Fuel traces in EGR Valve.

[Amf3ar]

Hi all
I'm from Italy so I'm sorry if my english isnt perfect
I own a 8v '93 sidekick that needs some repairs.
My EGR valve was clogged on "close" so I decided to replace it with a working one.
The problem is after I pulled off the old valve, I noticed traces of fuel in the lower hole.
It is normal?
Another thing...the car makes lots of smoke from the exhaust even if the car is at idle temp...
Here is the photo of the EGR valve.
Thanks for all your great guides!
