisable to have a qualified mechanic inspect and repair the affected components to avoid potential damage and ensure your vehicle operates as intended. thank you

Hey there! Thank you for this great video. I have a question: can a bad PCV go wrong and still not throw a code?

@CLICKANDLEARNCh 9 ай бұрын

Hello! I'm glad you found the video helpful. To address your question, yes, it's possible for a malfunctioning Positive Crankcase Ventilation (PCV) valve to not always trigger a diagnostic trouble code (DTC). The PCV valve's primary function is to regulate the flow of gases between the crankcase and the intake manifold. If it fails or becomes clogged, it can cause various issues such as poor engine performance, increased oil consumption, rough idling, and even excessive smoke from the exhaust. However, whether a PCV valve issue triggers a diagnostic trouble code depends on the vehicle's make and model, as well as the specific conditions of the malfunction. Some modern vehicles have sophisticated engine management systems that can detect certain faults and trigger corresponding codes, while others may not have sensors or monitoring systems in place specifically for the PCV valve. Additionally, if the issue is intermittent or hasn't reached a threshold level of severity, it might not trigger a code immediately. It's also possible for a PCV valve problem to manifest in ways that aren't directly linked to a specific code, making diagnosis more challenging. If you suspect a problem with your PCV valve but aren't seeing any codes, it's still worth investigating further, especially if you're experiencing symptoms like those mentioned earlier. Regular maintenance checks, including inspection and potential replacement of the PCV valve as part of routine service, can help prevent issues from escalating. Thank You
