I would use some brake cleaner to try and wash that gunk out.

When I did my ccv It seened like the o ring needs to sit inside the hole fro the dipstick tube. I had a hard time getting the new one in so i lubed it up with some oil gave it a tap with the hammer and it sliped in. I guess what im getting at is if it fits and doesnt leek It should be fine.
