The PCV system is designed to prevent blow-by gas from escaping to the atmosphere by drawing it directly into the intake manifold. The PCV valve contains a spring-loaded plunger which is lifted in proportion to intake manifold vacuum. Under high vacuum, blow-by is returned directly to the manifold through the breather chamber and PCV valve with fresh air. When intake manifold vacuum decreases (wide open throttle) and vacuum in the air cleaner increases, the PCV valve closes and the blow-by is returned through the cylinder head cover breather hose and into the air cleaner. The PCV valve also acts as a check valve when the engine backfires to prevent crankcase explosion. Fig. 1: PCV system components-1984-87 1.5L engines Fig. 2: PCV system components-1988-91 1.6L engines Fig. 3: PCV system components-1992-95 engines Fig. 4: PCV system components-1984-87 carbureted engines SERVICE Positive Crankcase Ventilation (PCV) Valve For PCV valve removal, refer to Routine Maintenance of this information. 1. Locate the PCV valve. With the engine running at idle, use pliers to pinch the PCV hose between the valve and the intake manifold. It should be possible to hear the spring loaded valve click shut. 2. If no click is heard, remove the valve from the engine but leave it connected to the intake manifold. A hissing sound should be heard and vacuum should be felt at the valve inlet. 3. If no vacuum is felt, remove the valve from the intake manifold hose. The engine should stall or almost stall. This will indicate a stuck valve or clogged hose. Check the breather hose for clogging or leaks and replace any defective parts. Exhaust Gas Recirculation (EGR) System FUEL INJECTED ENGINES General Information See Figure 3 The Exhaust Gas Recirculation (EGR) system is used to control emissions measured at the tailpipe. Components included are the EGR valve and controls. The EGR system uses a poppet type valve to regulate the amount of exhaust gas flowing into the intake manifold. The flow path is cast into the cylinder head and does not use any external tubing. A control solenoid valve regulates the amount of vacuum to the EGR valve. A Constant Volume Control (CVC) valve provides a constant amount of vacuum to the control solenoid valve over a wide range of engine vacuum. When servicing or repairing any part of the emissions system, it is absolutely essential to check for any obvious mechanical faults or failures. Remember, a trouble code only indicates which sensor or circuit is affected by the problem. Simple mechanical faults such as a vacuum leak or poor electrical connection can cause a fault code. The EGR valve is not simply open or closed but is modulated by controlling the amount of engine vacuum to the valve diaphragm, up to a maximum of 8 in. Hg of vacuum. The EGR valve has a sensor in the top of the valve that reports valve lift to the ECU (same as ECM, 1992-95). The ECU modulates the position of the control solenoid valve to control the EGR valve lift according to an internal program. Upstream of the control solenoid valve, the CVC provides a constant supply of vacuum so EGR control is precise under all manifold vacuum conditions

The distinguishing characteristic of this condition is that it likely will have been present since new, and is typically noticed within the first 161-322 km (100-200 mi). The noise may often be diagnosed as a collapsed lifter . Additionally, the noise may be present at cold start and appear to diminish and then return as the engine warms to operating temperature. This noise is different from other noises that may begin to occur at 3219-4828 km (2000-3000 mi). Cause The 0-ring seal between the oil pump screen and the oil pump may be cut, causing aeration of the oil. Correction

Figure 1 – Fittings and Vacuum Port Locations INSTALLATION PROCEDURE BEFORE REMOVING OLD CARBURETOR 1. Determine if the distributor vacuum port is timed (no vacuum at idle) or full (vacuum present at idle). With the engine at operating temperature and idling, pull the vacuum advance hose off of the carburetor and “feel”for vacuum by putting your finger on the vacuum port (See Fig. 2) . If your distributor has timed vacuum advance, you will hook the vacuum hose from the distributor to the passenger side vacuum port on the new carburetor. If it has full vacuum advance, it will be hooked up to the driver side port. 2. The stock steel fuel line must be converted to fuel resistant rubber hose. The stock steel line will not connect to the Performer Series Carburetor. Use Edelbrock Universal Fuel Line Kit #8135. This kit contains a filter, neoprene hose, and fittings to adapt to 5/16″or 3/8″stock steel fuel lines (See Fig. 3) . NOTE: After cutting the steel line, remove sharp edges and clean out any chips. 3. Always use a new fuel filter. Failure to do so will void your warranty. 4. You must use Edelbrock Adapter #2696 or Adapter & Fuel Line Kit #2697 when installing a Performer Series carburetor on a General Motors Quadrajet or Chrysler Thermoquad intake manifold. #2697 includes adapter #2696 and fuel line kit #8135. Do not use an open adapter! (See Fig. 4) 5. You must use Edelbrock Adapter #2732 when installing a Performer Series carburetor on certain Edelbrock intake manifolds. In those applications, install the adapter as shown (See Fig. 5)

1. Based upon stored fault codes for secondary air system, there is little or no flow of secondary air into engine. Typical causes for this issue are failed secondary air pumps and/or secondary air check valves. Secondary air pump should operate under normal circumstances when vehicle is first started to perform system test. Pump will normally be heard running when standing in front right corner of vehicle. 2. The secondary air pump is located in the right front of engine compartment. A secondary air pump relay located in the glove box is controlled by the engine control module and sends power to the secondary air pump. 3. Air pump can be disconnected and supplied with power and ground at pump to verify operation is possible. 4. Check valve on front right of cylinder head can be supplied with vacuum and visually checked for opening of valve. 5. Vacuum line from check valve to operating solenoid should also be inspected for cracks or being disconnected. Vacuum line follows right side of cylinder head to back of cylinder head to the secondary air solenoid located under left rear side of intake manifold. 6. The solenoid should allow vacuum flow to the check valve during vacuum pump operation. The solenoid is controlled directly by the engine control module and receives power during key-on-engine-off. Potential Causes: A.I.R. Check Valve Engine Control Module (ECM) Codes — Engine control module fault.
