this is a pretty vast question as its hard to pin point with out actually looking at it but recentlyas in lst 2 days I have 93000 KLMS (Australia) I have a 08 jku never had a oil leak or anything. I have noticed a lot of oil on the front wall and underneath of my oil pan and also all over my oil filter even some slightly behind the lower fan belt pulley? I have inspected as much as I can but I cant seem to tell if its coming from my sump gasket or bolts or something worse I have read somewhere that the timing cover is pretty shity and oil can seep throw. so my question is. is there anything it could be or I should be looking at I don't want to take to dealer at this point becasuse they will take me for a ride and not being in warranty im afraid its going to be a costly fix??
