Does the 2018 RAM 3.6 Engine Require PCV Valve Replacement?

AvatarByHarold Trujillo Desktops & PC Builds

When it comes to maintaining the performance and longevity of your 2018 RAM equipped with the 3.6-liter engine, understanding the components that keep your vehicle running smoothly is essential. One such component that often raises questions among RAM owners is the PCV valve, a small but crucial part of the engine’s ventilation system. Whether you’re a seasoned mechanic or a curious vehicle owner, knowing if your 2018 RAM’s 3.6 engine requires a PCV valve replacement can save you time, money, and potential engine trouble down the road.

The PCV (Positive Crankcase Ventilation) valve plays a vital role in controlling harmful emissions and maintaining engine efficiency by regulating the flow of gases within the engine crankcase. Over time, this valve can wear out or become clogged, which may lead to performance issues or increased emissions. For RAM owners, understanding the maintenance needs of the PCV valve specifically for the 3.6-liter engine is key to ensuring optimal engine health and avoiding unexpected repairs.

In the following sections, we’ll explore whether the 2018 RAM 3.6 engine includes a PCV valve that requires replacement, how to identify signs of wear or failure, and what steps you can take to keep your engine running at its best. This

PCV Valve Function and Location in the 2018 RAM 3.6L Engine

The Positive Crankcase Ventilation (PCV) valve plays a critical role in the emission control system of the 2018 RAM with the 3.6L Pentastar V6 engine. Its primary function is to regulate the release of gases from the crankcase, preventing harmful emissions and maintaining engine efficiency. The PCV valve directs blow-by gases back into the intake manifold to be burned during combustion rather than vented directly into the atmosphere.

In the 2018 RAM 3.6L engine, the PCV valve is integrated as part of the valve cover assembly rather than a standalone component. This design means that the PCV valve is not a separate, easily replaceable part as found in older engine models. Instead, the valve cover houses the valve mechanism, and any issues with the PCV system often necessitate valve cover replacement or servicing.

The PCV valve location specifics:

  • Mounted on the top side of the valve cover.
  • Connected by a hose to the intake manifold to route crankcase gases.
  • Accessible by removing the valve cover, which requires engine disassembly.

Because of this integration, the PCV valve is less prone to being replaced individually during routine maintenance, but it is still a critical component monitored for proper function.

Signs of PCV Valve Issues and Replacement Considerations

Diagnosing PCV valve problems in the 2018 RAM 3.6L engine can be challenging due to its integrated design. However, symptoms indicating a malfunctioning PCV system include:

  • Rough engine idle or stalling.
  • Increased oil consumption or oil leaks around the valve cover.
  • Check Engine Light (CEL) illumination with codes related to crankcase ventilation.
  • Excessive engine oil sludge buildup.
  • Poor fuel economy or increased emissions.

When these symptoms arise, a thorough inspection is warranted. Since the PCV valve is part of the valve cover assembly, replacement typically involves:

  • Removing the valve cover to access the integrated PCV valve.
  • Inspecting and possibly replacing the valve cover gasket to prevent oil leaks.
  • Cleaning or replacing the entire valve cover assembly if the PCV valve is clogged or damaged.

Due to the complexity, professional service is often recommended to ensure correct diagnosis and repair.

Maintenance Tips for the PCV System in the 2018 RAM 3.6L Engine

Maintaining the PCV system helps preserve engine performance and longevity. Recommended practices include:

  • Regular oil changes using manufacturer-specified oil to prevent sludge buildup.
  • Periodic inspection of the valve cover area for oil leaks or signs of PCV system wear.
  • Monitoring engine performance and addressing Check Engine Light alerts promptly.
  • Using diagnostic tools to check for any PCV-related trouble codes during routine service.

Adhering to these maintenance habits can mitigate the risk of PCV valve failure and associated engine problems.

Replacement Cost and Labor Overview

Given the integrated design of the PCV valve within the valve cover of the 2018 RAM 3.6L engine, replacement costs and labor are influenced by several factors:

Component/Service Estimated Cost Range Labor Time Notes
Valve Cover with Integrated PCV Valve $150 – $350 – OEM parts preferred for durability
Valve Cover Gasket $20 – $50 – Recommended to replace during valve cover service
Labor for Removal and Replacement – 1.5 to 3 hours Varies based on shop rates and engine configuration
Total Estimated Repair Cost $250 – $600 – Includes parts and labor

Labor time accounts for the complexity of removing components to reach the valve cover and ensuring a proper seal upon reinstallation. Because the PCV valve is not a standalone part, partial repairs are uncommon, and cost efficiency comes from comprehensive servicing.

Aftermarket Solutions and Modifications

Some vehicle owners consider aftermarket PCV valve kits or performance upgrades. For the 2018 RAM 3.6L engine, aftermarket solutions are limited due to the integrated valve cover design. However, options include:

  • Valve cover replacement with enhanced PCV valve designs for improved flow.
  • Oil catch cans installed in the crankcase ventilation line to reduce oil vapor contamination.
  • Upgraded gaskets and seals to prevent leaks in high-performance or heavy-duty use cases.

Before implementing aftermarket modifications, it is essential to verify compatibility and warranty impact. Consulting with a qualified technician or RAM specialist can help determine the best course of action for PCV system improvements.

PCV Valve Replacement on 2018 RAM 3.6L Engine

The 2018 RAM equipped with the 3.6L Pentastar V6 engine utilizes a Positive Crankcase Ventilation (PCV) system that is integral to managing crankcase gases and maintaining engine efficiency. Unlike older engine designs that often featured a standalone PCV valve, this engine employs a more integrated design within the valve cover and intake manifold assembly.

Key points regarding the PCV valve and its replacement on the 2018 RAM 3.6L engine include:

  • Integrated PCV System: The PCV valve is part of the valve cover assembly and the intake manifold connection, rather than a separate, easily replaceable valve.
  • Replacement Considerations: Because the PCV valve is integrated, it is not typically serviced or replaced as an individual component during routine maintenance.
  • Symptoms Indicating PCV Issues: Engine oil leaks, rough idle, increased oil consumption, or check engine light codes related to the crankcase ventilation system may suggest PCV system faults.
  • Service Procedure: If the PCV system requires attention, the valve cover or associated hoses and grommets may be replaced as part of the repair.

PCV Valve Location and Replacement Details

Component Location Replacement Method Notes
PCV Valve Integrated into the driver side valve cover and intake manifold Replace valve cover or intake manifold components as needed No separate PCV valve available; system serviced as an assembly
PCV Hose Between valve cover and intake manifold Inspect for cracks or leaks; replace hose if damaged Common wear item, easier to replace than valve cover

Maintenance Recommendations for the PCV System

Maintaining the PCV system on the 2018 RAM 3.6L engine involves regular inspection and addressing any symptoms early to prevent more serious engine issues:

  • During routine oil changes, inspect the PCV hose and valve cover area for signs of oil leaks or damage.
  • Listen for hissing noises from the valve cover area, which may indicate a vacuum leak related to the PCV system.
  • If a diagnostic trouble code (DTC) related to crankcase ventilation (such as P0171, P0174, or P0456) is present, verify the PCV system components and replace as necessary.
  • Consult the factory service manual or a certified technician for specific procedures related to PCV system service on this engine.
