It's not leaking out of the cover where the pump goes in is it?

It gets too hard to see all of that, I have to tear apart the front end just to see ( take out radiator,intercooler, and fan shroud)

Default leak behind pump

Don't overlook the timing pin. Just lost mine last week. The thin, press-fit retaining washer sometimes dislodges and leaves the timing pin ten miles back in the "Deliverance" neighborhood you just passed through. Or the oil ring on the pin allows oil to wick. I fortunately have a backup engine with an extra pin and washer. A dry 3/4" expansion plug from the hardware store may stay in place until a replacement shows up in the mail......

Took a closer look and it seems as the cover has a Crack in it, possibly from when the motor was put in.
