Hi Mike,
I didn't see a reply to your post about the disintegrating K&N crankcase filter, so thought I'd share my 2-cents.
I wouldn't worry about it. Replace the rubber grommet/insert and forget about it. If you're really concerned, you can remove the valve cover and make sure there are no bits floating around in the top of the head. Other than that, if the bits have already been washed down to the pan through the oil return passages, then the screen on the oil pump pickup with stop the bigger bits, and the oil filter will catch anything small enough to go through the gear rotor pump. If you have a removable rear cross-member, then you could drop the oil pan and clean it out for added peace of mind. But if you don't have a removable rear cross-member, then cleaning out the pan will require removing the engine.
Basically, I wouldn't worry about it.
Cheers!
Garth

I've had a K&N crankcase filter on the engine in 6328 since is it was
rebuilt in '07. Have realized over the years that the rubber at the
base where it mounts to the valve cover has become heat-hardened and
the retaining lip has begun to disintegrate, obviously dropping little
bits of hard rubber underneath the v-cover and likely into the oil
stream. Not sure how much hazard this is, and the engine has been
running with no issues. Hoping that it's either collected at the
bottom of the pan or has been caught in the oil filter.
First lesson was obviously that I need to change this one out more
often if I'm going to use this type. Any thoughts/comments on any
risks I may now have before me?
Thanks
