ABSTRACT:
An oil level indicating system for an internal combustion engine includes an indicator passageway extending through a cylinder block, cylinder head and up through a ported boss extending through an upper engine cover. The ported boss is sealingly engaged with the cylinder head of the engine so as to prevent fugitive oil from entering indicator passageway, thereby preventing erroneous oil level readings.
