Title: Mysterious black thing under oil filter - what is it?
Post by: snailster on November 13, 2012, 01:07:24 PM
When changing oil I've noticed the black blob at the bottom of the oil filter area.
It feels like hard rubber, has irregular margins and cracks, and looks like it may eventually
start breaking off. I was not able to peel it off with my finger nail but pretty
sure some of it would come off if I tired with a screwdriver or so.

What is it? Is it some sort of a deformed rubber plug?
My consolation is that in case it comes loose, the oil filter will capture it.

That's the oil bypass valve.

Stop molesting it, it's fine.  ;)

Thanks, for the ideas!
Sounds like a rubberized end of the valve?
Not sure why it looks like it's coming apart. Will replace it next oil change.

they all look like that. do not replace it. unless you think you damaged it by messing with it so much, but I doubt you did
