I was wondering if the vvti gear(cam gear) has any seals or bearings in it? Or if it possible for it to leak oil through it? Because I feel that it is leaking oil but, if you know of a seal in it or anything else in it that may leak please let me know.

 

there is a seal in there and yes it could leak oil through there.mine is still leaking, just waitting for extended warranty approval.if you do a search there is an article on this.
