Hi I have a 2001 Quad Master LTA 500 with an oil leak from the valve cover . From what I can see it looks like it is coming from the silicone gasket . Now is it a big job ? Do I have to send it to a dealer or its something I can do ? I am somewhat mechanically inclined but I am looking for some tips . From some research I did looks like no paper gasket exist for it . Help and Thank you Gabriel .
