Be sure to post up pictures! And.. sorry we couldn't point to a more specific location.
If it's not the valve cover, I would consider hoses connected to the intake plenum as strong possibilities. Oh. you could do the PCV hose pinch test. I'll try to find the thread about it.. it's not likely your leak (still possible) but it may tell you the cause of your leak!


Edit: Here's the thread link for pcv location

 

Or clean it up good and see if and how fast it comes back. Could save you a lot of work!

 

^^^ this. First clean it and just watch for a while.

 

Absolutely. I'll have to take some stuff off just to do the clean up, but that's obviously the way to go.

 

Thanks, Pyts. I remember that thread and those pictures. But the PVC valve is just not near where this leak is.

 

I don't think anyone has mentioned the dipstick tube. It's right above the oil filter where some oil is apparent. A possible reason it looks cleaner than the grime on the bottom of the engine is that the oil is transporting grime down to low points where it collects and dries. If you see evidence of oil pushing around the dipstick tube, the o-ring may be leaking, or your PCV system may be unhappy and raising crankcase pressure.

Can I have another guess? I'm on a roll today

It is possible during the prior oil change the oil filter gasket may not have seated completely to the crankcase and allowed oil to weep. Maybe all you need is to clean the old mess, and install/tighten a new name brand oil filter, fill 'er with oil and maybe life will be Fit goodness again.

@Outfit Thanks, Don. I haven't noticed problems with the oil filter or the dipstick, but I will keep those in mind as possible sources of the leak.
