I'm trying to understanding the construction of the cam shaft rear oil seal.
This started with oil spraying the rear firewall and my trying to figure out why.
There is a rear part alternately referred to as the cam "plug", "cap", "seal".
I can see a dark ring around a round metal, that I assume to be the, rear end of the cam shaft.
Is this dark ring "the" seal or the bearings or something else?
Is the rear cap just a protective cover or "the" seal?
Are there two oil seals?
Will the cam shaft rear "plug", "cap", "seal" shrink or deteriorate over time causing it to fall out?
What is what at the rear of the cam shaft?
I can not find a comprehensive exploded view.
Thank you
