When I took my purge valve off today I noticed a bit of oil came out of it. So, I took the two halves apart and noticed that the whole inside of the valve is covered in oil. There was enough oil inside that when I separated the two halves it came dumping out. Has anyone had a similar situation? What would cause this to happen? I searched but only found threads answering questions about the purpose of the valve itself. Thanks.

 

Normal.
