head cover leaking oil

[03trx400]

just noticed some oil leaking from the two allen head bolts on the left side of the engine..rocker arm bolts i think? anyone got any idea what could cause this?

yeah i had same prob. copper washers on the inside there. probably got wore out. don't forget to purchase your rocker top gasket before hand so you don't open it up and then realize you can't put it back together. this is a fairly simple fix. email me if you got other Q&A. not sure the next time i will be on here.
