i would guess inferior alloy quality when they cast the part.

what year machine?  if one is bad, so are others.

got to have a picture of that !

not me you are the 1st to blow the cover off

ok so i read what susan wrote like 3 friggin times, and i still dont understand, but i have been up all night with a newborn and then worked all day so you're all lucky i can still type.  anyways, go there and you will see the end result.





Edited to display images in the post and also allow clicking on them to reach the host site.  The images are the same but use two different pathnames.

Could you have maybe unknowingly banged the cover on something and put a crack in it on one of your rides?

Hmm, Just finding this again as it has fallen back to page 2 behind a pile of other topics.

Are we still saying the oil pressure did this?
The fracture looks like it matched the O.D. of the filter.
Could have a previous owner attempted to install a wrong/too tall filter and attempted to squash the cover on?  It looks like a cookie cutter punched it out.
Find it hard to believe that the filter media didn't puncture. Damifino.
I guess replace the filter, spring, o-ring and cover. Then  see if it repeats. ??? I hate to say that when the cause is still unknown, but at least there would be confirmation of a real prob.
Most oiling systems have a bypass of some kind, perhaps somethings is stuck?

Did the mechanic ever say what he found/thought?
