Oil Leak

[WhipE350]

I would eliminate the obvious easy to identify things first. Take both wheels off and clean around and under the the coils as best you can, you should find you can get it nice and clean/shiny. I recently change my plugs and did this. I've since noticed a little seeping of oil on a couple of the tubes so I'll likely go back in an put new o-rings in. No drips though. Check it again after running a few trips.

I would also check the oil fill tube that crosses the engine from the filler, you cant' miss it if you take the engine cover off. When I got my car in Nov it was clear it had leaked at some point, I cleaned it up and check it occasionally.

I'm having trouble telling what those photos are of exactly. I'm sure there a more experienced folks on here that can give you an idea. Are you sure it is engine oil.
