Welcome Mike!


Most likely the gasket between the head and head cover is leaking. No big deal. Just take the head cover off and clean both surfaces and replace the head cover gasket..use a little gasket sealing compound on the gasket when you do. Don't over torque the bolts. Only need 7 > 8 ft lb on the bolts.
