I have an oil leak that we can't seem to find. It is leaking from the back of the engine on the drivers side, valve covers are dry, intake is dry. I'm thinking that it might be the drivers side head, is that a very common thing?
Thanks

 

May be the oil pressure sending unit.....its at the top of the block on that side.

 

I forgot and left that out, its dry too.

 

I heard guys say that its dry behind the intake but later find out that it is the infamous intake leak. Several people actually.
