- Disconnect the Positive Crankcase Ventilation (PCV) hose at the air box and then install a manometer to the fresh air line. Start the vehicle and let the engine idle. Check to see if there is a positive or negative pressure on the manometer gauge. Increase engine RPM to 1500 RPM for 2-3 seconds. Determine if there is positive or negative pressure on the manometer gauge. If the manometer gauge indicates zero or positive pressure when the engine RPM is raised, the PCV port in the intake manifold needs to be unplugged. The intake manifold will need to be removed to unplug the PCV port.
- Lubricate and check chassis. Change oil and oil filter. Check air filter and breather filter. Check all fluid levels and tire pressures. Preform basic safety inspection. Road test vehicle.
