you most definitely have a leaking front cam seal. this is exactly where the leak shows up.

when you change it i suggest you buy a very small length of 1 7/8" OD diameter white pvc plumbing pipe. cut a piece 3 or so inches long and after hand setting the seal use this pipe to set the seal the rest of the way in.

if you set the seal all the way in until it rests against the inner stop of the head your leak will be gone.

when you pull out the old seal you can see how far in you need to go.

you need NOT remove the entire t belt to do this job.
