Front camshaft seal leaking

I've got a b2000 motor in my b2200 and have a leak coming from the front camshaft seal I think.
I took it to a self use steam cleaning place yesterday and gave it the big total engine clean, using spray on degreasers and noticed when I got home that there is a little leak coming from the bit that holds the camshaft down, it has 2x 14mm bolts so I assume that I can just undo them and lift the part off, but can I replace the seal without taking the camshaft out?
I'm pretty lazy so I'm hoping that if it's 2x half moons that I can just do one of them and this will fix my leak.
Has anyone else done this or know if it's in 2 pieces or is it a total removal of the camshaft to fix this leak?

Don't loosen those 14 mm bolts . . .they are head bolts. . .

The black timing cover has to be removed, then the timing belt has to be slacked and front sprocket removed.

That allows the cam seal to be peeled out and a new one installed.

Hmm that was lucky, sure glad I asked first, thanks man
