true, if its not dripping its "normal seepage" as some would say:thumb: . some engine degreaser and a run to the car wash would do it okay,then drive it for a little while and if its really got a leak it will show up again soon. just dont directly spray any connectors or anything.Ok first, the black rubber cover is to access the torque converter bolts. (ok now the tech crap) according to Ford there is a difference between a leak and just being wet with oil. if it is not dripping it is not considered a "leak". Now the real truth, it is really hard to say, however if it just "wet" and not dripping then most likely it is no big issue. I personally have not really seen very many rear main seals leaking on a 6.0L. Could be oil soaked CAC tube grommets (the blue flexable sections at the ends of the tubes going to intercooler) it could be a leak at the turbo itself, either the drain back tube or from the oil inlet. IT is really hard to say, but it is a diesel, they do tend to leak a bit of oil. If you are really concerned about it, and it is leaving puddles in your driveway you can clean the top of the engine with some brake clean and hose it down then drive it, when you return from your drive open the hood and see what is wet.:icon_ford:
You can get it from ford if you want. Probably better that you do, just incase they have to look at it with their lights. Its only like 4 bucks. Dump it in and run it around for a while and at night take a black light under the hood and back by the bell housing and see if you can trace the leak. You might be suprised:thumb:dye from the dealer?
