PCV Valve

The first step to replace positive crankcase ventilation (PCV) valve (L36) includes removing the fuel injector sight shield before taking out the MAP Sensor. Turn the 16 mm (5/8 inch) socket to press down on the access cover then rotate it a quarter turn to the counterclockwise direction before pulling it off. The process starts with unfastening the PCV Valve while removing its o-ring from Intake Manifold positioning. You must place the Intake Manifold's PCV Valve along with o-ring followed by attachment of the access cover. The installation order needs you to replace the MAP Sensor and conclude with the fuel injector sight shield.

The first step to replace the Positive Crankcase Ventilation (PCV) valve is to pull off the vacuum hoses from the fuel pressure regulator and the PCV valve , then take out the PCV valve . Place the new PCV valve in your engine, then connect the vacuum hoses to each of the fuel pressure regulator and the PCV valve .

A technician must disconnect three vacuum hoses from their respective valves. After this step, the PCV Valve can be removed easily. To install the new PCV Valve position it correctly before securing the vacuum hoses to the Fuel Pressure Regulator and PCV Valve simultaneously.

Service of the positive crankcase ventilation valve requires fuel injector sight shield and MAP Sensor removal before proceeding with the next steps. The 16 mm socket allows you to depress and turn the access cover 1/4 turn counterclockwise to extract it. Take out the PCV Valve combined with the o-ring from the Intake Manifold after completing this task. Return the PCV Valve together with the o-ring into the Intake Manifold before reinstalling the access cover . Then install the MAP Sensor and complete the repair with the fuel injector sight shield.

The replacement process for positive crankcase ventilation (PCV) valve begins with fuel injector sight shield removal followed by disconnecting the MAP Sensor electrical connector then removing the MAP Sensor. Position the access cover downwards using a 16 mm (5/8 inch) socket then rotate it counterclockwise 1/4 turn to eliminate it. You need to remove the PCV Valve together with its o-ring from the Intake Manifold. First step for installation is to add the new o-ring and the PCV Valve before putting on the access cover . The complete procedure includes reinstalling the MAP Sensor while reconnecting its electrical connector before putting back the fuel injector sight shield.

The first step in PCV Valve replacement requires disconnecting the vacuum hose from this valve while removing it from service. Install the positive crankcase ventilation valve first before connecting its vacuum hose to the valve.

The positive crankcase ventilation (PCV) valve replacement starts with removing the fuel injector sight shield after disconnecting the MAP Sensor electrical connector and removing the MAP Sensor. A 16 mm (5/8 inch) socket should be used to push down the access cover then rotate it one quarter turn in the counterclockwise direction before removing it. Before proceeding with the replacement remove the PCV Valve along with its o-ring from the Intake Manifold. Begin by positioning both the PCV Valve along with the new o-ring before installing the access cover . The installation process involves first reinstalling the MAP Sensor before reinstalling its electrical connector and ending the operation by putting on the fuel injector sight shield.

Start the Positive Crankcase Ventilation Valve service by using fingers to hold down the valve cover and then remove its two retaining bolts. You must first remove the PCV valve cover before proceeding to take out the PCV valve alongside its spring and O-ring component. Reinstall the PCV valve followed by its spring and O-ring in their original position during installation. Readers need to pay attention to the service precaution notice that appears in the Fastener section. You should install the PCV valve cover along with a new gasket if required before you start the hand-driven bolts by two. Secure the two cover retaining bolts at 12 N.m (106 lb in).

The PCV valve and its valve rocker arm cover operate as one unit so they must be replaced together. Proceed to remove first the left valve rocker arm cover followed by unscrewing all screws from the PCV baffle before taking out the PCV baffle. Evaluating the necessity to clean the PCV valve leads to replacement of the valve cover when needed. Installation starts with placing the PCV baffle into position before using the Fastener Notice from Service Precautions to secure the PCV baffle screws at 6 Nm (53 inch lbs.). Complete the installation process by fitting the left valve rocker arm cover at its specified position.

The Positive Crankcase Ventilation (PCV) Valve replacement requires you to unplug vacuum hoses from the fuel pressure regulator as well as positive crankcase ventilation valve before removing the positive crankcase ventilation valve. The installation process requires users to install the positive crankcase ventilation valve while connecting vacuum hoses to fuel pressure regulator and positive crankcase ventilation valve .

Prior to installing or replacing the Positive Crankcase Ventilation (PCV) Valve beginners must disconnect the vacuum hose from the positive crankcase ventilation valve before proceeding to detach the valve. The positive crankcase ventilation valve installation requires both steps of valve positioning and attaching the vacuum hose to the valve.

You should begin by switching OFF the vehicle's ignition. Use your hands to take out both vacuum hoses and the valve. Install the new positive crankcase ventilation valve, then connect both ends of the vacuum hoses into place.

The replacement process of the positive crankcase ventilation (PCV) valve requires step one to be the removal of the fuel injector sight shield followed by disconnecting the MAP Sensor electrical connector and dismantling the MAP Sensor. The 16 mm (5/8 inch) socket must press down the access cover which can then be turned counterclockwise by 1/4 turn to remove it. Start by removing the PCV Valve accompanied by its o-ring from the Intake Manifold. The first step is to install the new o-ring together with the PCV Valve in their designated positions and to then put back the access cover. After replacing the MAP Sensor install it with correct electrical connector connection before you put the fuel injector sight shield back into place.

Start by taking off the vacuum lines attached to the fuel pressure regulator and the PCV valve to replace the PCV valve. Now, get the PCV valve out of the system. Place the fresh PCV valve at the right spot and then put the vacuum hoses back onto the fuel pressure regulator and PCV valve .

The positive crankcase ventilation (PCV) valve requires complete replacement alongside the valve rocker arm cover because they come as a single assembly. As a first step you need to take off the left valve rocker arm cover. Cleaning the non-defective PCV valve can replace the need for rocker arm cover replacement. To proceed with the PCV valve cleaning process first detach its screws from the PCV baffle. The valve cover requires a new replacement when the PCV valve becomes defective or when cleaning proves ineffective. You must employ the right fasteners at their proper positions based on specified part numbers for installation. The service procedure specifies which fasteners need replacement as well as the appropriate usage of thread locking compounds and sealants. The use of paints and lubricants together with corrosion inhibitors must be avoided on fasteners and their joint surfaces because they can alter torque settings and clamping force and possibly harm the fastener. The correct fastening procedures with their specific sequences should be followed to prevent damage to components and subsystems. The service procedure calls for assembly of the PCV baffle before securing its screws at 6 Nm (53 lb in). Finally install the left valve rocker arm cover.
