Had to replace the VC gasket along with this OCI on my Focus.
Found that someone had used some sealant in addition to the gasket on the last installation:
I used some brake cleaner on a blue shop towel. Any time the towel got near cam lobes the sharp edges pulled lint off. I noticed this only after cleaning most of the mating surface... that was fun to clean off.
And a close-up of a cam lobe; before I cleaned all the lint off and flushed clean oil down over them.
I think the cams and head look pretty good for 15 years of 5w-20 synthetic blend.
