Leak at cam chain tunnel

[Toddk]

I just did some changes to my motor and it leaks at the front of the cam chain tunnel. The cylinders have a lug for a bolt, the head does not. It leaks right there. Do I have different year parts together. I did not put sealant on the square o-ring for the tunnel, was that a mistake?

The early year parts don't have the extra bolt, but mixing and matching shouldn't cause a leak of itself. As far as sealant goes, I don't think there is a requirement to seal the square O-ring. What kind of gaskets did you use? I believe Suzuki changed to a MLS gasket which does away with that O-ring entirely.

I think it's a cometic, it came with a wiseco 1085 kit, I also bought a new cometic CFM20, for when I take a look at it.
