i have an 04 KFX400 that recently started blowing a light mist of oil and air out of the hole on the left side of the head. does anyone know what the problem is and what the cause was? can it be fixed or does the head have to be replaced? my spark plug also comes out oily after it runs for a few minutes. any help is appreciated.

im going to tear it down first. im hoping for a blown head gasket. how much for the head just in case?

That weep hole is for water run-off from around the spark plug. The plug sits down in the head so low that there is no where to drain except this port. Was the plug in loose? Was the the rubber spark plug wire grommet seated all the way?

I appreciate your imput. The problem was the grommet wasnt seated.
