HELP!!! Smoke from cylinder/head !!!

Someone please help me!! I have smoke coming from my cylinder/ head once the quad is warmed up. It smells like oil and I can't tell exactly where it's coming from, but I am getting absolutely no smoke out of the pipe, just from around the cylinder/head area. What could this be?? It looks like it might be coming from all the places with gaskets on the cylinder head even where the carb boot connects but definitely not coming from where the head pipe comes out. Not sure if this has anything to do with it but also have a tapping going on (possibly valve adjustment)

sounds like a loose valve. is it hard to start? have you checked the compression. could be a head gasket as well
