Hi Folks I was just putting in my injectors that were cleaned by witchhunters, and noticed one of the exposed cylinder holes was coated with oil on the inside whilst the otheres were clean, any ideas on what I am working with here

97 4runner 3.4 liter motor thanks for any help.

It will blow out when you fire it up. Witch hunter has a terrific rep and never heard of any issues. Im sure you are good!

oil in the cylinder is more than likely from bad piston rings, or valve seats.
