STR has 2 o-rings & Golden eagle has 3.

With the stock cam seals, I used rtv sealant & torqued the bolts that hold down the cover over the cam seals to spec. I did this on 2 tegs with the cam seal leak problem. Both tegs now leak again. Honda cam seals will not leak in the 1st or 2nd year but they eventally leak. Honda redesigned the cam seals for the 96 tegs; they are better but still leak. Early versions were rubber, then they switched to a hard plastic.
