TECHNICAL INFORMATION
A faulty air induction system is normally a significant source of
silicon in engine oil. Antifoaming agents in engine normally
contain silicone which will give 3 to 7 PPM in new oil. Silicone is
used in "Print-O-Seal" cylinder head gaskets and crankshaft seals
for engine which normally show 20 to 30 PPM silicone in the oil.
Aluminum and cast iron parts in the engine can have significant
amounts (up to 10%) of silicon in their composition.
Significant wear can be expected on the piston skirts and cylinder
liners for this engine.
The engine is liquid-cooled; therefore, ethylene glycol present in
the engine oil would indicate a leak in the coolant system.
