oil leak ,doing timming belt

[donsz34]

im doing my timing belt and im trying to fix all the oil leaks. i have a little oil on the timing belt . and when i pulled the intake off there was oil under there. I think it is coming out of the balincer shaft cover .there is a puddle of oil on one side ,top of the block in that little vally next to the head. the o-ring is leaking i no that . Any help would be great. If there is any othere places oil leaks on these motors let me no .

Thanks, Don
