oil leak drivers side rear
I have an oil leak that has me lately baffled it's not everyday it's only in the morning so it's as if after it sits for a while it drips I looked at the oil pan and its not near it does an exhaust pipe or the engine pipe that is stained with oil burn marks so whatever it is it's dripping from the engine on to this exhaust part that's barely bigger than the rest of the exhaust I guess like a resonator what area could be dripping I didn't see an oil pressure it doesn't seem like it's the valve cover or whatever cover you want to call it any ideas but again it's not every morning this happens and believe it or not in the summer never happens but in the winter it does

This is most likely the cam plugs. There are two plastic caps that snap into the back of the head on the left (USA driver's) side. They are known to leak. Both are less than $20 at the dealer and fairly easy to replace. They are hard to see, but you can do it by feel. Pry them off with a screwdriver, then snap the new ones in place.

So it turns out that one of the guys that replied to my post was right there are these two plastic plugs what is 35 millimeter 1 inch 65 millimeter the 65 millimeter was the one that was leaking believe it or not it's cheaper to buy this at the dealer than online $12 for the larger one $7 for the smaller one replace them both there are videos on this it is so easy to replace all you need is a small flat head screwdriver to slowly try it away and just literally pop it off with your hand when you replace to 65 millimeter 1 make sure you're quick because oil will leak out

If the same cam plug is starting to leak again, you should make sure that the plug is inserted all the way into the access hole. If it is firmly seated and you can't definitely see the leak from the plug (oil at the bottom of plug and none on the engine above the plug), it could be coming from somewhere above.
IMO you shouldn't use a glue......
