What are some common oil leaks on these engines? I have been looking around on mine and it is coming from the driver side. It is so hard to see anything from below or above on the car when it’s assembled, but if I reach deep down to the rear driver side corner of the rear valve cover I can get some oil on my fingers, it appears to run down the head and block and there is oil on the driver side control arm and then drops down the pan. I think the valve cover is the majority of the leak. Is this a common place? Thanks.
