Been reading great post here for a while. This is my first post.

Ive had a few recent low oil pressure warnings and was preparing to drop my pan today to cleanup the pickup tube.

I added a magnetic plug at the last OC and today when I was draining the oil I Found this.




Any ideas?

The ring looks to be about .3mm thick with a grove on one side and flat on the other. Its about 12mm ID and 14mm OD.

Looks like a small washer or spacer.

Any help or insight you can give may help me save this great car.

Thanks in advance for any help or advice.
