Book Excerpt: 1983-1993 Chevrolet S-10 Blazer, GMC S-15 Jimmy, Typhoon, Olds Bravada Repair Manual ENGINE AND ENGINE OVERHAUL
VALVE STEM SEALS CYLINDER HEAD INSTALLED
(See Figures 152, 153, 154, 155 and 156) The valve stem seals on most engines covered by this manual may be replaced with the cylinder head either on or off the engine. The removal procedure with the cylinder head installed utilizes compressed air in the cylinder to hold the valve in place and keep it from dropping into the cylinder once the valve keeper, cap and spring are removed. NOTE: If air pressure is lost while the valve keepers are removed, the valve will drop into the cylinder. If this happens, the cylinder head must be removed in order to recover the valve.
  1. Disconnect the negative battery cable.
  2. Remove the rocker arm cover.
  3. NOTE: The cylinder must be at TDC of its compression stroke in order to follow this procedure. On the compression stroke, the cylinder's valves will be closed allowing the air pressure to hold the valve in position. The engine must therefore be turned slightly for each cylinder's valve seals.
  4. Remove the rocker arm and pushrod assemblies from the cylinders for which the valves are being serviced.
  5. Remove the spark plug from the cylinder which is on its compression stroke and install a spark plug air fitting adapter with an in-line gauge set between the adapter and air compressor. Apply compressed air to hold the valve in place.
  6. Compress the valve spring using a suitable compressor tool and remove the valve keeper. Carefully release the spring tension, and then remove the valve cap and spring.

EMISSION CONTROLS
TESTING AIR INJECTION PUMP
(See Figures 31, 32 and 33) Accelerate the engine to approximately 1500 rpm and observe the air flow from hose(s). If the air flow increases as the engine is accelerated, the pump is operating satisfactorily. If the air flow does not increase or is not present, proceed as follows:
  1. Check for proper drive belt tension. The Air Management System is not completely noiseless. Under normal conditions, noise rises in pitch as the engine speed increases. To determine if excessive noise is present, operate the engine with the pump drive belt removed. If excessive noise does not exist with the belt removed, proceed as follows:
  2. Check for a seized Air Injection Pump. DO NOT oil the air pump.
  3. Check the hoses, the pipes and all connections for leaks and proper routing.
  4. Check the air control valve.
  5. Check air injection pump for proper mounting and bolt torque.
  6. Repair irregularities in these components, as necessary.
  7. If no irregularities exist and the air injection pump noise is still excessive, replace the pump.
