The only things behind that big heavy A/C bracket that can leak are the lower and upper oil pans and the dipstick tube, right?

I just took that bracket off last night - a little bit of oil on the backside. It came from the timing chain cover - it was all grimy there, nothing near the pans or dipstick. Haven't had to add any oil, so it's a non-issue to me

What about the front crank seal? A lot of times if it's leaking, it will throw oil all around the area.
