my pred has a place on theeright side of the bike, its splashing oil on the bike around 3-4inches aound it, its made for an allen wrench so i tightened it, i went riding today and it did it again, wth? im getting sick of scrubbing oil off my engine

 

mine's damp around it. probably needs to be removed and pipe sealant put on it.

 

Try taking it out and but some tread tape on it, then put it back in. This might work.

 

I assume you are talking about the little alan plug on the left hand side of the pred(when sitting on it)..........if so, it has a little rubber gasket on the "bolt", might be bad.........
