Lower rocker box gasket.

 

Duh-yup!

 

Have you had the rockers off? Like to install Rocker Lockers or for any other reason? Could be that the bottom of one of the blind holes that the rocker lever bolts go into broke off. This can happen if the oil is not removed from these holes before you install and torque the rocker bolts. The material is not very thick right there. They will hydraulically pop off the bottom of the hole. Then you will have a slow but steady oil leak from the bottom of that bolt hole.

 

So have you found the source of the leak yet?
