Restriction Of Air Inlet And Exhaust
Engine horsepower and efficiency will be reduced if either the air inlet or exhaust system becomes restricted.The air cleaner should not restrict air flow more than 30 in. (762 mm) of water difference in pressure.Exhaust back pressure (pressure difference measured between the turbocharger outlet elbow tap and ambient air) should be no more than 15 in. (381 mm) of water. Back pressure for naturally aspirated engines, should be no more than 25 in. (635 mm) of water, measured between exhaust outlet and ambient air.Crankcase Pressure
Crankcase pressure (difference from ambient) above 3 in. (76,2 mm) of water is excessive and can be a result of combustion gas leaking past broken or damaged pistons and/or piston rings. This condition will usually be accompanied by irregular engine operation and excess fumes from crankcase breather opening. This condition can cause the breather element to become restricted in an unusually short time. In addition, excessive pressure can cause engine oil to leak past gaskets and seals that would function properly under normal conditions.Compression
Irregular (rough) engine operation can be caused by improperly adjusted or leaky valves. Operate the engine at RPM which makes the malfunction most pronounced. A non-firing or low compression cylinder can be located by removing spark plug wires one at a time. Continue this until a removed wire makes little or no difference in the engine operation. This same test can also indicate faulty spark plugs so further checking of the cylinder is necessary.The preceding test is merely a quick means of pinpointing the source of cylinder compression loss. Removal of the head and visual inspection of the valves and seats is necessary to check for minor valve defects which do not have much effect on engine operation. This is usually done during general engine reconditioning.The following procedure provides a more complete check of the sealing ability of the individual valves without removing the cylinder head:1. Remove the spark plug with 1P7424 Spark Plug Socket leaving the spark plug adapter in place.2. Adapt an air hose to the spark plug adapter. This can be
