Hi Im David, thanks for visiting the site. can you raise the hood with the engine running and possibly see where its coming from? or get underneath the vehicle ans see if its coming from the oil pan area?
where is the oil filter on that vehicle, left or right side?
what about the filter housing? it leaks from the gasket a lot
ok, look at the valve cover on that side.
