Embodiment Construction

[0015] Such as figure 1 As shown, the oil level indicator 10 is mounted within a hub 30 integral with the camshaft cover 26 . The hub 30 has a bore 34 through which the indicator vane 12 extends. Hub 30 is in sealing engagement with cylinder head 14 . The sealing engagement extends around the periphery of the uppermost portion of the cylinder head passage 36 through which the vane 12 passes. The cover 26 encloses the camshaft space 64 . this is in figure 1 and Figure 4 shown in . Because the camshaft 18 with the number of cam lobes 22 rotates at half the crankshaft speed, a large amount of oil is thrown around the camshaft space 64 . However, because the camshaft guard hub 30 seals against the cylinder head 14 around the cylinder head passage 36 , escaped oil is prevented from entering the indicator passage from the camshaft space 64 .

[0016] Such as Figure 4 As shown, a portion 46 of the indicator passageway extends upwardly from an oil sump conduit 52 of the cyli...

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.

Description

technical field [0001] The present invention relates to an internal combustion engine oil level indicating system wherein a linear indicator extends through a passage leading from the top of the engine and into the engine oil sump without any external additional piping. Background technique [0002] In its simplest form, an internal combustion engine oil level indicating system typically consists of a linear indicator implemented as a wire or a thin flexible vane that allows the linear indicator to enter lubricating oil stored in the engine crankcase sump for Provides a direct indication of the oil level. Such indicators often use externally mounted pipes, which sometimes extend through the sidewall of the cylinder block. Unfortunately, such ducts can be damaged during operation of the car, or during storage and installation of the engine. Furthermore, such ducts take up space, which is almost always lacking in the engine bay of a modern car. While some engines have indic...
